You can opent he back cover of the TX. There is a little screw on the stick gimbal for adjusting the spring tension on the stick. Try increasing the tension on the aileron direction and maybe decresing tension a little on the elevator. that will reduce your tendancy to input aileron with elevator.

I have the opposite tendancy... I tend to input elevator with aileron... and I tightened the elevator and loosened the aileron... got rid of 90% of my inadvertant elevator inputs. (I have no problem keeping from inputing aileron with elevator.)


It is also possible that you are inputting EXCESS elevator. this can lead to a high speed stall, and a wing will "drop" That can give your described appx 45 deg roll in a loop. (more often it gives a snap-roll out of the loop at the top...)

Another potential problem is not enterng the loop level in the first place. It may LOOK level to you, but I bet it always seems to roll outward. If it does that from both directions... your idea of level has the inboard wing high.
