RE: Flaperons?
One thing many have a problem remembering is that a stall, depending on how you define it is NOT a bad thing. AS LONG AS the stall is symmetrical. Its only when the wingtips stall while the inner wing or opposite wing is creating far more lift that problems occur.
Technically a stall in and of itself is NOT a problem. The wing is still "flying", just very inefficiently. Most people think that when a wing is "stalled" it is providing no lift. This is not true. What is true is that the separation bubble has broken lowering the lift coefficient.
All this talk of CG is so much garbage really. All that is showing is how much tail authority one has on their model.
PS. Dual function ailerons are a wonderful thing. Flip the switch upon landing causing your ailerons to ONLY go UP and not down will prevent wing stall. Likewise add in the function that the ailerons "center" is moved upwards as well is also a sweet function.
PPS. All "real" computer controlled airplanes use spoilerons at low speed. When mechanically linked control systems have more limitations regarding their use, though possible through the use of CAMs.
