an easy way to try and stop this is to center both ailerons and then use subtrim to drop both about 3/32 of an inch,it will only make a small difference in flying the plane but will make a big difference in landing and slow speed handling.i had to do this on my 1/3 rd cap 580 and it made a enjoyable plane out of it.and at 26 pounds it ain't too heavy for the wing
