I have not tried it, It seems the general rule of thumb is that outboard aelerons dont work well as flaperons. I can say that the rascal loves to take its time settling down. I used to start my approach at least 400 yards out. I wish they would make a kit so real flaps could be added. Personally I felt the roll rate was very slow at max throw.
Anyway.. good luck it is a nice plane ( like every sig arf I have tried)
