Little puzzled by what's going on here.
Expo is a way of reducing the control sensitivity around centre stick. It should have no connection whatsoever with control interraction.
IMHO, if you have forward/back movement when putting side control in, then you need to look for another problem.
FWIW, I have never used expo on a helicopter. My thinking is that as you move the stick, you get very little initial reaction, which causes you to add more stick. Then the movement suddenly kicks in, so you push the stick the other way in a panic, then you are in an overcontrolling situation.
Far better to leave out the expo, and practice using small control movements.
I generally use 60% rates for the initial flight of a new helicopter. Once I know how sensitive it is, I either go to full rate or adjust the low rate to taste.
Only my thoughts, hope they help
