Wow. You are my new go-to source for my RC heli hobby. I consider myself an intermediate pilot but your content is absolutely invaluable for everyone and I’ve already learned key info. I own a few of the helis you’ve covered and I’m very excited to raise my game thanks to you. Ive followed several online / TH-cam sources with only a very select few actually useful & easy to follow. I’ll be purchasing your ebook without second thoughts. You have raised the bar big time. Good work!!
Even though I have yet to move to Open TX, I now understand basic setup for micro helicopters. ALL your videos have taught me something of value. I can set up all my XK, Eachine and Yu Xiang helicopters in the Xk X6 controller perfectly. Even the Spektrum DX6E benefits from your teachings. Thanks again. PS: I can hover and move around a lil better in agility mode now. And I am breaking less parts, 😂.
I really enjoy watching your videos over and over. Your explanations are clear, precise, and thorough. I especially like the way you explain the basics of RC helicopter transmitter setup. john if I said this once I'll say it again. I really enjoy watching your vids over and over, I also like the fact that you also go back over the steps to recap.. recently got the radiomaster tx16s, watching your video on the goosky and omp, made a tough decision, Got the goosky s2 cause I really liked the ease of battery replacement..
ALWAYS know I’m getting the definitive word when I read your e-books or follow your videos. Special thanks for staying out of FULL GEEK MODE when describing OpenTX setup. I’m gonna HOLD my breath till you make “the next video” on setting up an eCCPM flybar Heli in OpenTX ;-) Thanks again for these tremendously helpful videos.
Thanks John, just what I needed , brilliant explanation of setup, worked first time, great job and top knowledge, I've just gone from dsm to opentx due to flying drones and then realised I need to setup my heli, I'm a happy man :)
I wish I'd seen this video or one like it before I first-flight-crashed my Eachine E160. With the default setup on the E6 radio, when I brought the throttle/collective down quickly, the resulting negative collective slammed it into the ground, breaking the landing gear and swash-plate links. While waiting for the replacement parts, I edited the collective points upward at the low end (after writing down the original).
Hi Thanks for the very informative video. I am new to opentx and having difficulty in binding nano CPX and Nano CPS on my Radio Maser TX16s. I've had no problems with WL toys programing and binding. Any help would be greatly appreciated . Thanks
I just programmed my first flybarless. Model using companion wizard and choosing airplane which gives the first 4 channels. Added channel 5 and 6 for gyro and collective. Love the flexibility of open tx. Flying the model on accurc sim on x9 lite. Waiting for delivery multi. Module for spektrum and futaba . My flight modes only change the throttle percentage. Use the same linear curve for pitch . Added a mix for gyro by assigning pot switch to add or subtract the gyro value to fine tune tail gyro on newly built model.
Hi John, thanks for the Video, I followed these instructions on an XK K110 today it found it really nice to fly. I also tried it on an E160 and I’ll give that a try tomorrow.
It took me awhile until I found your videos. Great each one of then. Do you have any video or references on how to setup K123 on OpenTX and how to adjust the pitch like you did on this K110 video? Thank you and congratulations on your excellent videos.
As always, thanks for a great video! Noob alert questions: 1) In normal mode 0 to +8 collective; how do you land the helicopter if it doesn’t have negative collective? 2) Why is it called dual rates when there are more than two rates?
1. Why and physics are covered in detail in my setup and tips eBook: www.rchelicopterfun.com/rc-helicopter-tips.html But the primary reason is gravity. 2. Because all radios used to only have 2 position toggles for that function (thus dual) and the traditional name has stuck even with tri position toggles.
I have a question on omp m1, the wires came out of the plug for the tail motor, the black wire still connected to the end socket, I need to know where the blue and red go, if I know the middle wire that would be enough. How can I wire to a new connector, what do I need, ythank you, your help will be much appreciated
I'm not a Rotor Flight user. I fly Bavarian Demon and Ikon mostly plus it's a big time investment in learning, getting used to and fully trusting a new system. With that said, I'm interested in trying the new RadioMaster Nexus which as you likely know runs on RotorFlight, but it at least has been properly tested and tuned by others as I have no time nor desire to beta-test open-source unknowns, so we will see what the future holds. Jonas of course has already done a full Nexus configuration video which I can't hold a candle to.
Great video very informative, my xk k110 drifts to the left pretty aggressively right out of the box. seems like 50% trim to the right helped but it still wants to pull to the left, I have to stay on the stick and give it constant input to the right even after I calibrated it in 6g mode several times because I don’t know how to fly 3d just yet, does it sound like I may have a defective helicopter?
Check and level the swashplate to see if that helps (a little right tilt to the swash is okay to counter the left tail rotor translating tendency - just a smidge. Have you even tried it without the artificial self-level help turn on (ie normal 3 gyro mode)? If it is fine in normal 3 gyro mode, but drifts with the accelerometers turned on, and if you can't successfully calibrate them, then yes, that sounds like a defect issue (if you have confirmed the swashplate is level). With all that said, a nice tame learning to hover/fly setup in normal 3 gyro mode will be almost as easy to fly as if the 6G (self level help) is turned on, and you'll be learning the real feel right off the bat so you won't have to relearn it all over again when you turn self level help off. But do check the swash level since that is key to having a well trimmed bird off the bench.
John Salt thank you so much for your reply I really appreciate it, I’ll give 3D a go next flight and hopefully it doesn’t pull to the left in that mode.
Thanks so much for this video. I just bought this heli and using your setups make it fly very stable. My only issue is I require a lot of right trim to get the heli to stop drifting. So in my case the swashplate is tilted right. I’m new to this so pardon my ignorance. Is it ok to use digital trims on a flybarless heli? If not, how can I get swashplate back to level and not have drift? Thanks
@Mark Linder - you have to mechanically level the swash by pushrod adjustment. Radio trim on FBL should never be used. Some FBL systems without mechanical servo to swash pushrod adjustment (ie. fixed length servo to swash pushrods) will generally have FBL internal servo trim programming to individually adjust each of the 3 eCCPM swash servos to level the arms and get a level swash, but the K110 requires mechanical leveling.
And now I am mounting a TREX 470LP. I am new in helicopters.... is there any placer where I could take an OpenTX configuration for such model? My radio is a Jumper T16 with OpenTX. Thanks!!
Very interesting and useful. I have already bind a E119 in a Radiomaster TX16S using the layout for heli that is already in the radio, but it is for a CP model. The question is, how do you adjust this profile for a FP heli? Best regards
@@Rchelicopterfun Thks John, it worked flawlessly. Now, how do you untame this heli. In the original transmitter there is a button to make it fly more agile. Regards
I have an e160 that I’ve been really struggling with and used these same settings (instead of the 3D ones all over you tube) and now am able to actually fly it a bit. I’m still a complete learner but couldn’t even hover it with the other settings.
Set my Fusion 270 up with OTU. Everything work except the motor won't come on. It did with another Tx, but not with my QX7S. It's something in TX setup, but I can't figure it out. Any suggestions?
Look at your channel output monitor and see if you have throttle output on your assigned throttle channel. If not, then you have to start digging through your OpenTx configuration. There are so many ways to alter the outputs on OpenTX after all. Might be something as simple as not low enough throttle signal to arm the esc or throttle signal is backwards. Lots of other possibilities of course.
John, great video, very illustrative. I just set an XK K110 micro heli, following your video. It is already flying, but I have a concern regarding the throtlle. In normal mode, the heli starts spinning at around 40% travel of the stick. How do I fix it? Regards
Hey John, finally received not one, but two TX16S transmitters (I thought I had damaged the first one accidentally but I had bad batteries). Now I need to figure out what receivers. Have you got any guidance on selecting one? I’ve got 4 helis waiting to fly including esky f150, eachine E160, Fireball Havok, and OMP M2V2. I also want to get a 700-800 size once I master these too. Every rx I find seems to be geared towards FPV/multirotor. Thanks again for the great videos!
I would first determine which flybarless system you are getting for a larger heli and then you will narrow the list knowing which RX compatibility the FBL system requires.
Hi John, love the series with your concise logic, and I'm using this to set up my K110 on my Tango2. Struggling to find enough switches though? Should I add the separate rudder settings into low-high rate switch and use the now free switch for the throttle curves? OH, and another question (sorry). From size and gimbal travel, would you say the x6 & RM tx16s are similar? I wasn't blessed with big hands so wondering whether the TX12 would be better for me? Any input would be great - keep flying :)
If you have limited toggle switches then combining all DR functions on a single toggle makes perfect sense. X6 is smaller than the TX16s and very different. No idea how much smaller the T12 is than the TX16s.
Hey John, how are you doing? I cant't find your video where you set up the throtlle cut. I have a question regarding nitro helis, what switches you use for throtlle hold and throtlle cut? Regards
Thanks. However when and how did you set up the collective pitch? Do you not need to program the cyclic and pitch in the input screen to enable the collective pitch to work? Or did the automatically set up because you selected the heli mode?
