Did you have a tough time centering the rear tail shaft in RATE mode. Please tell me your process because we could not get it centered. Thanks and great vids.

@sundown798 there are a few things you must check first, Do not use any rudder trim. You must be sure the servo is centred, use the best servo horn that sits as centered as possible. Make sure you have full movement left/right without the tail rotor control arm touching either the metal plate/rotor hub. Once sure the above is all correct, Test fly carefully, take note which way the tail drifts, land, loosen the servo brackets and slide the servo either way 1mm at a time.

Thanks for watching.

@MrSpeedy01 Yeah the problem was my buddy didn't push the boom in all the way in the mount. Thanks.

Move the TX stick to the right look at the heli tail on the right servo should move down the left servo up the back servo shouldn't move. Move the TX stick to the left, left servo should move down, right servo up and back servo shouldn’t move. Then move your stick forward left and right servo should move down back servo should move up. Move stick down the back servo will move down, left / right servos should move up, if the above isn’t happening you need reverse servos, do this before centering.

how will i know if the servos are reversed unless I run it?
