VG, you raise a good point. Even if the Pacer in this case uses strip ailerons some reduction in response could be gained by cutting away the outer 2 to 3 inches of the strip and securing it solidly to the wing. That would produce a part of the wing out at the tips that tends to resist the aileron action by damping some of the rolling action.

But at the same time the Pacer is intended as an aerobatic model. So why someone would want to do anything to reduce the roll rate is a mystery to me On a racer then sure. But the Pacer isn't a racer. It's easier to just learn to use very small stick movements at high speed so you maintain the slower speed control response you want.
