Hello Mark Almost all the profiles have a moment of negative pich, that is to say that have a dive moment in cruise flight. In the gliders is used the call negative aileron, movement that takes both ailerons to about 8ยบ up and prevents to have to compensate this moment in the empenaje. The Pollywagen has commands with this possibility (and I copy it for my KR-2). Probably your ailerons go naturally to the corrected position. My modest contribution to the general confusion. Eduardo
