- UPDATE: This was a great starter aircraft but I sold it after it taught me all it could. My go-to is now the Turbo Timber Evolution. Very easy to fly and has a much better landing gear and battery tray.
Intro: Detailed information on my Rate/Expo and Mix settings for the Carbon Club S2 and Spektrum NX 8 transmitter. Also some tips, tricks, repairs, and tweaks.
The settings included in the description below assume that you have either imported the correct BNF template or created a new model from scratch and have binding done. It also assumes a working knowledge of navigating the NX 8 menus and options using the scroll wheel.
If not already done first go to System Setup from the main Function List menu. In System Setup go to Channel Assign. Gear = E, AUX2 = F. This assigns flaps to Switch F. The E channel is actually used for Flight Mode selection even though the Digital Switch Setup screen shows it is used for landing gear.
Still in System Setup go to System Settings, Next, Volume Controls, Select Analog (the last option on the Voice Volume Control page) and set to R Knob. That allows the use of the R Knob to set the level for all system sounds. You can also change the relative level of all sound categories on this page. I left them all at 50.
Now go back the main Function List menu.
My Switch Assignments and Positions are:
D: Throttle Cut On=1 and 2, Off= 0
E: Beginner Mode=0, Intermediate Mode=1. Experienced Mode=2
H: Flaps Up=0, Takeoff Flaps=1, Landing Flaps=2
R Knob = Volume Control (as already explained above)
Setup:
Servo Travel: All 100 except AX2 High=120
D/R & Expo (all can be tweaked but the focus is on Experienced Mode):
Beginner Mode Intermediate Mode Experienced Mode
------------------------- -------------------------- ------------------------------
Ailerons: Rate 80 Expo 30 Rate 80 Expo 30 Rate 60 Expo 0
Elevator: Rate 100 Expo 0 Rate 100 Expo 0 Rate 60 Expo 0
Rudder: Rate 80 Expo 30 Rate 80 Expo 30 Rate 60 Expo 0
Throttle Cut:
Switch D, Position 2 = -130%, Position 1 -130% and 0 Unchanged at 0%
Delay = Inh
Require Stick Low = No
Throttle Curve = No change, personal preference
Digital Switch Setup
Switch F: Pos 0 = 100%, 1 = 0%, 2 = -60% (decrease Pos 2 to less than -60 for more flaps deflection)
Mixing: To create a Mix start with a blank (everything = INH), name the control you are changing, then the control to be changed as a result of that change. Example: To move the Rudder when Ailerons are moved the Mix is set to AIL/RUD. Then assign that Mix to a Switch and Switch position.
Flaps - Elevator Mix
AX2/ELE
Assign Switch to F
F = 0: All Values = 0
F = 1: Rate: 0% and -35%, Offset 50%
F = 2: Rate 0% and -45%, Offset = 0%
Aileron - Elevator Mix
AIL/ELE
Assign Switch E and Set Switch E to 2
Rate = -30% and + 30%
Offset = 0%
Do not change Switch E Positions 0 or 1 Settings
Aileron - Rudder Mix
AIL/RUD
Assign Switch E and Set Switch E to 2
Rate = +30% and +30%
Offset = 0%
Do not change Switch E Positions 0 or 1 Settings.
To add switch change audio alerts go to Audio Events, Switch Changes, and set the alerts for switches D, E and F.
Switch D: 0 = Throttle Cut Off, 1 and 2 = Throttle Cut On
Switch E: 0 = Beginner Mode, 1 = Intermediate Mode, 2 = Experienced Mode
Switch F: 0 = Flaps Up, 1 = Takeoff Flaps, 2 = Landing Flaps
Smart ESC telemetry settings: Display = ACT, Total Cells = 3, Low Voltage Alarm = 3.8V/Cell and Alarm = Voice, All other = INH, Status Reports = 60 sec, Alarm Reports = 30 sec

For more basic transmitter settings see this excellent Carbon Cub S2 setup video:
• Horizon Hobby - Carbon...
Note that I have used different switch assignments versus what is shown in the video. It’s just a personal preference.
