I ordered a new tail servo and it came in today. Installed new servo and tried a test flight. No change still spins out of control. Servo seems to move slowly, but there is no binding anywhere in the tail. It all moves very freely. Tried resetting gyro and re-centering but it made no difference. Checked all transmitter settings and nothing has changed. It is as if the gyro has quit working.
Anyone experienced a similar problem or have any ideas. There may be something somewhere in this forum but I haven't had time to read through 400 posts...
Any chance one of the tail drive gears are stripped out and the tail rotor won't get up to speed?
