- A couple of little modifications which make the v911s a bit easier to fly. Less twitchy.
Details and buy here www.banggood.c...
Please be careful if attempting them as there is a chance you could damage the heli if you aren't good at fiddly little engineering work! So work carefully please if you want to try them at your own risk.

Awesome video!! So useful tips!
Glad you think so!
"You need a steady hand" hahahaha - great vid thanks for the info. Glue works yes but most screwdrivers are magnetised but when they aren't I just stick a small neo magnet to the shaft and it magnetizes the whole screwdriver - essential when working with small systems like this.
For sure, I do have some magnetic ones. But you sure do need a steady hand, and mine aren't as good as they used to be!
@@bobflyman I 100% I am an aeronautical illustrator so I understand steady hands but I laughed because your hand was shaking so much it almost defined the video and when you said "you need a steady hand" I had to comment - all in good fun. I enjoyed your vid thanks and happy/steady landings
Just received this model from Aliexpress. Not flown yet but have done the mods you have shown here. Did them in reverse order - swash plate first, then popped off the links to the servo and changed the arm hole mount then popped the ball joint back in. I do not have much luck with small screws so did that to avoid loosing the screws. Anyway, thank you for your tips and keep up the great work. Happy New Year from Invercargill, New Zealand.
Thanks Sandy, it certainly made it a bit more controllable for me, though maybe I'm a rubbish chopper flyer! Hope it works for you mate.
Nicely done! I've seen quite a few V911s videos posted by folks who have not taken the time to learn how to utilize all of the transmitter functions to properly trim and save settings. You perfectly explained that. And the other essential adjustments you made really improved the V911s behavior. My "hanger" is out of space and I'm not actually looking to expand the fleet, but for a $40.00 ship, it's really impressive and hard not to purchase one "just because"... I hope anyone who purchases a V911s finds your fine video. Happy flying!
Thanks mate. It's good for the money but I find it hard to be precise when flying it. Some people I think have managed to fly it with a better tx with good results.
@@bobflyman, do you think it could be binded to a Spektrum DX9 radio? Thanks, Bobby
Sorry only just seen this one. Not sure, I'd check the RC group forums. I doubt it though.
@@bobflyman V911s protocol has been hacked a couple of months ago. With the latest firmware updates you will be able to fly this with a multi-protocol module equipped Tx. That protocol is also used on the XK A100 series 3-channel planes. (A100 jet, A110 predator, A120 A380 airbus, A130 cargo, etc.)
@@theoztreecrasher2647 thanks for that info. I knew ages back that the idea was being worked on, but didn't know they had succeeded. Nice one. I wish I owned a DX9 or similar!
These are great tips! Thank you. It was definitely easy to loose control of it at first. I tried it in my kitchen first and that was a mistake. It swung into a cupboard and busted the tail. Fortunately it was right at the base, so I pulled the broken piece out, and put the rest of it back in. So the tail is about a half inch shorter now, but it still works! But I bought a few spare tails online just in case.
I bought this for my 7 year old son, but I have a feeling he's going to put this in the top of a tree the first time he uses it.
Thanks mate, and yes, it is a handful even just to get a stable hover. It was my first 'proper' heli' , others were contra rotating types. Easy! The mods help a bit but it's not easy to fly indoors. I find it OK outdoors if there is not a lot of wind. Might be good to start your 7 year old with a twin rotor one? I had a Syma that was great to fly and survived until the board went down. Could try that? I've never done a video on them. There's a test here th-cam.com/video/TUDWHOega68/w-d-xo.html www.amazon.co.uk/Syma-S107G-Version-Indoor-Helicopter/dp/B00BFSF66O/ref=asc_df_B00BFSF66O/?tag=googshopuk-21&linkCode=df0&hvadid=310066351121&hvpos=&hvnetw=g&hvrand=2624467667992564727&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1007173&hvtargid=pla-589465996796&psc=1
@@bobflyman Yeah, he did have a twin rotor on before, but broke the stabilizer bar. This one doesn't have replacement parts available and I'm not sure how to fix it. I'd hate to just throw it away when everything else works.

