I think I know the answer to this question, but I thought it would be in interesting discussion and might be valuable for people considering them.

I've got a WM .45 size P-51 that's ready to fly. Since the plane has dual aileron servos and I've got a computer radio, I have a choice of using flaperons or not. I've seen some people say they are ok, others seem neutral, and still more say do not use them on a tapered wing. So, let's vote and give reasons why.
