So , the Hitec servos are worth buying to avoid the fit issues in the wing. They are reasonable cost. Can you explain more about 11 mm vs 13 mm ? Regarding the wing servo mounting , as I uderstand it all the servos are mounted the same and the flaps would be right but one of the ailerons would have to be run through another channel to reverse it. This would make it possible to ad crow, flaperon etc. . So it is also going to require custom wiring extensions into the wings. I alterted my buddy and he should be reading this thread soon. Well, I have the order qued up at Espirit but have not put in the credit card yet. Thanks for all your help, the manual is as you said, in need of words and photos.