@@bobflyman the best coax for indoor use is by far the blade mcx2. You can still pick them up in 2020 and parts still available.
I am using almost the same settings that I created for my Blade 130X with RadioMaster TX16S and this thing flys super smooth and precise with FPV. Amazing with fpv, better than drones.
Brilliant mate!
Thanks for this video it's helped me out quite a bit 👍🏻👍🏻
That's great! Enjoy.
I've been flying three of these 'out of the box' on the stock transmitters, both indoor and out. I personally enjoy the 'twitchy' flight characteristics. I've found it ups the skill set.
Agreed, it does!
thanks that first tip made it much more flyable indoors :D what a great little chopper
Great. I flew mine outside yesterday. First time in quite a while. I'd forgotten what fun it was!
Good video mate,, a tip for others, you don't need to undo the screws on the servo arms, unpop the ball joint on the servo lever attached to the swash plate, its A LOT easier..
I did the ball joint thing too. But moving in a hole on the servo cut movement even more.
@@bobflyman yeah I mean still move the linkage to a different whole in the servo arm/horn but instead of having to unscrew the servo arm/horn all you have to do is pop the linkage off the swash plates then change holes rather then having to undo the screw and struggle with realignment.. 👍
@@MarcRCAddict I think I tried that. Maybe I should have tried harder!
@@bobflyman Yes, I was wondering that as well. Lol! Way easier with that motor in the way. I would only be removing that servo arm if it was placed wrong from the factory, causing the swash plate to not sit flat.
Thank you for the info on 'hover debugging.'
I started out with a helicopter that required about 16 ticks right and six or so back on the tx in order to attain an unstable hover. Even with the trim, it was _very_ twitchy and the response to inputs was quite unpredictable. 10 full turns of the aileron push rod screw, had no noticeable effect(thanks to the gyro undoing my 'fix' in order to 'level' the fc no doubt.)
I took apart the rotor head to see if there was anything strange, and noticed that it took some force to insert the swash's guide pin into the anti-rotation slot, which didn't seem right. After only a few flights, it was already generating plastic dust and starting to wear down the pin. I measured the pin at the point of contact as being almost 0.1mm larger than the slot.
With an emery board, I sanded the slot to fit the pin, finding that the heli's response seemed a bit less twitchy afterward, but still not even close to a stable hover.
Like you, I noticed that installing the battery caused the fc board to tilt diagonally. Two loose o-rings got the foam under control. Still the heli wanted the same amount of right and back trim and still no stable hover.
I just followed your 'hover debugging' procedure, and now she sits stock still(wrt roll anyway) with no tx trim, and is much less unpredictable. She still slides forward and back, and likes to thump her tail a bit, but I feel comfortable enough to do circuits inside now, which wasn't even close to being true previously. My swash now looks level at rest, and the servo horns are neutral with no input, as they should be.
Thanks again.
Brilliant mate! Part of the fun of these cheap little flying machines is getting them to work properly. Mine was at max right trim and still going the left as well. I'll take another look at my swash guide pin. I think it's OK. There's some good stuff on RC Groups about this little chopper if you haven't already seen it?
Thanks for the hover debugging info. The included information was not clear. I’ve got mine hovering nicely now thanks to you !
It's just a j-hook so you can simply pop off the ball joint and hook it to the inner or outer hole as preferred.
Try it? You can't get it out of the servo arm unless you remove it. Trust me!
You don't have to unscrew these screws. Just take it gently off the link on top. It is easy to adjust this way.
If you want to change to position of the link on the servo arm you DO need to undo the screws.
@@bobflyman no you don't, pop off the link and then swivel the control arm out of the hole, then place it into the other hole and swivel it back upright.
@@bobflyman u r wrong sorry
@Sigman kiero etusormi I If you say so. Why not make a video and you show me how you can unhook the control wire from the servo without removing the arm. It can't be done. But I'm sure you know best. 😉
Just gotten mine, these mods work great, thank you for the video
You're welcome mate!