I strongly suggest you also watch this video.
Footnote: This video was made using an ancient GoPro 5. Apologies for the less-than state-of-the art quality.
As an experienced pilot I can identify how valuable most of this info is - ESPECIALLY the info on cutting the control surfaces off and replacing them with real hinges. Great video sir !
Im new to this and i couldn’t figure out why the servo was chattering on my left aileron. I thought i compressed the screws to much of assembled it wrong. This was very valuable for me.
I have watched hundreds of videos on TH-cam pertaining to both fixed wings and quads which I am an avid pilot with. I am very new to fixed wing flying and your video is by far more understandable than most people's videos and I agree that mr Phillips is also a good teacher..I hope to see more videos from you..thank you for your knowledge
Hoosier TY sooo much for explaining how to use the transmitter while flying in expert mode along with what the plane will do. Out of all the hundreds of rc plane tutorials ive watched no one has even mentioned that whenever you bank right or left the plane will stay banking in that direction (even when you let off and the stick comes back to neutral position) until you move the stick back the opposite way to bring it back to level again. Showing people actually what to do with the transmitter sticks while learning in expert mode is what we all need. You just made expert mode very understandable to me now and im not afraid anymore. Ive been flying in beginner mode alot for the past year so I have a good bit of flight time under my belt. I now have confidence that ill be flying in expert mode this week. Thank you for your wisdom!!!
Very informative video! I just bought this plane, have never flown before, and found this extremely helpful. Especially the differences you described regarding beginner mode vs advanced in regards to the elevators.
Glad you enjoyed it!
Nice video. I have the same plane. I recently semi retired and now have time for RC flying. I built and flew balsa control line planes as a teenager and always wanted to do RC. I still have my last balsa plane although it hasn't flown for 55 years. My Carbon Cub has been through a lot of trauma. I use a waterproof wood glue which works great. Having fun. Thanks.
Thanks for the video Tom, also getting back in after 40 years. Yep, wow the changes! I thank you for the tips - especially on the radio programming on rate/expo - very helpful!!
You are welcome!
Really pleased I spotted this video, some very helpful and informative observations and comments for us less to no experience fliers stepping into the hobby, I'm looking to acquire this very aircraft and it will now be BNF with an NX8 or NX10 for future proof advancement. Thank you for sharing your experiences.
I truly enjoyed your video, especially at the age of 63 and like you coming from old school and now stepping up into the technology part of the hobby. Love my NX8 and my New Maule M7. I'm still flying a older Carbon sport Cub . Red & white without safe. Lol. Enjoy flying and looking forward to see that Maiden of the Xtra 300.
Hello Bill! It's been a real challenge to jump back in. The video is a year old and lots of things have changed. After thinking about it last summer I sold the Xtra to a much more experienced pilot. He is now a friend, and I have seen him do amazing things with it. I just maidened a Maule. The video is on my "channel" if you can call my amateur skills that. You can have a look at what is in the fleet in the end of my Shrike video. This week I'm upgrading 3 of those models to smart ESC technology and the old Turbo Timber is getting a Spektrum AR637T. In the next week or two I'll be replacing the crashed Shrike. The Timber is getting the 637 out of the Shrike. So some good came of that misadventure.
My Cub was sold on eBay at the end of last summer. Just not enough room for it.
Thank you, that was both enjoyable and very informative. Your experience shows through clearly. Thanks again.
Glad it was helpful!
Excellent video!
One suggestion on hardware, it may be WELL worth the time and minimal investment to replace the included screws with socket head types from places like Micro Fasteners and such, and use the proper size socket drivers to tighten stuff.
The socket drivers give a TON'S better feel for tightening everything, as the phillips type screw drivers can quickly wallow out the cheap (I call them "Silver Play Dough") screws that come with the plane...ESPECIALLY if you must often disassemble the plane for transport.
I've replaced all the screws in my Cub and other RTF's with these, and feel they add a great degree of confidence in knowing everything is held together as it should be.
Once again, Great Video and Great Channel!!!
