I'm new to the helicopter world. A couple of friends fly them so I thought I would give it a try. I bought the Raptor G2. I didn't want to spend alot of $$$ just in case I didn't enjoy it. After a couple of crashes and minor repairs, I had the heli stable and hovering. Now, everytime I leave the ground, the heli turns left. I max the controller all the way to the right and it still turns left. I adjusted the tail servo and the heli still turns left. My friends who fly didn't have an answer for me so I hope someone on this board can point me in the right direction. Any thoughts?

Check the tail rotor direction, is it rotating in the right direction?

Sorry it took so long to respond, I was out for the weekend. Yes, the tail rotor is rotating in the right direction. It's a belt driven tail motor.

Ckeck your belt. It is possible after a couple of crashes to strip some of the teeth on your belt. That will cause your tail rotor to tuen too slwly when it hits the bad spots. (Just a thought)

I haven't checked the belt teeth. I did check the tention thinking maybe it was causing the rotor to turn slow but didn't think to look at the teeth. I'll take a look at that and post what I find.

There is a steel pin in the plastic pulley of the tail. I had one shear off and at another time it just started to come out. Check that pin making sure it is properly inserted locking pulley to shaft.

Missileman is right; check the belt and the direction of it and the tail-rotor rotation. Second is that your gyro may be out of gain adjustment or bad, to check that disable the main motor by removing its wires from the speed controller (remember the order of the wires) turn the tx on and connect the battery, set the throttle at half or quarter settings, then lift the heli and sway the tail to left and right, in the mean time look at the pitch on the tail rotor and see if it is responding to the opposite direction, if not check the gyro and set it up per the manual instruction.

Good Luck, Raz

I checked the belt and all the teeth were good. The plastic pully on the tail is locked into place. Thanks for all the info. I'll check the gyro tomorrow.

One more thing to check (because it just happened to my T-Rex) check your tail servo. I lost a couple of teeth on one of the gears and the servo started to stick at the bad spot.

I checked the gyro as described. When I move the throtle up without moving the heli, the tail rotor sliding sleeve moves all the way left. Is this normal? If I keep the throtle all the way down and then move the heli left and right, the tail rotor does pitch the proper way.

I'm not sure but is it possible to have two channels on the same stick? That may be the case if it is. Wait! Cp helis do! The collective and throttle are! That may be the problem then.

That should be normal due to the "revmix" on the tx throutle, meaning the higher the main rotor speed is the tail rotor has to work harder to compencate the torque. What part of the heli was damaged last that replacing it caused the problem.

The last thing I replaced was the main shaft and swashplate. After I replaced them, the helicopter flew fine. It was actually the most stable it's been. The next night, it stared having problems. That's the most frustrating part. One night it's flying great and the next night all the problems start. The only difference was the day.

Hey, I have a raptorr and mine used to due this. When no throttle is added are your tail rotor blades perfectly straight and no pitch on them if not, move the servo around and stuff. If they are perfectly straight then move the servo to where that there is a little pitch on the blades to counter react the left spin. Also have you taken the servo horn off of the servo because the tail slide shouldnt move all the way over so take the sero horn off again and put all the controls at center and put the servo horn back on so the blades are perfect. hope this helps