Bought one in 2020.....great little flyers
Just the job for flying inside while the weather is bad and we get locked down!
You can do the same thing in an OpenTX Multi protocol radio with RATES and EXPO.
Yes, if you have a tx that will communicate with the heli. Mine doesn't! And a lot of other people can't either.
Thanks mate. It certainly helped with mine!
Hi Bob need some advice my v911s main motor gets too hot n also what glue should i use to replaced main motor appreciate thks..
Sorry no idea why motor would be getting hot? 😯 Glue ? I use a hot glue gun, but something like Uhu Por might be better. Slower and not hot!
@@bobflyman OK thank you 👍😊
Your main shaft is Loose! I noticed it when you were moving the servo it was actuating up and down push the main gear back up tight or check the retainer collar under the swash plate their should be no play on main shaft ! That can cause all kinds of issues in control !
Thanks, I'll take a look at that.
I miss my helicopter. And I'm trying it again. Do what you say to do. I've got a bunch of money in this helicopter. And you're explaining how to do it it's going to make it more fun to fly
They are great fun to fly! Enjoy mate.😎
Hey Bob - did you ever get your hands on the Eachine E119 which I suggested? 🚁🚁🚁
Great heli and appears to use exactly the same layout, albeit slightly larger.
VERY easy to unhook the servo arms without touching the screws but by moving the linkages in closer, they also raise the swashplate ever so slightly.
Again, easily compensated with a few turns of the threaded connector before snapping it back onto the ball joint! 😉
Hi ya, no never got hold of one. Too many toys already as well!
bobflyman 😆 hahaha! I REALLY recommend the Eachine! ✅
In these times, it's worth getting a new toy my friend - Banggood are doing them for just $39 👍🏻
PS You can choose between 2, 3 or even FOUR batteries.
I thought 3 was plenty because each battery gives you 15 minutes flight time! 😀
@@nutleighgrove3658 I checked it out, it does look good, but £47 a bit different to the £30 the 911s cost. But no doubt a better flyer! I've got 3 RC planes to maiden at the moment maybe I'll get one of those after that! cheers.
You don't have to remove any screws or remove servo arm to swap holes. The control arms pop out of the socket above where they connect to the swash plate.
I do the swash plate a 6:03 . BUT if you do the servo arms too, it is even better.
what is the effect of moving the control rods to the inner hole, smother flight?
Yes , it helps a bit.
It's all in the angle of the dangle mate Good Show Yank Here's looking Up your adress❗💓 🇺🇸
Thanks. Yup, everything comes down to the angle of the dangle!
Thanks for tips:),
only the most nervous command is the rudder (left stick). How could I make that smoother?
Good question, I wish I knew how! I've just been flying mine indoors and I still find it a handful. Not busted it so far though!
I use a small magnetic screwdriver instead of prit stick but I’m sure I could use it for other things like lube! That small helicopter looks like a turd compared to my XK 130 because when you move the sticks the whole upper parts of the head move from what looks like the plastic balls as well as why it moves in flight like it does. I’ve been flying hard 3D for 18 years. My main Helicopters are the ALIGN HELICOPTERS although I’ve owed every major brand.
But you need more angle of attack in servo to more sufficient fight on strong winds
True, but I don't fly in strong winds ;)
@@bobflyman 👍
Pop it off the round ball link on top.
Nice video and good camera angles, thanks. I think I'll do your mod #1, but not even try mod #2. On Mod #1, how critical to the 911's performance was rotating the linkage arm 180 degrees and going in from the front?
Thanks mate. I'm not sure how critical mod 2 was as I only tried to fly it briefly before the mods. I still find it a bit of a handful to fly, and other comments I've seen on forums seem to say the same. I think someone was trying to reprogram the tx to improve things, but that's way beyond my expertise!
Rather than take the servo horn off, why didn’t you just pop the ball link off, it’s a lot easier.
