WL Toys v911S helicopter Tweaks+Tuning. Make it easier to fly! 

Awesome video!! So useful tips!

"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.

Thanks for this video it's helped me out quite a bit 👍🏻👍🏻

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.

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.

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.

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!

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.

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..

thanks that first tip made it much more flyable indoors :D what a great little chopper

You don't have to unscrew these screws. Just take it gently off the link on top. It is easy to adjust this way.

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.

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.

Just gotten mine, these mods work great, thank you for the video

Thanks mate. It certainly helped with mine!

Bought one in 2020.....great little flyers

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! 😉

You can do the same thing in an OpenTX Multi protocol radio with RATES and EXPO.

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..

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.

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 for tips:), only the most nervous command is the rudder (left stick). How could I make that smoother?

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.

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

what is the effect of moving the control rods to the inner hole, smother flight?

But you need more angle of attack in servo to more sufficient fight on strong winds

Pop it off the round ball link on top.

It's all in the angle of the dangle mate Good Show Yank Here's looking Up your adress❗💓 🇺🇸

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?

Could it still make the helicopter fly normal if you just adjust the servo and not the swashplate anymore?

Rather than take the servo horn off, why didn’t you just pop the ball link off, it’s a lot easier.

I did it now it won't fly just leans over as I start it how do I fix it now

Nice Video due i am the 4004 sub ;.)

???? IS BRUSHLESS OR BRUSHED engine ?????

Or just switch from mode 2 to mode 1 and it decreases all the servo throw.

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.

Isn't it possible to remove the metal actuator without needing to unscrew the white plastic piece (and thus avoid the tricky glue procedure?)

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. 🚁🚁

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 ?

Big battery its trouble.... A engine is very hot....

clipping the battery box may weaken the structure of the frame

Hello,I just bought this helicopter, please can I ask you for information.? Do you have an email or instagram?