Not sure I understand your question "setup the collective pitch." Collective pitch setup starts at 17:06. If you are asking about an eCCPM (electronic-cyclic-collective-pitch-mixing) setup, like almost all flybarless RC helicopters, the K110's flybarless system (flight controller if you prefer) does the 120 degree 3 servo eCCPM mixing internally. There is no radio eCCPM mixing required. Just that you setup your collective channel output (ch 6 in this case) with your various pitch curves. Only if had a heli that didn't do the swash mixing via the flybarless system (Align 3G or 3GX for example) or any flybared 120 degree eCCPM heli, would you have to enable internal radio eCCPM mixing, and that would be done in the heli setup menu on the radio to select an internal radio eCCPM swash mix program.
Question, how do you know which channel is the throttle channel? Or does it not matter? I think it would. I'm trying to setup an eachine e150 on the radiomaster tx16s. I want to do it properly. Thanks, Dennis
Thanks for the very informative reviews I have just received k124 which bound to x6 ok. A couple of minor bumps and now it's unresponsive. No bind lights just slow beeps. Does anyone know what?
I regognized "white" version of K110 (not K110S) has also 2 versions in the controller setup! Old version throttle can be regulated from -100 to +100. (0 to 100) Newer version have only from -100 to +40 (0 to 70). From +40 to +100 no increase of throttle. That is crazy. Improvements on this heli: a) GNB 520mah HV LIPO, +0,15 Volt increase the RPM, Lipo fits without issues b) Change plug to GNB27, 0,05 to 0,1 Volt more efficency c) Change tail blade to Blade mCPX/2 (need small driller, drilling by hand to open hole 0,1mm) 4 years of K110 experience: - Number 1 end of lifetime. - Number 2 not found in deep gras - Number 3 left in a tree - Number 4 with black motor - Number 5 and 6 with purple head on the motor. (since 1 to 1,5 years available) - Number 4 and the 5/6 fly different. Now I understand why :) kind regards Timo
John. What with your experience, passion, ebooks ( i have three) and you tube coverage, we learn all we need to know re Helis. I just love that Radio!!!. I have the T16s. I notice you did not use the HELI icon. Do we not need this then? Somebody told me the Heli symbol is only for flybar types but that doesnt sound right. What about swash plate set up? Do we need HELI for that please? Peter
@Peter Cane - I'm not sure what "heli icon" you are referencing? If it's the little red circle shown in the model setup screen (a little airplane shown in this video), it really has nothing to do with radio outputs since we are programming those anyway. You do have to have the "no heli" box unchecked however in the build options so you can activate CCPM swash mixing type for helicopters that require internal radio CCPM mixing. By the way, flybar or flybarless has no impact on type of CCPM selection, it has to do with where the swash mixing occurs (externally in the helicopter or internally in the radio system). You can have external swashplate mixing on both flybarless (most of todays FBL systems do the CCMP mixing) or old mechanically mixed flybared helicopters (swash mixing is done on the heli mechanically). Likewise, you can have internal radio swash mixing with flybared helis that don't use mechanical mixing or some FBL systems like the Align 3G & 3GX that don't do any swash mixing within the units. I cover all this in two separate videos I made on OpenTX for helicopters. Part 1 - No radio CCPM mixing (external mix): th-cam.com/video/XdFOndPG7xo/w-d-xo.html Part 2 - Internal radio CCPM mixing: th-cam.com/video/AaNx-83WJeg/w-d-xo.html Hope that helps...
@Peter Cane, the H submenu is used for swash mixing programming. It's only used with internal radio CCPM swash mixing, not external mixing which is why it wasn't used on this K110 heli example since the FBL system in the heli does the CCPM mixing. I cover using that H submenu in that second OpenTX heli video I mentioned above (internal radio CCPM).
@@Rchelicopterfun Okay John bear with me I am an old noob!!! I have to set financial limits to my new obsession so I limit t my helis to very small ones. I have two S3s, an XK K110 in the post and I look forward to getting an OMP Hobby M2 Explore. So these three already have internal mixing and do not require the H icon but Noheli left unchecked yes? On the newest open tx SD card firmware version there is no Heli wizard. Is this right? There are quite a few of us that are experiencing difficulty setting up an S3 with a T16S and most describe it as " Tricky". I went out and bought a DX6E to do it but its niggling me that I cannot do it with a T16S. Would you be kind enough to do a vid on this ? Thanks John for getting back to me. You deffo know what you are doing so I will copy you. Making a training skid but I have to think hard where to get the balls. Thats half the fun. Peter
@Peter Cane - Sorry, I don't know what a heli setup wizard is on OpenTX? There never was one that I know of since using OpenTX from 2017 onwards. I've always used OpenTX University's base template which is what I show in those two videos and I use it on every collective pitch heli I own from little micros up to 820 size turbine. The Nano S3 would be setup identically as well. I don't have an S3 to do a video on one, but again, it would be identical to any other collective pitch helicopter setup. The only difference with it over this K110 example would be it uses Spektrum channel mapping order (TAER) instead of Futaba order (AETR). I even go over that in the second video above where I discuss creating additional OpenTX templates (4 in total) so you are covered for both Spektrum & Futaba channel mapping for both external & internal CCPM. As you'll see in that first OpenTX for helis video (external radio mixing), you don't necessarily have to uncheck no heli in the build options if you are only going to have/setup/fly externally mixed CCPM RC helicopters (such as all the ones you have listed). All the no heli box option does is remove that swash mix sub-menu from the list. However & as I point out in that first video, it's generally in your best interest to have that swashplate mix menu in your base heli template for if/when you may get a heli/s that require internal radio swash mixing. In other words, it somewhat future proofs your base OpenTX heli template.
John, I might be wrong, but it seems to me that at minute 23:46 the curve PtN might have aprox 9 degrees at the upper stick position as you said, but at midstick it is not zero degrees. Zero degrees are attained only at the low stick position and pitch increases to 9 degrees at upper stick position. Regards.
Yep! Anything under a 200 size machine I consider micro. Regardless, CP setup is setup. I setup my 700 & 800 size machines not much differently than my micro sizes for various flying styles.
It depends on the flybarless system. With most higher end FBL systems you set the max cyclic travel in the FBL unit. Other basic FBL units, yes, you can limit the travel outputs in the radio for the cyclic travel on pitch & roll channels (elevator & aileron).
@@Rchelicopterfun thanks John. So this is with the OMP explore. I've had to order the M2V2 as I could not fix the issue with the explores tail not holding and blowing through motors. Disappointing but hoping for better luck with the new one.
When you went to create a new model for this Heli it brought up a menu on the side that said 3D helis along with other ones but on my TX16S transmitter with open TX with the newest firmware downloaded when I go to create a model it only pops up a menu saying glider or airplane as the only options it gives me. Am I missing something? I cannot figure out how to choose helicopter or 3D helis or anything like that.
I simply created those extra categories (same thing as creating extra file folders). In openTX in the select model menu, there are 6 options: Create model, duplicate model, move model, create category, rename category, delete category. It's that simple.
Another question, John. I see you adjust the collective range (24 degrees) in the outputs (ch. 6). But I thought the pitch curves was setting the collective range? Obviously not. Do you have a short answer to my misunderstanding?
Pitch curves set your individual collective ranges for your different flight modes, what I'm doing initially with the +/-12 collective is setting the maximum possible collective range the helicopter can produce.
As I state and demo in the video, I first created two generic heli models (3 if you included the generic Futaba model with ch3 throttle). These 3 generic models are the base foundation for my inputs, mixes, outputs & curves. After that, every new heli model I enter, I will use one of those three models by duplicating it. I then select the model, name it, attach an image file, and go through all the setup steps along with creating logical functions and telemetry setup for the larger birds. In short, every model I have listed in the radio, I created & customized myself, but every one of them is based on one of the 2 generic collective pitch model foundations I first created. It took me over 6 months to slowly switch all my helicopters over to OpenTX & FrSky when I made the switch from JR/Spektrum. Yes, it's a massive undertaking switching systems. I hope I never have to do it again, but in this hobby, that would be unheard of.
Dear john, maybe you can help me.... I also have xk130 that i bought year ago and just sitting in my garage cause it doesn't fly good.... The problem is that when ever arm it, the swash plate on the right side tilts up.... I have setup all flat and nice but everytime arm to fly it tilts so on hover blades are tilt in steady hover... I have replaced theain board and still same..... Help me please...
I would really have to see it first hand to correctly diagnose; but it sounds like the servo arm on the servo in question has likely cammed out one or perhaps more spline places on the servo output shaft. A servo gear could also be stripped in that servo causing it to jump out of position. Just guess of course without seeing it first hand.
Hi John, Correct me if I'm wrong. Setting up my XK-110 with my Jumper T16, I found the Throttle and Pitch hold switch (SH) would not work since it is a toggle switch. I choose (SF) switch, a two position switch and the heli will not spool up in hold mode now. Everything else worked as you explained. Respectfully, Barrett
Howdy Barrett. Yes, I physically swapped my rear toggle switches around so the sprung momentary is on the left and the normal two position on the right (like I'm used to all on my previous radios over the past 30 years). So what you did there by using the SF toggle on the left for your throttle hold activation is spot on correct. The next statement however "the heli will not spool up in hold mode now"... I don't see any problem with since that is the whole idea of having throttle hold turned on - the heli won't power up when hold is engaged. So I need clarification on that because it's working exactly the way it should. If something isn't working correctly however, use your channel monitor screen to help fault trace. As I so often say, it's one of the most important tools that computerized radios give us to help figure programming issues out.
