I took my Voyager E out for it's first flight this morning and was disappointed to find that the tail started wobbling back and forth violently at about half throttle. Of course, I didn't want to attempt a hover with this problem. I'm using a Futaba GY401 gyro that seemed to be operating as I expected. The tail rotor is connnected by a tight belt to the gears that run the main rotor.

I live on an Island, so I don't have any local people to help me out. Any ideas on what could be causing this problem and how to correct it?

Be sure to position the gyro as close to the main shaft as possible. I had this problem with a sceadu untill I put the gyro right in front of the main shaft.

Adjust your gain. Sounds like to me you have too much gain. If you have too much gain, it will "wag" your helis tail. If you don't have enough gain, it will drift (meaning it will the tail will keep moving in one direction). It wobbles at half throttle because thats when the gyro thinks you have way too much headspeed. The higher the headspeed, the less gain your going to have to adjust your gyro.
