Hello my problem is that i have to make a constant right effort on the stick to not take roll. The plane seem to roll alone left. I saw that my pitch control surface is not from each side. I try to be more clear if you put the control surface on a horizontal plan the left part is more high than the right part as the control surface was bent.
Or is it to cancel the engine couple ?
How do you control the setting of the flaperon ? and how do you set it.
My idea is if the plane want to turn left i'll put the left one a little bit lower and the right higher ? I'm true no ?

Thanks, for local flight will be ok but for long navigation i'll be a body builder