@@Rchelicopterfun Thanks for the quick response John. No issues with function of hold mode. I could have stated that better about the spooling. Thanks for clarification. Respectfully, Barrett

Awesome video, John ... as always! Thank you! I set up my K110 with all your settings, but you don't explain HOW to setup the gyro gain/values. I tried to copy your setup but I don't think it's working. The switch indicates it's going from -100 to 0 to 100, but I can't confirm the model is switching/entering the two modes properly (don't want to do a test flight until I KNOW it's working PROPERLY). The method you showed in the video doesn't seem to work on my model. Shouldn't a LIGHT on the board CHANGE when you're in 3D vs. 6G??? My lights stay the same (red and blue both on solid). Also, my two aileron servos are not centred/level (no idea WHY). The one is slightly low and the other is slightly high. Sooo, the swash is not level side-to-side. HOW do you level them? I've leveled legacy helis in the past using sub-trims, but I have NO IDEA how to do it on a micro with a flight controller. Do you adjust the aileron mid-point or something???
@TechNoPhobia - There are no remote gain adjustments on the K110. Like most modern day micro size FBL collective pitch RC helicopters, channel 5 only controls the mode of stabilization. Either normal 3 axis gyro mode selected, or self level mode activated. Basically a this or that selection with anything from about 0% to -100% travel output putting it in one mode, 0% to +100% travel output in the other mode. *No gain adjustment at all.* There is no LED color change or flash sequence on any of the XK helicopters to indicate which stabilization mode you have selected. However, like any FBL unit that also has a self level mode, it's pretty easy to visually determine by swashplate tilt behavior what mode is selected. In self level, the swash will generally stay tilted after a cyclic command or heli movement. Whereas in normal gyro mode, the swash will slowly level back out after a cyclic command or heli movement. Or just hover the thing to feel what stabilization mode it's in as it's pretty obvious. 🙂 If you are not getting a mode change by channel 5 activation, you'll have to confirm on your radio (servo/channel output monitor screen) you are getting full channel 5 travel in both directions with whatever toggle/activation method you have selected to control channel 5. If you are not seeing any channel 5 control, you'll have to recheck your channel 5 input/mix/output programming setup. I know of know way to electronically level the servo arms on the XK micro helis. I've always made adjustments mechanically if required to trim them out (in normal gyro mode). Mechanical adjustment procedure is the same as it is on any RC heli... first servo arm spline selection to get the arm as close as possible to a level position, then pushrod ball link threading adjustment to level the swash.
@@Rchelicopterfun Wow! Thx a million for the QUICK, detailed reply! My swash doesn't react like yours in the vid to indicate EITHER gyro mode. When I tilt the heli, the swash stays put (maybe I'm not 'doing it right'???). I'm using the SB switch and, yes, channel 5 is indicating -100, 0, 100 output in the monitor. Dunno what I've done wrong. I don't want to do a test flight because I CAN NOT fly without stabilization. Period! I'm used to fly bar helis that 'self-level' (in normal flight mode, I guess) when the cyclic stick is centred. These FBL helis that stay in one position when the stick is centred are beyond my control! I just crashed my brand new E160 when I switched it into 3D cuz I couldn't friggin' KEEP it level. It was BONKERS! I also had 100% travel and no EXPO tho, which was an oversight in the heat of the moment! If I'd reduced the travel, I MIGHT have regained control. We'll NEVER KNOW!
@@Rchelicopterfun So I flew my K110 last night and everything seemed to be OK ... sort of. Didn't have enough collective range so the bird didn't want to climb, especially in normal mode. Increased that and it was MUCH better. As far as the tail goes: NOT enough gain! There HAS TO BE a way to increase the gain on the gyro using OpenTX! Using the XK X6 radio, the tail is LOCKED IN ... BEAUTIFUL! Using the TX16S, the tail is pretty bad. I noticed it RIGHT AWAY! Even just taking off, the tail was drifting left, which it NEVER did using the X6. The X6 gains are set at 75 and 25 FOR A REASON. They're not set at 0 and 100. Using the TX16S, the gains are set at 0 and 100, effectively. There has to be a way to set them at 25, 75 using OpenTX. I'm REALLY surprised you said in your review that the tail was "locked in" using OpenTX; that certainly wasn't the case in MY experience. In fact, the tail was SO NOT locked in that I immediately considered going back to the X6 radio to fly THAT model. I totally trust and respect your advice/opinions, but my experience was totally different than yours with this model. I'm probably doing something wrong.
I don't understand what you are asking about "setting". What setting? If you are referencing collective pitch RC helicopter setup, size of the helicopter is irrelevant. You setup a collective pitch RC helicopter to produce the amount of performance you want out of it based on how you want it to behave & your flying style/experience level. As I say in the video - that is the fundamental constant for all collective pitch RC helicopters regardless of size, brand, or power type. www.rchelicopterfun.com/rc-helicopter-tips.html
Great video, I don’t know if you can help but is there any way I can turn off the safe mode on my Blade nano CPS. I’m using a dx6i. I can turn it off in idle up with the gyro switch, but I can’t get it to turn off in the first mode. I just want the first mode to be similar to the factory set up but without SAFE. I can’t work it out.
Like most micro helis, the Nano CPS SAFE (auto level stabilization) is activated and deactivated through channel 5 output (just like it is on this little XK K110). I believe in the Nano instruction manual for programming, they suggest mixing the channel 5 output to the flight mode toggle so your flight mode toggle is what turns SAFE mode on. If you don't want that function, then you would have to turn that mix off and have channel 5 control through the gear toggle instead.
John, just to understand the way you fly. Do you use three switches to set the flight conditions: the rate/expo of aileron/elevator (SD), rate/expo of rudder (SG) and flight mode (SE)? Regards
Pretty much. Like most traditional collective pitch RC heli setups, I use a 3 position toggle to set my 3 separate pitch and throttle curves for my 3 flight modes (plus a separate hold throttle & pitch curve) which naturally overrides any of the others when I engage throttle hold. As for dual & expo rates, I personally like having a separate cyclic dual rate toggle and rudder dual rate toggle and use two more toggles for them. With OpenTX (and most other computerized radio OS systems), all the dual rates could of course be coupled to the same toggle as the flight modes so it's all controlled from a single toggle for those that find that easier. I just like having the ability to separate my dual & expo selection from my pitch & throttle curve selection, especially for scale or F3C type flying.
Sorry, I don't share my files. Why? #1 & main reason... It would not be fair to all my customers / students who paid for my collective pitch setup & tips ebook along with my my setup help & instruction over the years. They are the reason this channel even exists. 2. It doesn't teach people a thing about how to properly setup a collective pitch RC helicopter or use OpenTX. 3. It's a huge hassle then trying to explain how my specific settings work and why I configure my radios the way I do. 4. I know exactly what happens because I have tried it for a few people just to see how it would play out. People just used the settings unaltered even though I warned them about that. Not a single one confirmed the mechanical setup of their heli first, and then adjusted the outputs accordingly so the collective range and the symmetry of their collective range would then be correct for proper pitch angle. These are not mechanically simplistic quad copters after all; every single collective pitch RC helicopter has mechanical variation - even the exact same RTF models. The result of all this... A crash on first spool up, and I get blamed for it because they didn't understand the basics of collective pitch setup. Never again.
Good eye! It was my mistake. I must have deleted that specific switch position by accident as it was in there initially. It still works fine of course since there is no other switch option there so in normal mode, it just defaults to the normal throttle curve. But yes, it should have shown the SE toggle with arrow pointed up just as it shows for channel 6 normal pitch curve selection 6 lines below.
hi john so great that you have done this, i also asked you for this on your k110 video as i have a jumper t16 and a k110 so open tx is similar in layout beteen the t16 and the horus. This is very cheeky but could you upload this setup for the k110 for download, i would be very grateful kind regards from the uk Mark

Not a single one confirmed the mechanical setup of their heli and then adjusted the outputs according so the collective range and the symmetry of their collective range would then be correct for proper pitch angle. These are not mechanically simplistic quad copters after all; every single collective pitch RC helicopter has mechanical variation - even the exact same RTF models. The result of all this... A crash on first spool up, and I get blamed for it because they didn't understand the basics of collective pitch setup. Never again.
One question, if you don’t mind On minute 10:05, on the radio screen (first setting) you have as channel 1 thr, is that correct? If so, what settings do you have in that channel?
At that time index (10:05) I'm actually setting the inputs (what stick or switch is assigned to what function). It really makes no difference what order you create your inputs as it has no bearing on channel mapping. I just use the order I'm most familiar with (TAER). Setting your mixing in OpenTX is where you assign your inputs to a specific channel. I go over mixer settings (what channel you map your inputs to starting at time index 14:44. In this particular example as I explain at the beginning due to Futaba's AETR channel mapping (which this specific K110 heli uses), I have throttle assigned to channel 3.
