RE: Swing Wing Aileron Function
If you're using a computer radio, you can program a jackscrew servo like those used for R/C sailboats to move a ballast weight to keep CG where you need it when the wing swings. I would use stabilators and forget the ailerons. A friend and I are working on a high-speed design, and have modeled our concept on RealFlight, and the Stabilators seem to work for it, and they're the ONLY moveable control surfaces on the airframe!
