It is caused by the small gap between the inboard tip of the aileron and the wing and the fact that those tips are not capped like they would be on a traditional arf.

yes you are right, its basically the gap on the ailerons, the air whistles over it and through it to the tips, i believe. its not just in roll, with my 33% electric, you get it when pulling up
