Assuming you have checked the mechanical part acc. to the other thread and then sub-trimmed within reasonable amounts to get the flaperons to neutral:
If one servo (surface) moves more than the other you might want to eg. decrease the END POINT of the one with most throw. Scroll to either CH1 or 6 and move the ail stick in desired direction and change the value while watching the surface movement.
To acieve the desired amounts of travel you also might want to play with the numbers in the flaperon menu (ail1, ail2 with their L and R numbers).
And if you dont want to mess up a working setup, copy the model to another, empty, memory (under the MDL-SEL menu) and then play with the numbers. (And some more ifs: newbie & electric model - play without any propeller mounted).
The SERVO menu usually is a good help also, to see where different numbers and mixes take the servo(s).
