Ya... my buddy has a problem with entering loops and Immelmans with one wing a bit low... MAJOR corkscrew to the right. Sometimes worse than others, terrible in a cross-wind, but it's not consistent enough to pin down to a problem with the airframe, and he is able to make a good one.
It is VERY easy to pull or push the aileron when pulling back elevator... I tend to roll to the left, as I fly with my thumbs on top of the sticks.
