I mentioned to one of the instructors in my club that I programmed in flaperons and he told me NOT us do that! He said that it would make the airplane more succeptable to tip stalling. I thought that if would provide more lift at the wing tips.
Your instructor is right. Either use flaps or none. Avoid using flaperons. You do not want more lift at the wing tips so they stall first (tip stall). You want the inverse - more lift near the center section. This is why some wings have washout (less angle of attack at the tips) to decrease the chance of tip stalling. Using flaperons will increase the angle of attack at the tips.