Kim
Thank you very much! Great info! I'm new to the hobby and just purchased a CC S2 (RTF), but have yet to put it in the air. This was very helpful and much appreciated!
Glad it was helpful!
I have tinkered with RC Hobby all of my life with breaks here and there but oddly enough, I’ve never flown airplanes. Growing up my dad was a single engine pilot. I was constantly flying in Cessna 150 I thoroughly understand flight characteristics and I love flying. I actually piloted the real Cessna in a take off and cruising while my dad observed setting next to me. But I’ve only flown drones, RC cars and boats. Deciding which model to get into, I appreciate your video. Suggestions welcomed. I’ve had my eye on the apprentice STS but carbon cub looked good as well.
Thank you.
The Apprentice is a great choice.
I have watched several RC videos for the past month and have learned more watching your one video than all of them together. Most of them fly alot and speak the language but don't show you what they are talking about. Thanks.
Glad to help
Great video, also returning myself after 10 years and using the S2 to re-familiarise myself with everything
Welcome back!
Thank you for the very informative video I love my carbon cub!
Great video in plain language. Liked and subscribed sir!
Thank you Sir! I found this video very helpful.
Great information. Great detail. Thanks.
Very enjoyable and informative to boot. Ive just ordered this airplane package and have no RC or actual flight experience so my aproach at this point is self education, especially sincewestern NY weather isnt the greatest right now to learn in. My experience with airplanes so far is based on Guillows amnd Comet balsa/tissue rubber power. Thank you .
Glad it was helpful!
Very informative video. Thanks. I have the Carbon Cub S+. A couple of things I noticed. You took the strut covers off. I cable tied mine on. They actually strengthen the landing gear. Very important. These planes are made from EPO foam. Not styrofoam. Those wing struts are very important too!
Actually, the wire gear struts are weak and bend at the fuselage. Lesson learned, I don't buy models that don't have steel struts.
I'm in a very similar situation. Been out of the hobby for over a decade and bought the same plane to get back into it. I was surprised to see how fast this plane flies and how much sky it'll use up in a hurry. I wrongly assumed I could fly it in a small park but it really needs some space. I was planning to add the flaps to try and slow it down but your advice on flaps with the included transmitter has me reconsidering. Thanks for your well thought out video.
Flaps are useless without the ability to mix in down elevator. Try it with the DX S and you will regret spending the money.
Go Indy!! Same here. Southside
Great video, very informative.
Thank you Tom for your very thoughtful and informative video. It was very personable, unhurried, and frankly charming. Your suggestions will help me avoid some pitfalls and suboptimal function problems. Since I’ll be using the described hinges for the ailerons, rudder and elevator I may just as well install them on the flaps. My purchase of the same Carbon Cub S2 is pending figuring out just what add ons I want to install. Flaps are a given, but since I am fond of gizmos and gadgetry I’m pondering the GPS and landing assist modules. I really don’t think they are necessary but they are intriguing so I’ll probably spring for them. Too given the readily available electronically independent first person hardware that can be viewed with a Smart phone I might opt for that later. The parts can be ordered from overseas sources for very little money and they are easily moved between models.
Best regards,
Duncan
Duncan, be aware that if you install flaps on any aircraft using those flaps will change pitch. In full scale we have to adjust elevator trim to compensate for pitch changes. In RC we can program a "mix" that adjusts elevator when flap settings are changed. The DX S transmitter that comes with the Carbon Cub RTF version does not have mix programming. I would advise you to either buy the BNF version and a programmable transmitter or not install flaps. My experience was that the pitch changes with Carbon Cub deployment are pretty dramatic. I know, I tried using the DX S and the first time I deployed flaps the model looped! I bought a Spektrum NX 8 and programmed the flap/elevator mix. I later sold the Cub and Dx S transmitter on eBay with a note to the buyer about the flaps. I had moved on to more complex models. As for GPS I bought that too, and found it to be not very useful. If you set up Safe Select it makes landings much easier to learn and landing assist redundant. Good luck with the S2!
good luck with your plane
Thanks, this will help me a lot.