John, you show the values on the Horus, but have you programmed all that on a pc first, then loaded the open tx model to the radio? I assume you don't program on the radio, right? Thx
I perform all radio programming for all my models with the radio alone. That is the benefit after all of a computerized radio - direct programming without the hassle & complexities of external devices. 🙂
@@Rchelicopterfun John, thank you for that, and for the " Salt University" here on You Tube. It's the reason I bought a Horus 12, and numerous other suggestions. Stay Well!
I make mine out of thin cardboard. I outline and show the entire process in my setup & tips ebook in chapter 3 on micro CP heli setup. www.rchelicopterfun.com/rc-helicopter-tips.html
FBL stabilization selection is controlled by channel 5 (on most micro helis), so you would set your channel 5 output however you want to change it from -100% to +100% such as a toggle switch.
The iRangeX IRX4+ : www.banggood.com/custlink/mDGGvFWyft I've done a review on it: th-cam.com/video/-xz7zs6G-j0/w-d-xo.html I run it in serial mode: th-cam.com/video/XmUIdMsBnZI/w-d-xo.html
Nose-in orientation doesn't change a thing on the heli, so no idea there other than normal lean caused by tail rotor translating tendency that perhaps you don't notice as much when it's pointing tail in.
Hallo John, do you know how I can bind a VOL Toys XK450 from WlToys with S-FHSS? I cannot find the Bind Button from that VOL XK450 ? And do you know how many channels I must use and how to do a setup for the channels? That would be an amazing new Video for you to do ;O) Thanks beforehand
Program them yourself to match the mechanical setup of the heli, your skill level & your flying style. That is the only way to have a properly setup collective pitch RC helicopter.
John, at minute 13:55 I notice that your toggle switch SG moves in the opposite direction than switch SD to choose from 100 and 50% dual rate. Is there a reason for that? Regards
It just my preferred method of toggle position when I'm in low or high rates. In low I want my upper toggle (SG) to be in the rearward position and my front toggle (SD) to be in the down position.
@@Rchelicopterfun Ok, thank you again for your patience. You relay very much in your memory to remember that!!! For me, it would be simpler to uniform the action of all switches. Regards
Back in the day before computerized radio', all dual rates selections were default to those positions that I use. That subconscious memory after close to 40 years of RC flying is not easy to change - why it makes sense to me. Of course, that is the beauty & power of computerized radios, we can configure them any way we want.
This video addressed the radio and helicopter setup portion of RC helicopter setup. That is different from the flybarless system configuration & setup. Regardless of what flybarless unit is used or even if it's a mechanically stabilized helicopter (flybar), collective pitch RC helicopter is very much universal and all these same steps I show with this little micro CP heli are done with all sizes. As for flybarless system setup & configuration (RX connectivity type, servo travels, centering, pulse width, gains, travel limits, gyro direction, swash leveling, piro-comp, etc.), that is unique to each flybarless system and the best tool you have for that is the flybarless system's setup wizard.
Hi, John. I am wondering if with the new wave of transmitters in the market someone has set openTX v 2.3.10 for a heli with this features: nitro, CCPM 120 (requires command directly to the servos, not thru gyro), expos and throttle trim on. For now, I was able to adapt CCPM configuration for the Taranis (that is in the OpenTx university) in a MiniTitan, but I think there are still some missing issues to fully exploit the new transmitter, the way a simple Futaba 7C can be configured to fulfill the configuration of a nitro heli as described above.
Yes OpenTX can control a normal eCCPM heli. It will allow 120 degree mixing within the radio for traditional flybared machines or ones using flybarless systems that don't do the 120 mixing internally. Now I'm still running 2.3.9 but there is no reasons things will have changed in 2.3.10. They haven't changed yet in countless updates after all. I won't of course know for 100% sure until I update, and I always wait a good month or two before doing that in the off chance there is a bug in the new release. I have several fly-bared machines with 120 eCCPM and several more that use Align's 3G & 3GX flybarless systems (electric & nitro) - all working fine with OpenTX . You of course have to make sure you have the heli option enabled in the Companion build options for the radio so you can select the different swash mix types in that menu.
@@Rchelicopterfun John, thks for your fast answer. I indeed watched your video regarding throttle trim with much interest. I am not quite satisfied with the way it tries to solve the problem, mostly because it would still affect channel 6 in pitch control. Regards
Not sure what is lacking or how it would effect CH 6's mixing outputs? Everything works perfectly as it should on all my 120 degree eCCPM mixed helis in OpenTX, just as they did when I was flying them with pre-configured computerized radios. One crucial & important item however is to make sure you set your dual & expo rates on the input side as I show in this video. This is discussed in OpenTX University in the helicopter setup section: open-txu.org/home/special-interests/helicopter/heli-part-1-setup/ It specifically states: "Dual Rates and Expo - Next step is to change DR and expo for the Aileron, Elevator and Rudder. This could be done in the mixes, but the best place is in the inputs. The reason for this is that if CCPM were ever to be used, the CCPM mixing is done directly from the inputs, not the mixes.
@@Rchelicopterfun Craig Oakley mentioned in part "CCPM for Taranis": You may also notice I have NoTrim for the collective inputs. This prevents any trim entered by the trim added through the throttle trim tab from affecting collective. I also do the same for throttle. This will come in more important in the lesson on internal combustion (Nitro) helicopter setup.
Yes, I totally forgot about the throttle stick trim issue (it's been 4 years since I converted the entire fleet over to OpenTX). On my one remaining nitro heli, I use the same throttle servo/idle control method I show in that gas airplane video with the idle control S1 dial add multiplex function on the CH1 (the throttle channel) mix side so it has no effect the collective output when using it. I just looked in my radio at that model, and the trim box is also turned off on throttle stick input setup screen so it doesn't impact collective output if I accidently use trim on that stick. I never touch that trim no matter what I fly, so I guess I pretty much forgot about it - out of mind out of sight kinda thing - lol.
Just cut it from a thin piece of cardboard, but any similar material will work. It's covered in chapter 3 (micro cp setup) of the setup & tips for collective pitch RC helicopters if you have that eBook already: www.rchelicopterfun.com/rc-helicopter-tips.html
John, Could u pls make a video of doing HANDS OFF hover of XK helis? The manual or other's video on it is not clear at all. Also, how can I make my CYCLICK reponse STICKY for slow scale type flying. Right now my default settings is twichy 😡😡😡😡😡☹️☹️☹️ Thanks . I alys watch yr vids.
I'm presuming by "hands off" you are referencing "auto level" or as XK's marketing calls it, 6G? If so, I go over that in the video when talking about the output of Chanel 5. Ch5 travel output in one direction activates accelerometer stabilization, in the other, normal gyro stabilization. I also explain how to confirm it's either turned on or off by watching the swashplate behavior since XK's heli don't show it by LED color like some other brands do. Of course there is really no such thing as a long duration "hands off hover" with any single rotor micro CP heli; you still have make corrections regardless as hover equilibrium is easily disturbed by even the lightest breeze or the little heli flying into its own dirty air. As for cyclic response to be more scale like, just keep dialing down your cyclic dual rate values until you get them to a point where you feel you have a good compromise between control and reaction/response speed. Keep in mind however there is only so much that can be done with small micros that have next to no mass. Micro's will never have the awesome fluid flight characteristics and rock solid feel of a larger CP heli that is required to mimic scale helicopter behavior.
@@Rchelicopterfun , U made a video of XK 123 and 124 taking into CALIBRATION mode, but one did not go due to unknown reason. Yes 👍 I meant HANDS OFF hover in 6G mode, at least couple of seconds.

Wow. You are my new go-to source for my RC heli hobby. I consider myself an intermediate pilot but your content is absolutely invaluable for everyone and I’ve already learned key info. I own a few of the helis you’ve covered and I’m very excited to raise my game thanks to you. Ive followed several online / TH-cam sources with only a very select few actually useful & easy to follow. I’ll be purchasing your ebook without second thoughts. You have raised the bar big time. Good work!!
Thanks for the kind feedback. Glad you found my content helpful.
Even though I have yet to move to Open TX, I now understand basic setup for micro helicopters. ALL your videos have taught me something of value. I can set up all my XK, Eachine and Yu Xiang helicopters in the Xk X6 controller perfectly. Even the Spektrum DX6E benefits from your teachings. Thanks again. PS: I can hover and move around a lil better in agility mode now. And I am breaking less parts, 😂.
I really enjoy watching your videos over and over. Your explanations are clear, precise, and thorough. I especially like the way you explain the basics of RC helicopter transmitter setup. john if I said this once I'll say it again. I really enjoy watching your vids over and over, I also like the fact that you also go back over the steps to recap.. recently got the radiomaster tx16s, watching your video on the goosky and omp, made a tough decision, Got the goosky s2 cause I really liked the ease of battery replacement..
