AHH, but Tall Paul, putting the flaperons on a control knob is a great benifit in figureing out exactly where the ailerons should be trimmed. I now have a habit of reducing their total throw down to about 10% and then when flying the plane adjusting the knob slightly to see what difference it makes. If I find a setting I like then its simple to land, see where its at and then adjust the linkage to match.

Zpat, the bad thing is there is no hard a fast rule about exactly what will happen with them slightly raised or lowered. Depends on the style of the plane.