Great information. Thanks.
Glad it was helpful!
Great video Tom!
Thanks!
Great video, and yes I have the same carbon cub, the same as yours. I agree the NX8 is a superior radio to the one I have, the DX6. After getting back into the hobby the changes and technology indeed have changed over the years. If not for the ready to fly planes my reintroduction to flying would not have happened.
I'm in the same boat. I built balsa first time around. With all else going on around here now there is just not time. Besides, it's a lot more fun to fly than build, and these newer planes fly better than anything I ever built.
Great insight, I may have to upgrade my radio at some point. Granted it’s only about a 150 hours in full scale, but I have found that it did not translate at all. The only effect I felt I was prepped for was asymmetric thrust on take off, even adding elevator during a turn freaked me out! I have crashed my Carbon Cub a few times. Thank goodness they’re tough!
Tom thanks you are the best I am 67 you encourage me
I started Rc flying when the pandemic hit and I still fly in beginner mode because I’m not confident enough to fly in the wind or try any stunts. There are no clubs around me nor is there anyone to learn off of so I Thank you for the help. 👍👍🇨🇦👍
Thanks for sharing
Mr. Elam......"Tom" thank you sir for this video. I almost purchased this plane. Not a bad 1st plane...for what I gather...but with your knowledge...I think I will buy a Beaver or something and buy a programable transmitter. I have not joined AMA or my local RC club but I have the "fever"....... lot of fun just shopping around. hehehe..... be safe out there
Great video. I don't like flying in a small plane, (in any plane actually) but I'd be ok if you were piloting it! The tip about expo is great, i.e. it being great for beginners as long as it's not overdone. Also there are so many equipment options and so much partisan opinion out there it's just good to hear someone who knows what they're doing say - hey, this works and you can get it all ready to fly without too much trouble.
Thank you Sir!
You are welcome!
Nice video, but I must say one thing. If anybody does what you mentioned to do with the hinges. They better use wooded toothpicks to push through the wing and holes in the hinges as well as glue these too, and of course, cut to size. Otherwise, if you only glue in the hinges, over time, the glue can come loose and the hinges will come out in mid-flight. I know this because I had it happen with one of my first builds I did some 40 years ago and lost one of my favorite planes because of it. So just be aware of this safety tip as well.
I should have mentioned that detail.
I myself, just getting back to it after about 20-25 year's or so.
This, electric power is what I've been waiting on!
But the batteries and all are something to learn.
I have a Carbon Z Cub SS 2.1 that will be on the back burner till I get better
It’s amazing what has happened. The current smart battery and charger revolution is only a few years old. The digital radios are incredible. So are the outrunner electric motors. In the full scale world the change is almost as fast. Makes it hard for an old guy to keep up. What will the next 10 years bring?
@@GoofballFlyer and I forgot to mention, very good informative video.
Theres a whole list of planes that this dxs transmitter works with. theres alteast 15 planes including a couple EDF Jets and 3 helicopters
=
Great video thankyou Tom. I own a series one horizon ss cub and have done all your mods excepting the mixes. It is by far my favourite plane from my collection and I love how it flies somewhat similar to my full size. How do you find rudder deflection on the series 2? On mine, it was very mild at full deflection and my wings were getting beat up from slow flight tip stalls. I added some length onto the tiny servo control arm and now it can recover from all but the worst tip stalls. It is also more controllable with crosswind ground handling.
Re your flying field problem, I am unhappy with the direction FAA is taking with airspace control with remote id and registration necessary for aircraft as light as this one. It should be legal to fly at sports ovals (not just registered fields) where light posts and trees provide shielding from manned and drone aircraft. An alternative to remote id could be the use of portable adsb receivers for modelists The idea of regulating and controlling what consistantly proves to be the safest area of aviation (rc aircraft and racing drones) is a very expensive one. Much of the price will be paid by us the hobbyists, likely to be to the detriment of our hobby
It does tip stall at the drop of a hat if you get it too slow. I finally started landing it in Safe and with some speed. That worked out great if the grass is short enough. I wonder why the gear is not a little further forward. It flips on its back easier than any of my other planes.
