How to fly a Cub (Hanagar 9 1/5 scale full-wing) in this case. I know,,, use the rudder!!! and I do.

But the question is: is there some other techniques/set-ups that might improve the tracking in a turn. Does anyone raise up both ailerons, say 2-3mm? to improve washout?
Does anyone limit aileron travel, say more up than down so there is a spoiler effect on once side?

Sometimes I have to add opposite aileron to help hold the nose up in a turn. I'm looking for ideas to improve J3 Cub flying.
Thanks
