After adjusting the dip switches (channel reversing on the APM board) I got it to respond in Stabilize mode. Now when holding it if you pitch it any direction the control surfaces move to return in to level flight. It performed well in its test flight but autopilot still isn't working along with Return To Launch mode. I have been doing lots of research on the diydrones.com forum but have not found anything. When switched into either of these modes the plane banks hard right, goes full throttle and stays in a fast, tight circle.
