Old Larry,

Back in the late 80's or early 90's when the Dragon Lady was introduced. it was available in two sizes as an almost ready to cover (ARC). The larger one is now available as an ARF .90 to 1.20 size. The smaller one was what I would have called a .40 to .50 size plane. My larger one was first flown with a Saito 1.30 twin and flew very well till the time I took off with my antenna collapsed and it flew on it's own into the side of a garage about a half mile away. After rebuild it has been flying very ably with an OS 90 four stroke.
The idea of putting flaps on a plane like this strikes me as somewhat funny as does the idea of using two aileron servos. Just increased complexity for no increase in performance. Any standard servo will throw those ailerons as far as you want........RJ
