YUP ranged checked. Using DX-7 Spectrum all around. Hi torque servos on airlerons and elevators. Completely dissasembled the plane yesterday and laid out all the electronics as installed. Went over everything over and over and they all moved in the right direction. I replayed what I did from throttling up (throttle servo totalled) to picturing it going down the runway, lifting and rolling, and me inputing commands. After retracts went up, its a total mind boggle. All control surfaces moved correctly to compensate for roll but plane kept rolling. My conclusion was that it was a Torque Induced Roll. TOO much Power. Saito 220 swinging a 16 x 8 3-blade. []
