I would try it, and see if you like it. If you already have 2 aileron servos installed, what do you have to loose? I just built a Cessna 177 on Floats, and set it up with flaperons. I simply used 2 servo extensions instead of a y-harness on the aileron servos. Other than a little bit of time on the radio programing, I figured there was no harm in trying it. I only plan on using them to slow the plane down on landings, so I set them up using a switch. Now I can simply turn them on and off with ease. I haven't tried it yet, but I'll try anything once.
