You bet it was.

It's the easiest way to have the top aileron move exactly in sync with the lower aileron. The hardware provided by the ARF mfg, and the rigging it provides will result in the top aileron moving a different amount than the lower. It moves somewhat less going up, and even less going down when you use their hookup.

Truth is, the airplane flies great with the provided hardware. I figured my would fly "greater".

I originally used my concept on the little 40size Ultimate. A couple of them that I've seen fly with the "unequal" setup were supposed to be sensitive to tip stall. And you had to watch out to keep the speed up on landings or they might drop a wing. Mine does neither. Matter of fact, I've never had mine drop a wing yet and I'm flying the heck out of it. I frankly don't know why the wings are still on it. I figured it's worth the effort for any of them since it actually takes less effort to do it.

Big biplanes with 4 servos will have all 4 ailerons working in sync. I've seen instructions that emphasized that the builder needed to take care that all 4 ailerons moved exactly the same. I figured it didn't make sense to have my little ones work any other way. And I knew how to do that. I'm surprised nobody else has ever made any noise about it.