Thanks and enjoy your S2. I know you will 🙂👍
ALWAYS know I’m getting the definitive word when I read your e-books or follow your videos. Special thanks for staying out of FULL GEEK MODE when describing OpenTX setup. I’m gonna HOLD my breath till you make “the next video” on setting up an eCCPM flybar Heli in OpenTX ;-) Thanks again for these tremendously helpful videos.
you make a very good class for these set up!! Thanks a Lot
Thanks John, just what I needed , brilliant explanation of setup, worked first time, great job and top knowledge, I've just gone from dsm to opentx due to flying drones and then realised I need to setup my heli, I'm a happy man :)
Glad it helped
First!
Oh and I was one of the people who was begging for this particular video - A++++++ :D
Thank you so very much John this was extremely helpful!
Awesome vid John, well explained without going too crazy with open-tx details.
Glad you liked it
I wish I'd seen this video or one like it before I first-flight-crashed my Eachine E160. With the default setup on the E6 radio, when I brought the throttle/collective down quickly, the resulting negative collective slammed it into the ground, breaking the landing gear and swash-plate links. While waiting for the replacement parts, I edited the collective points upward at the low end (after writing down the original).
Hi Thanks for the very informative video. I am new to opentx and having difficulty in binding nano CPX and Nano CPS on my Radio Maser TX16s. I've had no problems with WL toys programing and binding. Any help would be greatly appreciated . Thanks
Thanks John !
thank you for watching 🙂
I just programmed my first flybarless. Model using companion wizard and choosing airplane which gives the first 4 channels. Added channel 5 and 6 for gyro and collective. Love the flexibility of open tx. Flying the model on accurc sim on x9 lite. Waiting for delivery multi. Module for spektrum and futaba
. My flight modes only change the throttle percentage. Use the same linear curve for pitch . Added a mix for gyro by assigning pot switch to add or subtract the gyro value to fine tune tail gyro on newly built model.
Hi John, thanks for the Video, I followed these instructions on an XK K110 today it found it really nice to fly. I also tried it on an E160 and I’ll give that a try tomorrow.
Hello Daniel, can you share your settings for scale and 3d flying on the x6 for the k110s?
It took me awhile until I found your videos. Great each one of then. Do you have any video or references on how to setup K123 on OpenTX and how to adjust the pitch like you did on this K110 video? Thank you and congratulations on your excellent videos.
How do I fix my RC helicopter the light is blanky on the four in one receiver
As always, thanks for a great video!
Noob alert questions:
1) In normal mode 0 to +8 collective; how do you land the helicopter if it doesn’t have negative collective?
2) Why is it called dual rates when there are more than two rates?
1. Why and physics are covered in detail in my setup and tips eBook: www.rchelicopterfun.com/rc-helicopter-tips.html
But the primary reason is gravity.
2. Because all radios used to only have 2 position toggles for that function (thus dual) and the traditional name has stuck even with tri position toggles.
@@Rchelicopterfun Thanks again! Much appreciated. I just ordered the Combo 3 eBook package five minutes ago. Looking forward to reading them!
Appreciate the patronage - happy flights 🙂
I have a question on omp m1, the wires came out of the plug for the tail motor, the black wire still connected to the end socket, I need to know where the blue and red go, if I know the middle wire that would be enough. How can I wire to a new connector, what do I need, ythank you, your help will be much appreciated
Hi John,
Why don't u make a video about RotorFlight, a revolution in helicopter FBL unit. Hope u would come up with tht
I'm not a Rotor Flight user. I fly Bavarian Demon and Ikon mostly plus it's a big time investment in learning, getting used to and fully trusting a new system. With that said, I'm interested in trying the new RadioMaster Nexus which as you likely know runs on RotorFlight, but it at least has been properly tested and tuned by others as I have no time nor desire to beta-test open-source unknowns, so we will see what the future holds. Jonas of course has already done a full Nexus configuration video which I can't hold a candle to.
Amazing videos.. Thanks for walking the clueless through this in a clear manner
Glad you found it helpful
Great video, very informative. Thank You!
Glad it was helpful
Great video very informative, my xk k110 drifts to the left pretty aggressively right out of the box. seems like 50% trim to the right helped but it still wants to pull to the left, I have to stay on the stick and give it constant input to the right even after I calibrated it in 6g mode several times because I don’t know how to fly 3d just yet, does it sound like I may have a defective helicopter?
Check and level the swashplate to see if that helps (a little right tilt to the swash is okay to counter the left tail rotor translating tendency - just a smidge. Have you even tried it without the artificial self-level help turn on (ie normal 3 gyro mode)? If it is fine in normal 3 gyro mode, but drifts with the accelerometers turned on, and if you can't successfully calibrate them, then yes, that sounds like a defect issue (if you have confirmed the swashplate is level). With all that said, a nice tame learning to hover/fly setup in normal 3 gyro mode will be almost as easy to fly as if the 6G (self level help) is turned on, and you'll be learning the real feel right off the bat so you won't have to relearn it all over again when you turn self level help off. But do check the swash level since that is key to having a well trimmed bird off the bench.
John Salt thank you so much for your reply I really appreciate it, I’ll give 3D a go next flight and hopefully it doesn’t pull to the left in that mode.
Thanks so much for this video. I just bought this heli and using your setups make it fly very stable. My only issue is I require a lot of right trim to get the heli to stop drifting. So in my case the swashplate is tilted right. I’m new to this so pardon my ignorance. Is it ok to use digital trims on a flybarless heli? If not, how can I get swashplate back to level and not have drift? Thanks
@Mark Linder - you have to mechanically level the swash by pushrod adjustment. Radio trim on FBL should never be used. Some FBL systems without mechanical servo to swash pushrod adjustment (ie. fixed length servo to swash pushrods) will generally have FBL internal servo trim programming to individually adjust each of the 3 eCCPM swash servos to level the arms and get a level swash, but the K110 requires mechanical leveling.
Great tutorial. Thx
Glad it was helpful
@@Rchelicopterfun by any chance. How to switch to stab mode and calibrate gyro and accellerometers? Thanks!
Great video!! Thank you so much! I have flown RC airplanes and drones
And now I am mounting a TREX 470LP. I am new in helicopters.... is there any placer where I could take an OpenTX configuration for such model? My radio is a Jumper T16 with OpenTX. Thanks!!
As I say in the video, OpenTX university is where I got all my configuration ideas.
is this work if my tx16s is elrs protocols and run open tx?
Yes.
Very interesting and useful. I have already bind a E119 in a Radiomaster TX16S using the layout for heli that is already in the radio, but it is for a CP model. The question is, how do you adjust this profile for a FP heli? Best regards
No pitch or throttle curves.
@@Rchelicopterfun Thks John, it worked flawlessly. Now, how do you untame this heli. In the original transmitter there is a button to make it fly more agile. Regards
Hi John. Nice video showing all your settings (inputs, mixes and outputs). I wonder if you would recommend this setup for the eachine e160?
I follow the exact same process for ALL collective pitch helicopters.
I have an e160 that I’ve been really struggling with and used these same settings (instead of the 3D ones all over you tube) and now am able to actually fly it a bit. I’m still a complete learner but couldn’t even hover it with the other settings.
Set my Fusion 270 up with OTU. Everything work except the motor won't come on. It did with another Tx, but not with my QX7S. It's something in TX setup, but I can't figure it out. Any suggestions?
Look at your channel output monitor and see if you have throttle output on your assigned throttle channel. If not, then you have to start digging through your OpenTx configuration. There are so many ways to alter the outputs on OpenTX after all. Might be something as simple as not low enough throttle signal to arm the esc or throttle signal is backwards. Lots of other possibilities of course.
John, great video, very illustrative. I just set an XK K110 micro heli, following your video. It is already flying, but I have a concern regarding the throtlle. In normal mode, the heli starts spinning at around 40% travel of the stick. How do I fix it? Regards
No idea, I would have see it in person.
Hey John, finally received not one, but two TX16S transmitters (I thought I had damaged the first one accidentally but I had bad batteries). Now I need to figure out what receivers. Have you got any guidance on selecting one? I’ve got 4 helis waiting to fly including esky f150, eachine E160, Fireball Havok, and OMP M2V2. I also want to get a 700-800 size once I master these too. Every rx I find seems to be geared towards FPV/multirotor. Thanks again for the great videos!
I would first determine which flybarless system you are getting for a larger heli and then you will narrow the list knowing which RX compatibility the FBL system requires.
Hi John, love the series with your concise logic, and I'm using this to set up my K110 on my Tango2. Struggling to find enough switches though? Should I add the separate rudder settings into low-high rate switch and use the now free switch for the throttle curves? OH, and another question (sorry). From size and gimbal travel, would you say the x6 & RM tx16s are similar? I wasn't blessed with big hands so wondering whether the TX12 would be better for me? Any input would be great - keep flying :)
If you have limited toggle switches then combining all DR functions on a single toggle makes perfect sense. X6 is smaller than the TX16s and very different. No idea how much smaller the T12 is than the TX16s.
