OK, had more test flights today. I turned the GPS slightly to the left and it worked, flew solid in Atti and GPS modes. Thought problem was fixed, then switched out batteries, same size and mah. Took off and it drifted the other direction (left)
Landed, powered down and turned the GPS back to the right. Powered back up and it flew perfect again. I would have done it again but only had 2 batteries. Seems like i have to adjust the GPS every flight, that doesn't seem right.
