With the skin hinge ailerons, I wonder about how well the OTOP rolls axially. I know that this often an issue with the larger CompARF and similar skin hinged scale aerobats.

Does the OTOP roll very axially?
Did you have to dial in a large amount of differential aileron? If not, what do you do to get truly axial rolls?

And for those of you who have flown others as well, what flies better, OTOP, Temptation, Lazulite, Focus I, II, others?