I did both! The ball link reduces some travel, the servo arm mod removes even more travel!
No disrespect at all but this all you are doing is decreasing the movement of the swash plate, making the heli alot easier to control but you are losing all your range of movement, okay for starting out but you soon be craving more. I found it much better in the advanced swash setting and controller setting out of the box, the yaw i found particularly slow on these heli's but this obviously has nothing to do with the swash.
Your comments may well be true for people used to helis. I found it almost impossible indoors until I toned it down a bit?
@@bobflyman You need a good open area to fly these. Believe it or not when they are up in the air they perform unbelievable, I'm fairly new to flying heli's, if you want to fly indoors you have no chance with these. If you want to fly indoors you need something completely different.
Nice Video due i am the 4004 sub ;.)
Thanks. I seem to have lost a couple, back to 4,000. Might be cos very few action cameras too test now. I've done them all. RC plane will be next in a couple of weeks when it turns up!
Could it still make the helicopter fly normal if you just adjust the servo and not the swashplate anymore?
That's what I did by moving the point where the connecting wire was attached.
@@bobflyman ok I haven't flown mine yet because I accidentally bought bind n fly ver. of v911s still waiting to buy the remote can't wait to fly it
@@rexx8887 I still find it quite lively even with my mods. Have fun mate.
@@bobflyman thanks for the tips bob really appreciate
@@rexx8887 No worries mate!
I did it now it won't fly just leans over as I start it how do I fix it now
Sounds like either trim is way off, OR the circuit board is canted on it's mount.
@@bobflyman i fixed it all good
@@MrCaptiv8 great!
Or just switch from mode 2 to mode 1 and it decreases all the servo throw.
Didn't know that, but I can't fly mode 1! 😕
The biggest problem I find is the throttle. It drifts up and down a lot. Still a great little learner heli and even better that you can fly indoors. I can’t get it to work outdoors as it can’t cope with any gusts.
???? IS BRUSHLESS OR BRUSHED engine ?????
it tells you in the product description on my link! You won't get brushless at this price! It uses the 8520 coreless main motor
Isn't it possible to remove the metal actuator without needing to unscrew the white plastic piece (and thus avoid the tricky glue procedure?)
I don't think so, but you might find a way to do it? Experiment?
@@bobflyman I just ordered the heli and I will test this as soon as it arrives. I'll let ya know how it goes ;)
Great. It is quite lively to fly, well I found it so anyway! But I'm not really experience in small helis.
Hi Bobflyman! Excellent hacking - thanks! 😊
Have you come across the Eachine E119 ? Apart from great batteries, it reminds me of my 911s.
My son found the 911s too aggressive and twitchy for a beginner , I wonder if the new Eachine E119 would be more docile in small areas or just as lively as the 911s ?? (It does have 2 speed rates but would love to hear your views)
Thanks my friend, Martin. 🚁🚁
Thanks mate. I'm not familiar with the Eachine E119. Some people more clever than me have I think hacked the receiver on this and made more improvements, but at least these small changes make it a bit more flyable. I still find it a challenge!
bobflyman Type it in the search box, really impressive batteries are included, might order one. Let me know what you think.The V911s is great but still a handful 😅
@@nutleighgrove3658 thanks, will do!
I have two of these with the same problem. Sometimes they will just die in the air for no apparent reason. Always within 40 meters. I don’t know if it is lost connection or power. Any idea of what it is ?
I would guess out of range?
@Pretty fly for a WiFi probably loss of signal?
@Pretty fly for a WiFi Mmmm. 10 feet. That's not good!
@Pretty fly for a WiFi You'd be ok I'm sure, out of thousands sold that's only a couple of people who have said they had a problem. But it is a bit of handful to fly. Better if you make the mods to it. Good price too.
Big battery its trouble.... A engine is very hot....
clipping the battery box may weaken the structure
of the frame
yes, maybe a little bit. It's only a thin bit of plastic. I have flown the heli a lot and it's still in good shape!
