first off do yourself a favor and toss the stock electronics in the trash seriously everything except the motor. yes even the stock lipo ITS ALL JUNK!! but how is your mechanical setup firstoff? you should be able to hover with little to no tail input in rate mode. if you cant then you need to fix the mechanical 0 first! also the gyro is very very lousy how are the vibrations ?? can you upload a picture of the tail blades. its a new one on me are you sure the tail is moving the correct way ie the way you twist the belt then turn main rotor clockwise looking down if the tail turns ccw the the fat edge needs to lead. i have chewed up tail blades but its usually on the tips and on the leading edge because there isnt enough material. upload a pic !
