V911 Issues
I am a newbie to these RC helis. I have a question about my new WL V911. When flying, it tends to circle to the right and doesn't just hover. I can hold it at constant throttle and it will pretty much stay in the same 5-6 foot diameter circle. Also, when you take off from a table or the ground, it pulls hard to the left. The ones I see on internet videos do not exhibit this behavior. I've tried "trimming" it with the controller and that seems to have no effect on the helicopter. Is there a remedy for this or is mine defective?

I have tried adjusting this thing and nothing seems to work. Do I need to send it back?

About your V911 issues. I'm new to these RC chopper fying also but I may be able to help some. I got 2 of the V911's not long ago and also found the hard left on take off. so I actually kept mine on the floor just shooting around until I got it under control. Then I found this place and started reading everything I could find on Setting up the 100 size heli's. I'm still searching and reading! Great Place Here! Anyway, What I had to do was to center the Bell Cranks on the 2 survos and then go from there and level the swash plate with the push rod's adjustment. Recenter your TX before binding again to your chopper. the Bell cranks should be at a 90 deg angle from the survo, like taking a T and laying it on it's side. You will have to remove the tiny screws holding the bell cranks on and remove the BC from the splined survo pinion. I suggest that you remove both arms and then put the battery back into the chopper and then rebind to it with ALL trim setting at center neutral positions. After binding move your right joystick around in a complete circle to get the survo's loose and working. after doing that, shut down everything, and remove the battery from the chopper. Now put the Bell cranks back onto the survo's as described. the lazy T. Remember the survo pinion and the Bell crank are splined so you will just have to get as close as possibly can. Be careful when putting the screws back into the bell cranks, don't tighten so tight that you turn the arm. You don't want to do that. Now with the bell cranks replaced. Check the Swash plate and see how level it is. They do have a tool to set the swash plate Exactly level with; but I don't have one myself so I eye it, "works for me, gets close enough to enable smooth hovering." If the swash plate is not level you then need to either shorten or lengthen the push rods that connect the survo to the swash plate's control arms. Once you've done this, put her back together and give her a test flight. Only use the Trim controls on the TX to do very minor adjustments. Give that a try. I had to do it on mine... worked fer me! Sorry for the long winded explanation! Hope that made sense and helps you out a bit. Good luck and happy flying! Last edited by Tecpro; 08-12-2012 at 01:10 PM.. |

It's funny, I messed around with the heli later in the day after I made this post. I noticed the bell cranks (I learned something new) were not both at 90 degrees. Looking from the rear, the one on the right was down about 30 degrees. I took it off and repositioned it. I also shortened the push rod. The swash plate may need to be a little more level. The bird still takes off to the left, but not as hard. It still wants to fly in circles (to the right), but not as bad. I am still not sure if the controller is working correctly because the trim changes seem to do nothing. The button at the top near the antenna doesn't do a thing. I've gotten pretty decent flying this thing. My children (2 & 4 years old) love watching me fly it too. We've had a couple really nice mornings in a row with little to no breeze. Flying it on mornings like that has been very enjoyable. I'm already wanting to step up to a 6 channel unit!! |

After you did the setup to level the swash plate and adjusting the arms, here is a hint to not doing a hard left on take off. Do your preflight checks and then warm up the chopper on low rotor speed for a few seconds. Now when you want to lift off, slowly add more power to the point that it just about lifts off. Add just a little right forward stick, just a little now, and add power and lifter up like you were only go about 2 feet up. get used to putting that little bit of right stick on take off. I found that it only does a Hard left is when the power at lift is launched to high power all at once. Try the slow lift off with a little right tilt. see if that works any better! Just an FYI; you can fly the V911 in light wind. you just have to compensate with the control stick. Move the control stick gently or ya will jet around. Also, DO NOT fully discharge the batteries nor over charge them. this will shorten the life of them greatly. I Time my flight to approx 7 minutes or until the chopper wants to start loosing power and dropping down by it's self. then I change out the battery and recharge. I MUST say as a Noobie myself, I learnt all this by being here in the threads and reading as much as I can, and I'm still reading and learning. These people are great!

Thanks again for the tips. I'm getting better flying this thing every day. It still wants to drift to the left/forward. When you spin it clock wise, it wants to circle instead. I think the tail rotor might be spinning too fast. Either way, I'm really enjoying this and now would like to move up to a really nice outdoor chopper. I wish I had someone local to hook up with and talk about this stuff.

Any heli with a tail rotor will tend to go to the left when taking off. It's from the tail rotor thrust. If you try to trim it out you'll end up with a heli that goes right after taking off. The solution is to give the heli a little right cyclic as soon as it lifts off. You'll eventually do it without a thought. When you hover there will be a little right cyclic in play to offset the tail rotor thrust.

