RE: Please, give me an answer!
heres a few Ideas for better tail tracking. there are a few possible causes.
First simply add a small amount of gain on your gyros adjustment pot, if the tail wiggles you have gone too far and should turn it back toward the negative slightly until you have no tail wag at a hover.
If your bird is a single rotor, you can try moving the tail servo slightly along the tailboom, making note of which way the tail blades move. Set your rudder trim to zero and turn on your radio and heli. At this point the tail blades trailing edge should be a little to the right of center with the heli.
You can also move the ball link at the servo one hole away from center if the tail cannot be made to wag at the maximum gyro gain.
If your heli is belt driven, check the belt tension, the procedure is here in the forum somewhere...
Add a little head speed to give your tail blades more holding power. You can do this by a small increase in the throttle curve, or a slight reduction in the pitch curve.
And just for the sake of being thorough, you can lube the tailbelt. Use a non petroleum based lubricant as petroleum products will break down the belt. Somewhere in here I read about using food grade spray lubricant, whatever that is.
Hope this helps[8D]