@@GoofballFlyer Ah yes. I forgot about that. The rudder does not stay pretty for very long. We could suggest a few improvements to horizon such as the landing gear further forward. Being a beginner plane, the foam is quite stout and heavy for ease of repair as you say. One disadvantage is the overall weight compared with size which makes for a high wing loading and, consequently, stall speed. (It also flies a little faster than scale as a result.) This also creates the need for a high airspeed when trying to make smooth landings - Quite unlike its full sized counterpart where most normal landings are power idle. This is where its balsa counterparts will really stand out with lower comparative weight and better slow speed perfrormance. Having said that, I would not dare take a delicate balsa model to the park or a rough farm property 🤣
Great video but why did you choose this Cub over other trainers like the apprentice?
Which trainer would you choose today?
I need to get a trainer
Hi Greg
I bought the Cub off a positive review on the RCSaylors channel. Today I might buy it again. If you are flying off grass a tailwheel airplane is the way to go. But most trainers are nosewheel. The EFlite Apprentice S and the Aeroscout are also good trainers but nosewheels on grass can be problematic. There are other brands available but I have not flown any of there trainers. My second airplane was the Conscendo sailplane. I would definitely recommend you get one as you progress but always land it Safe mode. Hope that helps.
So many thanks to you, I'm from Rome, Italy, i fly rc since 10 years or more... With same plane, but only now my wife gift a dx8e, programmable radio, and i have flaps operating.... I try strange when flaps work, nose up... Stall... Your video is very interesting.. i need to ask you: when flaps ar off, it's all ok, but when i switch 1 or 2... Speed must be slow, so slow... Right?? So. Best regards to you.
Yes, that is normal behavior of high wing aircraft. Lowering flaps causes a pitch-up. The amount of pitch-up is also related to airspeed. The faster you go the worse it gets. To fix, you need to mix down elevator and throttle with down flaps. The Carbon Cub S2 instruction manual has the flap installation but not the required flap-mix setting. Your dx8 manual will have general instructions on how mix servo movements. However, it does not have the instruction for this mix. I found a video that explains it. It's for the DX 9, but should work with your DX 6. If you have any more experienced RC pilots available you might want to talk to them too. Here is the video:
www.bing.com/videos/search?q=carbon+cub+s2+dx+8+flaps+elevator+mix&view=detail&mid=B57DA97E0C60686D5E17B57DA97E0C60686D5E17&FORM=VIRE
You may also want to add a throttle-elevator mix, but this is optional and can lead to very bad results if not done properly.
I'm also recently getting back in after several years. No pro flyer here, but I do know a bit about Li-ion batteries from my other pursuits. The nominal voltage of these batteries is 3.7 V per cell. 3.7 times 3 is 11.1 (printed right on the wrapper of your 3s pack). You aren't using more than probably 20% of your capacity. 3.4 volts per cell is where I set the warning, and that gives plenty of extra to make a casual return with no pressure. The threshold you never want to cross is 3.0 volts per cell. Of course, if you drain them less they recharge quicker, but stay up longer and have more fun!
3.2-3.4 still gives you plenty of reserve.
@@GoofballFlyer , right you are, but be aware of the voltage sag under load. If you have to abort a landing, you need power. I have one plane that pushes the battery to >90% of it's rating, and the current draw depresses the voltage a few tenths of a volt.
If you snap the wing spar you might be pulling a little to much G forces.
At those forces it might snap battery strap and eject it out the hatch.
Either way she’s going to plummet earthward in a ignominious end to a beautiful little bird.
I really put her through a lot and nothing major broke, even with the wing struts removed. I don't suggest you try that though!
Tom, In my quest to set up a HobbyZone CarbonCub I viewed your very well done video. All the best. Pat Willcox AMA 262
Cool, thanks!