The more throttle the faster both main motor and tail motor will spin at the same time. So keep in mind that if you give your bird a sudden burst of throttle the tail will probably move also.

I finally have gotten to where I can control the thing pretty good. I tried flipping the flybar over and made the swashplate level. I still have that left/forward drift. I crashed it into the wall tonight and lost one of the flybar weights. That gave me an excuse to order a few parts, another V911 (Yellow one!), and a 5 pack of 150mAh batteries. So, I guess I'm down for 7-15 days. Back to the coax. chopper for the time being.

Here is a place local that ships from the USA. and they are in Houston, TX
http://www.ujtoys.com/WLToys-V911-He...arts-s/344.htm and that is direct to the V911 parts page. I use them. And on the left/forward drift... knowing that it will do that everytime, use your stick control to put a little right/rear tilt to it during take off... after a while you'll do it automatic. Sorry but that's just one of the little give and takes of the hobby.

I am brand new to RC heli's. I have a Syma S107G which is a great trainer. I also bought a V911 at the same time and haven't had any luck getting it flying right. I have the same problem as it tends to dash to the left pretty hard on take-off. Does anyone have a diagram that labels all the parts so I know what to adjust? I am a complete newbie to this stuff but do enjoy it.

Check the manual that came with the V911. It has an exploded view of the chopper and they are numbered with a list matching each part. Read my earlier post for help on what you need to do! If you need help let me know. I can send you an electronic copy of the manual and I'll list the names on the exploded view.

V911 tail motor seat replacement
I crashed this heli on the first day i had it and broke the white end off of the tail motor (opposite of the blade) the motor seat is still in tact but there's a lip on the end of it that prevents me from trying to reassemble the motor. Is there anyway to remove the motor without destroying the seat?

If the tail motor is shot and needs replacing you can heat some water up to just below Boil. stick the motor into the water for about 1 minnute. Remove the blade, on the back side of the motor where the white cap is on the motor you will see a small black Lip that holds the motor in... take a very small flat tip or use your finger nail to pry that lip back ONLY far enough to push the motor from the blade end out the back. Change the motor out and reverse the process. Minus getting the motor wet. I'm sure you know that part.
If I can help you, just pm me. Don't reassemble the motor... won't be any good.... cheaper and easier to buy one. See my earlier post for a local Houston Texas place to buy parts cheap!

I oredered a new motor but haven't really had time to try your process. I'll probably be able to get to it tomorrow and let you know how it goes, Thanks!

Reinstalling tail motor
1) Heat the tail again, in water that is just below boiling.
2) remove from water and dry quickly 3) install motor 4) install blade, No need to heat 5) cut wires and Solder wires together; use heat shrink after wires are soldered. Place heat shrink down the line on the wires before soldering then solder, cool solder, move heat shrink over the joint then apply just enough heat from match or lighter to shrink. Heat shrink, solder, and iron can be gotten at Radio Shack fairly cheap! Make sure that both solder joints are separated and covered with either Heat shrink or Electrician's Tape. Make sure that you do put the tail blade back on facing the correct way! IE: the longest part of the main shaft of the blade base goes toward the motor. Enjoy.

Hard Left on lift off? See This!
Look at my attachment for a complete 'how to' on correcting this Issue with only
a small piece of plastic and a drop of super glue. Some might try Thick CA in the slot, keeping the arm out of the CA until it drys. But this method DID work for me! You can right click on the pic and do a save image as so you can view it in your favorite viewer and inlarge it for clearity. This is a Freeware image I created or modified from the V911 manual and added My explanation and drawing to it. Or you can PM me and I can email you the large version or link to it in my Photo album. Remember to spool up slowly to just light on the skids then give it a 10 to 15 percent more throttle for a smoother lift off.... Following my diagram and that last sentence should get you in the air with fewer problems and smoother flight. Thank you

I have 4 v911's my first one did the same thing and I lived with it till I saw a setup video on Youtube that showed my silly old ass, DURF, adjust the left Tie Rod end up a couple turns and problem solved. I also find that my Flysky CT6B radio does a MUCH better job of controlling it than the one that comes with it.

Cool. I tried adjusting mine, like that. after I did then it drifted to the right more so I reset it back to level. I'll give it another go on my other bird and if it finally works then I'll remove the piece I attached to this one. I'm flying the V911 in the house when it's too windy out to fly the Huey, which will probably get to be quit a bit this winter, every input helps someone.
Thanks Kwekwe

No problemo. My biggest problem now is figuring the proper settings to use for my Flysky CT6B radio to control this. I'm using the Acro type since no pitch etc this way and it works pretty darn good but I'm sure I'm missing something somewhere as I understand it SUPPOSED to be programmed using the Heli90 settings.
And Bone Head me dropped original radio and busted the Plastic Antenna protector. |