Hey John, how are you doing? I cant't find your video where you set up the throtlle cut. I have a question regarding nitro helis, what switches you use for throtlle hold and throtlle cut? Regards
good day to you, more question, when you are setting up your pitch do you have your transmitter in the idle up position or normal mode.
I cover this process in detail in my Setup & Tips eBook: www.rchelicopterfun.com/rc-helicopter-tips.html
thanks, will check it out.
Thanks. However when and how did you set up the collective pitch? Do you not need to program the cyclic and pitch in the input screen to enable the collective pitch to work? Or did the automatically set up because you selected the heli mode?
Not sure I understand your question "setup the collective pitch." Collective pitch setup starts at 17:06. If you are asking about an eCCPM (electronic-cyclic-collective-pitch-mixing) setup, like almost all flybarless RC helicopters, the K110's flybarless system (flight controller if you prefer) does the 120 degree 3 servo eCCPM mixing internally. There is no radio eCCPM mixing required. Just that you setup your collective channel output (ch 6 in this case) with your various pitch curves.
Only if had a heli that didn't do the swash mixing via the flybarless system (Align 3G or 3GX for example) or any flybared 120 degree eCCPM heli, would you have to enable internal radio eCCPM mixing, and that would be done in the heli setup menu on the radio to select an internal radio eCCPM swash mix program.
@@Rchelicopterfun thanks, you've answered my question.
Question, how do you know which channel is the throttle channel? Or does it not matter? I think it would. I'm trying to setup an eachine e150 on the radiomaster tx16s. I want to do it properly.
Thanks,
Dennis
Futaba channel mapping order (AETR) - yes it matters.
Thanks for the very informative reviews
I have just received k124 which bound to x6 ok.
A couple of minor bumps and now it's unresponsive.
No bind lights just slow beeps.
Does anyone know what?
flight control board is screwed
I regognized "white" version of K110 (not K110S) has also 2 versions in the controller setup!
Old version throttle can be regulated from -100 to +100. (0 to 100)
Newer version have only from -100 to +40 (0 to 70). From +40 to +100 no increase of throttle.
That is crazy.
Improvements on this heli:
a) GNB 520mah HV LIPO, +0,15 Volt increase the RPM, Lipo fits without issues
b) Change plug to GNB27, 0,05 to 0,1 Volt more efficency
c) Change tail blade to Blade mCPX/2 (need small driller, drilling by hand to open hole 0,1mm)
4 years of K110 experience:
- Number 1 end of lifetime.
- Number 2 not found in deep gras
- Number 3 left in a tree
- Number 4 with black motor
- Number 5 and 6 with purple head on the motor. (since 1 to 1,5 years available)
- Number 4 and the 5/6 fly different.
Now I understand why :)
kind regards Timo
John. What with your experience, passion, ebooks ( i have three) and you tube coverage, we learn all we need to know re Helis.
I just love that Radio!!!.
I have the T16s.
I notice you did not use the HELI icon.
Do we not need this then?
Somebody told me the Heli symbol is only for flybar types but that doesnt sound right. What about swash plate set up?
Do we need HELI for that please?
Peter
@Peter Cane - I'm not sure what "heli icon" you are referencing? If it's the little red circle shown in the model setup screen (a little airplane shown in this video), it really has nothing to do with radio outputs since we are programming those anyway.
You do have to have the "no heli" box unchecked however in the build options so you can activate CCPM swash mixing type for helicopters that require internal radio CCPM mixing.
By the way, flybar or flybarless has no impact on type of CCPM selection, it has to do with where the swash mixing occurs (externally in the helicopter or internally in the radio system).
You can have external swashplate mixing on both flybarless (most of todays FBL systems do the CCMP mixing) or old mechanically mixed flybared helicopters (swash mixing is done on the heli mechanically).
Likewise, you can have internal radio swash mixing with flybared helis that don't use mechanical mixing or some FBL systems like the Align 3G & 3GX that don't do any swash mixing within the units.
I cover all this in two separate videos I made on OpenTX for helicopters.
Part 1 - No radio CCPM mixing (external mix): th-cam.com/video/XdFOndPG7xo/w-d-xo.html
Part 2 - Internal radio CCPM mixing: th-cam.com/video/AaNx-83WJeg/w-d-xo.html
Hope that helps...
@@Rchelicopterfun
Thanks John. Yes that helps a lot.
Yes I mean the H icon in a circle on the Tx menu. Second icon along from the left.
@Peter Cane, the H submenu is used for swash mixing programming. It's only used with internal radio CCPM swash mixing, not external mixing which is why it wasn't used on this K110 heli example since the FBL system in the heli does the CCPM mixing. I cover using that H submenu in that second OpenTX heli video I mentioned above (internal radio CCPM).
@@Rchelicopterfun
Okay John bear with me I am an old noob!!!
I have to set financial limits to my new obsession so I limit t my helis to very small ones.
I have two S3s, an XK K110 in the post and I look forward to getting an OMP Hobby M2 Explore.
So these three already have internal mixing and do not require the H icon but Noheli left unchecked yes?
On the newest open tx SD card firmware version there is no Heli wizard. Is this right?
There are quite a few of us that are experiencing difficulty setting up an S3 with a T16S and most describe it as " Tricky".
I went out and bought a DX6E to do it but its niggling me that I cannot do it with a T16S.
Would you be kind enough to do a vid on this ?
Thanks John for getting back to me.
You deffo know what you are doing so I will copy you.
Making a training skid but I have to think hard where to get the balls.
Thats half the fun.
Peter
@Peter Cane - Sorry, I don't know what a heli setup wizard is on OpenTX? There never was one that I know of since using OpenTX from 2017 onwards. I've always used OpenTX University's base template which is what I show in those two videos and I use it on every collective pitch heli I own from little micros up to 820 size turbine.
The Nano S3 would be setup identically as well. I don't have an S3 to do a video on one, but again, it would be identical to any other collective pitch helicopter setup. The only difference with it over this K110 example would be it uses Spektrum channel mapping order (TAER) instead of Futaba order (AETR). I even go over that in the second video above where I discuss creating additional OpenTX templates (4 in total) so you are covered for both Spektrum & Futaba channel mapping for both external & internal CCPM.
As you'll see in that first OpenTX for helis video (external radio mixing), you don't necessarily have to uncheck no heli in the build options if you are only going to have/setup/fly externally mixed CCPM RC helicopters (such as all the ones you have listed). All the no heli box option does is remove that swash mix sub-menu from the list. However & as I point out in that first video, it's generally in your best interest to have that swashplate mix menu in your base heli template for if/when you may get a heli/s that require internal radio swash mixing. In other words, it somewhat future proofs your base OpenTX heli template.
John, I might be wrong, but it seems to me that at minute 23:46 the curve PtN might have aprox 9 degrees at the upper stick position as you said, but at midstick it is not zero degrees. Zero degrees are attained only at the low stick position and pitch increases to 9 degrees at upper stick position. Regards.
Yep, a misspoken blunder on my part. The collective range in that example pitch curve is 0 degrees at low stick, about +4.5 at mid, and +9 at high.
@@Rchelicopterfun John, I am trying to understand why you use that curve, instead of keeping zero degrees at midstick, similar to idle up 1 and 2
Simple, much tamer flying in that 1st mode. All covered in my setup & tips ebook: www.rchelicopterfun.com/rc-helicopter-tips.html

Thanks for the video. Would you consider the Blade 150 a micro helicopter and set it up in the configuration outlined in this video?
Yep! Anything under a 200 size machine I consider micro. Regardless, CP setup is setup. I setup my 700 & 800 size machines not much differently than my micro sizes for various flying styles.
Thank you.
The esc you have in the helicopter, is it necessary? Does it prevent the angine from overheating and destroying?
The ESC is what controls the speed of the both main & tail motors; so yes, it's 100% necessary.
hey John your expo is + like spektrum should futuba be - expo?
Opentx uses positive expo to shallow out the output just like JR/spektrum. Not like Futaba.
thank you sir! good to know!
Hi John, I thought I heard you say in one of your XK review videos, that this eBook was free. Did I misunderstand you? Thanks.
Never said that...
At 100 duel rates on cyclic, my servos end points run out before my stick movement does, can I use outputs to match them up?
It depends on the flybarless system. With most higher end FBL systems you set the max cyclic travel in the FBL unit. Other basic FBL units, yes, you can limit the travel outputs in the radio for the cyclic travel on pitch & roll channels (elevator & aileron).
@@Rchelicopterfun thanks John. So this is with the OMP explore. I've had to order the M2V2 as I could not fix the issue with the explores tail not holding and blowing through motors. Disappointing but hoping for better luck with the new one.
Hi jhon...
how many mm of paper size is used to measure?
When you went to create a new model for this Heli it brought up a menu on the side that said 3D helis along with other ones but on my TX16S transmitter with open TX with the newest firmware downloaded when I go to create a model it only pops up a menu saying glider or airplane as the only options it gives me. Am I missing something? I cannot figure out how to choose helicopter or 3D helis or anything like that.
I simply created those extra categories (same thing as creating extra file folders). In openTX in the select model menu, there are 6 options: Create model, duplicate model, move model, create category, rename category, delete category. It's that simple.
