Lee if you offset the elevators to compensate for the ailerons your loops would look like corkscrews. Most of the differences in the aileron trims is due to some slight warpage in the ailerons themselves, mine have some bows, combine that with P-facter from a big prop and a little lateral balance issue and it can turn into all night chase. If it's close trim it, fly it and after you crash it maybe the next one will be better.....just kiddin'.
