Well, I raised the engine about three sixteenth's inch and put two washers behind each upper engine mount and the problem has been reduced by one-half. I put one more washer in and will fly it soon. I definintely can not go more than that. If it is not enough, I am thinking of lowering ther horizontal stabilizer about an inch. Or take dehydral out of the wing. (the wingtips are about three quarters inch higher right now), making it straight across. Anything to lower the center of drag. But I don't want to fix one problem and create another.
