Like Ehab said. I feel that the turn feels smoother, especially at the start, and a smoother roll rate. Here is the breakdown in the planes and number of flights with ailerons/elevon mix

JL f-18C - 5 flights

SM F-18C- 5 flights

Tam's F-18F- 4 flights

Air Magic F-15C- 1 flight

I don't think I will be going back to just aileron anytime soon. I left the aileron throws at the recommended throws and just "eyeballed" the elevons. I'm thinking about trying it with the bandit and kingcat! [X(]
