Just took out a scratch build for maiden. I threw it and it went vertical immediately, fought with it for about a minute, but couldn't get into level flight. Had to ditch it before it got into bad location. I checked all control surfaces before and after (after getting it out of a tree) and they all looked good. Only damage it took was knocking the motor mount off and busted prop. Any suggestions as to why the immediate climb and wanting to stay vertical?