Another question, John. I see you adjust the collective range (24 degrees) in the outputs (ch. 6). But I thought the pitch curves was setting the collective range? Obviously not. Do you have a short answer to my misunderstanding?
Pitch curves set your individual collective ranges for your different flight modes, what I'm doing initially with the +/-12 collective is setting the maximum possible collective range the helicopter can produce.
Where did you get the models for your radio?
Is there an open Tx repository?
As I state and demo in the video, I first created two generic heli models (3 if you included the generic Futaba model with ch3 throttle). These 3 generic models are the base foundation for my inputs, mixes, outputs & curves. After that, every new heli model I enter, I will use one of those three models by duplicating it. I then select the model, name it, attach an image file, and go through all the setup steps along with creating logical functions and telemetry setup for the larger birds. In short, every model I have listed in the radio, I created & customized myself, but every one of them is based on one of the 2 generic collective pitch model foundations I first created. It took me over 6 months to slowly switch all my helicopters over to OpenTX & FrSky when I made the switch from JR/Spektrum. Yes, it's a massive undertaking switching systems. I hope I never have to do it again, but in this hobby, that would be unheard of.
Dear john, maybe you can help me.... I also have xk130 that i bought year ago and just sitting in my garage cause it doesn't fly good.... The problem is that when ever arm it, the swash plate on the right side tilts up.... I have setup all flat and nice but everytime arm to fly it tilts so on hover blades are tilt in steady hover... I have replaced theain board and still same..... Help me please...
I would really have to see it first hand to correctly diagnose; but it sounds like the servo arm on the servo in question has likely cammed out one or perhaps more spline places on the servo output shaft. A servo gear could also be stripped in that servo causing it to jump out of position. Just guess of course without seeing it first hand.
Hi John, Correct me if I'm wrong. Setting up my XK-110 with my Jumper T16, I found the Throttle and Pitch hold switch (SH) would not work since it is a toggle switch. I choose (SF) switch, a two position switch and the heli will not spool up in hold mode now. Everything else worked as you explained. Respectfully, Barrett
Howdy Barrett. Yes, I physically swapped my rear toggle switches around so the sprung momentary is on the left and the normal two position on the right (like I'm used to all on my previous radios over the past 30 years). So what you did there by using the SF toggle on the left for your throttle hold activation is spot on correct.
The next statement however "the heli will not spool up in hold mode now"... I don't see any problem with since that is the whole idea of having throttle hold turned on - the heli won't power up when hold is engaged. So I need clarification on that because it's working exactly the way it should. If something isn't working correctly however, use your channel monitor screen to help fault trace. As I so often say, it's one of the most important tools that computerized radios give us to help figure programming issues out.
@@Rchelicopterfun Thanks for the quick response John. No issues with function of hold mode. I could have stated that better about the spooling. Thanks for clarification. Respectfully, Barrett
Awesome 👍

Awesome video, John ... as always! Thank you! I set up my K110 with all your settings, but you don't explain HOW to setup the gyro gain/values. I tried to copy your setup but I don't think it's working. The switch indicates it's going from -100 to 0 to 100, but I can't confirm the model is switching/entering the two modes properly (don't want to do a test flight until I KNOW it's working PROPERLY). The method you showed in the video doesn't seem to work on my model. Shouldn't a LIGHT on the board CHANGE when you're in 3D vs. 6G??? My lights stay the same (red and blue both on solid). Also, my two aileron servos are not centred/level (no idea WHY). The one is slightly low and the other is slightly high. Sooo, the swash is not level side-to-side. HOW do you level them? I've leveled legacy helis in the past using sub-trims, but I have NO IDEA how to do it on a micro with a flight controller. Do you adjust the aileron mid-point or something???
@TechNoPhobia - There are no remote gain adjustments on the K110. Like most modern day micro size FBL collective pitch RC helicopters, channel 5 only controls the mode of stabilization. Either normal 3 axis gyro mode selected, or self level mode activated. Basically a this or that selection with anything from about 0% to -100% travel output putting it in one mode, 0% to +100% travel output in the other mode. *No gain adjustment at all.*
There is no LED color change or flash sequence on any of the XK helicopters to indicate which stabilization mode you have selected. However, like any FBL unit that also has a self level mode, it's pretty easy to visually determine by swashplate tilt behavior what mode is selected. In self level, the swash will generally stay tilted after a cyclic command or heli movement. Whereas in normal gyro mode, the swash will slowly level back out after a cyclic command or heli movement. Or just hover the thing to feel what stabilization mode it's in as it's pretty obvious. 🙂
If you are not getting a mode change by channel 5 activation, you'll have to confirm on your radio (servo/channel output monitor screen) you are getting full channel 5 travel in both directions with whatever toggle/activation method you have selected to control channel 5. If you are not seeing any channel 5 control, you'll have to recheck your channel 5 input/mix/output programming setup.
I know of know way to electronically level the servo arms on the XK micro helis. I've always made adjustments mechanically if required to trim them out (in normal gyro mode). Mechanical adjustment procedure is the same as it is on any RC heli... first servo arm spline selection to get the arm as close as possible to a level position, then pushrod ball link threading adjustment to level the swash.
@@Rchelicopterfun Wow! Thx a million for the QUICK, detailed reply! My swash doesn't react like yours in the vid to indicate EITHER gyro mode. When I tilt the heli, the swash stays put (maybe I'm not 'doing it right'???). I'm using the SB switch and, yes, channel 5 is indicating -100, 0, 100 output in the monitor. Dunno what I've done wrong. I don't want to do a test flight because I CAN NOT fly without stabilization. Period! I'm used to fly bar helis that 'self-level' (in normal flight mode, I guess) when the cyclic stick is centred. These FBL helis that stay in one position when the stick is centred are beyond my control! I just crashed my brand new E160 when I switched it into 3D cuz I couldn't friggin' KEEP it level. It was BONKERS! I also had 100% travel and no EXPO tho, which was an oversight in the heat of the moment! If I'd reduced the travel, I MIGHT have regained control. We'll NEVER KNOW!
@@Rchelicopterfun So I flew my K110 last night and everything seemed to be OK ... sort of. Didn't have enough collective range so the bird didn't want to climb, especially in normal mode. Increased that and it was MUCH better. As far as the tail goes: NOT enough gain! There HAS TO BE a way to increase the gain on the gyro using OpenTX! Using the XK X6 radio, the tail is LOCKED IN ... BEAUTIFUL! Using the TX16S, the tail is pretty bad. I noticed it RIGHT AWAY! Even just taking off, the tail was drifting left, which it NEVER did using the X6. The X6 gains are set at 75 and 25 FOR A REASON. They're not set at 0 and 100. Using the TX16S, the gains are set at 0 and 100, effectively. There has to be a way to set them at 25, 75 using OpenTX. I'm REALLY surprised you said in your review that the tail was "locked in" using OpenTX; that certainly wasn't the case in MY experience. In fact, the tail was SO NOT locked in that I immediately considered going back to the X6 radio to fly THAT model. I totally trust and respect your advice/opinions, but my experience was totally different than yours with this model. I'm probably doing something wrong.
Hi...jhon
I want to ask
What is the setting for the micro heli, can you use the heli size 200?
Thank's
I don't understand what you are asking about "setting". What setting? If you are referencing collective pitch RC helicopter setup, size of the helicopter is irrelevant. You setup a collective pitch RC helicopter to produce the amount of performance you want out of it based on how you want it to behave & your flying style/experience level. As I say in the video - that is the fundamental constant for all collective pitch RC helicopters regardless of size, brand, or power type.
www.rchelicopterfun.com/rc-helicopter-tips.html
Can I set it up "tame " with the radio that comes with the Eachine E160 RTF
Yes you can. That's why computerized radios are so important, so you can setup any CP heli correctly & to suit your skill level & flying style.
Great video, I don’t know if you can help but is there any way I can turn off the safe mode on my Blade nano CPS. I’m using a dx6i.
I can turn it off in idle up with the gyro switch, but I can’t get it to turn off in the first mode.
I just want the first mode to be similar to the factory set up but without SAFE.
I can’t work it out.
Like most micro helis, the Nano CPS SAFE (auto level stabilization) is activated and deactivated through channel 5 output (just like it is on this little XK K110). I believe in the Nano instruction manual for programming, they suggest mixing the channel 5 output to the flight mode toggle so your flight mode toggle is what turns SAFE mode on. If you don't want that function, then you would have to turn that mix off and have channel 5 control through the gear toggle instead.
John Salt ok thanks that’s great. I will have a look and see if I can work that out.
John, just to understand the way you fly. Do you use three switches to set the flight conditions: the rate/expo of aileron/elevator (SD), rate/expo of rudder (SG) and flight mode (SE)? Regards
Pretty much. Like most traditional collective pitch RC heli setups, I use a 3 position toggle to set my 3 separate pitch and throttle curves for my 3 flight modes (plus a separate hold throttle & pitch curve) which naturally overrides any of the others when I engage throttle hold.
