Flew one with aileron mods last week, indoors. Each aileron had its own servo embedded in the foam wing. No special redesign of the factory wing and the servo wires were taped to the bottom of the "concave" wing, span-wise. Flew very well but only have poor digital image of it in the air; otherwise would have provided detail shot of aileron installation. Maybe, I can get you a good shot if the owner brings it to our club meeting in two days; if you are interested? Meanwhile, I will do some 3D aeroelastic computer modeling using normal mode beam simulation to determine what the tensile sigma max. levels are in that foam wing in a 3G stall and spin maneuver. Not to bad for an old Mfg. Eng? Just kidding!
