smh20502,

Thanks for your answer. It seems that there isn't to many people with my version of the Seagull Edge 540.

The wing incidence is the angle of atack that the wing has at the fuselage root. Since this is defined by the chord of the wing profile and the line of flight of the fuselage (datum line), the wing incidence doesn't have nothing to do with installing the servos.

You mus be talking about trimming the aircraft. For that you need the servos.