As for dual & expo rates, I personally like having a separate cyclic dual rate toggle and rudder dual rate toggle and use two more toggles for them. With OpenTX (and most other computerized radio OS systems), all the dual rates could of course be coupled to the same toggle as the flight modes so it's all controlled from a single toggle for those that find that easier. I just like having the ability to separate my dual & expo selection from my pitch & throttle curve selection, especially for scale or F3C type flying.
@@Rchelicopterfun Thks, John, great explanation. I was wondering about using the potential of Open TX, but you explained it very well. Regards
very valuable video, any link of k110 model setup file for download Pls?
Sorry, I don't share my files. Why?
#1 & main reason... It would not be fair to all my customers / students who paid for my collective pitch setup & tips ebook along with my my setup help & instruction over the years. They are the reason this channel even exists.
2. It doesn't teach people a thing about how to properly setup a collective pitch RC helicopter or use OpenTX.
3. It's a huge hassle then trying to explain how my specific settings work and why I configure my radios the way I do.
4. I know exactly what happens because I have tried it for a few people just to see how it would play out. People just used the settings unaltered even though I warned them about that. Not a single one confirmed the mechanical setup of their heli first, and then adjusted the outputs accordingly so the collective range and the symmetry of their collective range would then be correct for proper pitch angle. These are not mechanically simplistic quad copters after all; every single collective pitch RC helicopter has mechanical variation - even the exact same RTF models.
The result of all this... A crash on first spool up, and I get blamed for it because they didn't understand the basics of collective pitch setup. Never again.
John, I notice in minute 17:22 that there is no switch assign with ThN, is it correct? Regards
Good eye! It was my mistake. I must have deleted that specific switch position by accident as it was in there initially. It still works fine of course since there is no other switch option there so in normal mode, it just defaults to the normal throttle curve. But yes, it should have shown the SE toggle with arrow pointed up just as it shows for channel 6 normal pitch curve selection 6 lines below.
@@Rchelicopterfun Thks.
hi john so great that you have done this, i also asked you for this on your k110 video as i have a jumper t16 and a k110 so open tx is similar in layout beteen the t16 and the horus. This is very cheeky but could you upload this setup for the k110 for download, i would be very grateful

One question, if you don’t mind
On minute 10:05, on the radio screen (first setting) you have as channel 1 thr, is that correct? If so, what settings do you have in that channel?
At that time index (10:05) I'm actually setting the inputs (what stick or switch is assigned to what function). It really makes no difference what order you create your inputs as it has no bearing on channel mapping. I just use the order I'm most familiar with (TAER). Setting your mixing in OpenTX is where you assign your inputs to a specific channel. I go over mixer settings (what channel you map your inputs to starting at time index 14:44. In this particular example as I explain at the beginning due to Futaba's AETR channel mapping (which this specific K110 heli uses), I have throttle assigned to channel 3.
John, you show the values on the Horus, but have you programmed all that on a pc first, then loaded the open tx model to the radio? I assume you don't program on the radio, right? Thx
I perform all radio programming for all my models with the radio alone. That is the benefit after all of a computerized radio - direct programming without the hassle & complexities of external devices. 🙂

Nose-in orientation doesn't change a thing on the heli, so no idea there other than normal lean caused by tail rotor translating tendency that perhaps you don't notice as much when it's pointing tail in.

John, at minute 13:55 I notice that your toggle switch SG moves in the opposite direction than switch SD to choose from 100 and 50% dual rate. Is there a reason for that? Regards
It just my preferred method of toggle position when I'm in low or high rates. In low I want my upper toggle (SG) to be in the rearward position and my front toggle (SD) to be in the down position.
@@Rchelicopterfun Ok, thank you again for your patience. You relay very much in your memory to remember that!!! For me, it would be simpler to uniform the action of all switches. Regards
Back in the day before computerized radio', all dual rates selections were default to those positions that I use. That subconscious memory after close to 40 years of RC flying is not easy to change - why it makes sense to me. Of course, that is the beauty & power of computerized radios, we can configure them any way we want.
Hi John. Can I use this setup for Ikon flight controller?
This video addressed the radio and helicopter setup portion of RC helicopter setup. That is different from the flybarless system configuration & setup. Regardless of what flybarless unit is used or even if it's a mechanically stabilized helicopter (flybar), collective pitch RC helicopter is very much universal and all these same steps I show with this little micro CP heli are done with all sizes. As for flybarless system setup & configuration (RX connectivity type, servo travels, centering, pulse width, gains, travel limits, gyro direction, swash leveling, piro-comp, etc.), that is unique to each flybarless system and the best tool you have for that is the flybarless system's setup wizard.
Thanks for the help.
Hi, John. I am wondering if with the new wave of transmitters in the market someone has set openTX v 2.3.10 for a heli with this features: nitro, CCPM 120 (requires command directly to the servos, not thru gyro), expos and throttle trim on.
For now, I was able to adapt CCPM configuration for the Taranis (that is in the OpenTx university) in a MiniTitan, but I think there are still some missing issues to fully exploit the new transmitter, the way a simple Futaba 7C can be configured to fulfill the configuration of a nitro heli as described above.
Yes OpenTX can control a normal eCCPM heli. It will allow 120 degree mixing within the radio for traditional flybared machines or ones using flybarless systems that don't do the 120 mixing internally. Now I'm still running 2.3.9 but there is no reasons things will have changed in 2.3.10. They haven't changed yet in countless updates after all. I won't of course know for 100% sure until I update, and I always wait a good month or two before doing that in the off chance there is a bug in the new release.
I have several fly-bared machines with 120 eCCPM and several more that use Align's 3G & 3GX flybarless systems (electric & nitro) - all working fine with OpenTX . You of course have to make sure you have the heli option enabled in the Companion build options for the radio so you can select the different swash mix types in that menu.
@@Rchelicopterfun John, thks for your fast answer. I indeed watched your video regarding throttle trim with much interest. I am not quite satisfied with the way it tries to solve the problem, mostly because it would still affect channel 6 in pitch control. Regards
Not sure what is lacking or how it would effect CH 6's mixing outputs? Everything works perfectly as it should on all my 120 degree eCCPM mixed helis in OpenTX, just as they did when I was flying them with pre-configured computerized radios.
One crucial & important item however is to make sure you set your dual & expo rates on the input side as I show in this video. This is discussed in OpenTX University in the helicopter setup section: open-txu.org/home/special-interests/helicopter/heli-part-1-setup/
It specifically states:
"Dual Rates and Expo - Next step is to change DR and expo for the Aileron, Elevator and Rudder. This could be done in the mixes, but the best place is in the inputs. The reason for this is that if CCPM were ever to be used, the CCPM mixing is done directly from the inputs, not the mixes.
@@Rchelicopterfun Craig Oakley mentioned in part "CCPM for Taranis": You may also notice I have NoTrim for the collective inputs. This prevents any trim entered by the trim added through the throttle trim tab from affecting collective. I also do the same for throttle. This will come in more important in the lesson on internal combustion (Nitro) helicopter setup.
Yes, I totally forgot about the throttle stick trim issue (it's been 4 years since I converted the entire fleet over to OpenTX). On my one remaining nitro heli, I use the same throttle servo/idle control method I show in that gas airplane video with the idle control S1 dial add multiplex function on the CH1 (the throttle channel) mix side so it has no effect the collective output when using it.
I just looked in my radio at that model, and the trim box is also turned off on throttle stick input setup screen so it doesn't impact collective output if I accidently use trim on that stick. I never touch that trim no matter what I fly, so I guess I pretty much forgot about it - out of mind out of sight kinda thing - lol.

Just cut it from a thin piece of cardboard, but any similar material will work. It's covered in chapter 3 (micro cp setup) of the setup & tips for collective pitch RC helicopters if you have that eBook already: www.rchelicopterfun.com/rc-helicopter-tips.html

John,
Could u pls make a video of doing HANDS OFF hover of XK helis? The manual or other's video on it is not clear at all.
Also, how can I make my CYCLICK reponse STICKY for slow scale type flying. Right now my default settings is twichy 😡😡😡😡😡☹️☹️☹️
Thanks . I alys watch yr vids.
I'm presuming by "hands off" you are referencing "auto level" or as XK's marketing calls it, 6G? If so, I go over that in the video when talking about the output of Chanel 5. Ch5 travel output in one direction activates accelerometer stabilization, in the other, normal gyro stabilization. I also explain how to confirm it's either turned on or off by watching the swashplate behavior since XK's heli don't show it by LED color like some other brands do.
Of course there is really no such thing as a long duration "hands off hover" with any single rotor micro CP heli; you still have make corrections regardless as hover equilibrium is easily disturbed by even the lightest breeze or the little heli flying into its own dirty air.
As for cyclic response to be more scale like, just keep dialing down your cyclic dual rate values until you get them to a point where you feel you have a good compromise between control and reaction/response speed. Keep in mind however there is only so much that can be done with small micros that have next to no mass. Micro's will never have the awesome fluid flight characteristics and rock solid feel of a larger CP heli that is required to mimic scale helicopter behavior.
