A simple way to add differential without complex radio tuning is to set the zero position on your aileron servo control horns leaning towards the front of the wing slightly... about 10 degrees or just move it forward one or 2 splines on the shaft that way the aileron will physically move a greater distance when the aileron moves upwards and a shorter distance when it goes down... If you are having a little trouble understanding the principal... see me down at the field next time and I will show you how easy it is to set up.
