Hey, experimentation is what it's all about-within reason, of course! I think R8893 has pretty well summed up this concept, but if it doesn't compromise safety or your wallet too much, EXPERIMENT!
My friend Pete ("jmupilot" on here) once made a plane with a "T" tail , (stab sitting on top of the vertical stab), and it was a "full flying stab". No elevators, the whole thing changed incidence. I saw the first flight of it. The linkage wasn't quite stiff enough to hold the stresses imposed on the stab when it changed incidence. It would fly fine up to a certain speed, then the stab would start occillating up and down at a very rapid rate, and the plane responded accordingly, jumping up and down about 5ft. very quickly. Cutting the power would stop the problem. It was funny as hell to watch. I was amazed that everything stayed together in the plane. Pete and I also had a joint space shuttle combo we flew successfully. I flew a Telemaster with his shuttle atop it, complete with Estes rocket assisted take off. I'd take him to altitude, disconnect and he would fly the shuttle back. We even have that on video tape. Two successful flights. We won't talk about the third. Pete also has a plane with forward swept wings, but I think the ailerons are on the back of the wing. It appears to fly well. Hey, go for it!
