Hi all,

I've been setting up a shuttle I picked up used for the past couple days. I am at the point where I am running it up on the ground to make sure it is responding how it should be. My problem is that when I get to near half throttle, the heli starts spinning very quickly clockwise. I can correct with rudder somewhat but not really. I have a thunder tiger piezo gyro installed, with the aux (gain?) plugged into channel 5, and the ATV's set at -50, +50. Nither position of the landing gear switch (ch5) makes much of a difference.

I have no instructions for the gyro, and haven't been able to find any on the web. Can anyone help me out? Has anyone run into something like this?

Thanks!