Thanks Tom. Tips very important. O don't bind
I don't know bind other transmiter
Glad to help
I’m looking at the ready to fly version because it’s on sale for 249.99. The BNF is 269.99. I have a NX6 do I need a bind plug to use my NX6 with the RTF version?? Or would you recommend a different model. Thank You
The RTF is the the same airplane without the transmitter. A bind plug will work on either for binding to your transmitter.
On your elevator to aileron all you have to do is program in a mix aileron to. elevator so when you bank with the ailerons it will automatically apply elevator.
That is correct IF you have a programmable transmitter. The DX S that comes with the RTF version is not programmable, and that is the transmitter version intended for this video.
I've bought the carbon cup S2RTF and I cannot get the mode switch to to go into the beginner mode. If I push the panic button the green light comes on otherwise otherwise it's either red or blue. Any suggestions on what I'm doing wrong um?
Hi, I am not sure. On that model's transmitter the button is only for binding. It has nothing to do with flight modes. The 3 position toggle on the top left side of the transmitter sets beginner/intermediate/advanced flight modes. If you bind the model correctly it should work. Try re-binding and follow the manual precisely. If that fails pull up the Horizon site and use their tech support/chat line to try and sort it out.
Does this aircraft still use the stock ESC, or did you upgrade it with a better one? Thanks.
It had the stock esc when I outgrew and sold it.
@@GoofballFlyer Thank you for the prompt reply.
I have been manually adjusting flaps using tooth pics to position them since I only have the dxs controller and was told flaps won't work with it so was wondering how you got the flaps to work with the dxs controller
You don’t. I think it’s explained in the manual that you need a full feature transmitter. I bought the NX8 but there are less expensive options. You will need that anyway to make any progress in the hobby. The spectrum transmitter line has excellent resale value if you buy and change your mind.
More...
Actually you can get the flaps to work with the DX S. BUT, if you do that the aircraft is almost uncontrollable in pitch. When the flaps come down on a high wing aircraft there is a strong pitch-up tendency that can cause a stall. The more power the stronger the pitch-up force too. It's created by downwash off the flaps hitting the top of the horizontal stabilizer. On a programmable transmitter you can create a flaps/elevator mix that offsets the pitch-up. I DO NOT recommend using flaps without that mix programmed.
How did you set up flaps with SAFE on your NX transmitter?
The manual has those instructions.
More, the manual has basic instructions including the flaps/elevator mix required on page 20. I found the recommended mix was OK.
I new to this and you were dead on on the aileron hinges.
To be fair this model's hinges are not typical of those on other E-Flite products. In my experience these are particularly flimsly.
What is the stand your using for them?
Robards
Have you flown that extra? If so, what do you think?
I lost my nerve and sold it un-flown. I have stayed in close touch with the buyer and it's his favorite plane. That's saying something too, he owns about 20.
@@GoofballFlyer Ah ok, too bad. It’s on my short list of planes to try and I enjoyed this video so was curious on your opinion. Take care.
This really prepared me for my first flight of this plane. I have to say though, you are a little too harsh on the plane I think. I thought it was very very easy to learn on.
It was a good flyer but suffers in comparison to the Turbo Timber Evo.
The wing struts a a weak point. If you perform any kind of aerobic maneuvers, keep an eye on the wing struts getting into the ailerons servos.
I tried flying it without the struts. Positive G maneuvers can really bend the wings. I was not comfortable with that and put the struts back on the airplane.
Thank you yes they are real airoplanes, I must tell hundreds of people that they are real, If it was not real you would not be able to see it or touch it.
They are very real and not easy to fly. Even a $5 balsa glider or a folded paper version is a real airplane. I use both in classroom demonstrations.
@@GoofballFlyer Yes Correct.
My name is Francis
Friends don't let friends fly slimers. Lol
I bought a used carbon cub s2. Got to watch it fly. Got it home and can’t seem to get it airborne. It lifts 8 inches off the ground and I back out. Breaking the prop. Am I not going the extra step and add more throttle? Is the elevators off? Can you help? Just subscribed because I understand you.
Sorry to be so late on the reply. It needs full throttle and does not like grass over 1" high.
