Default RE: incidence

Sparky,

Is there any way you could shorten the forward attach points of the upper wing struts? If you could get the top wing to a slightly less positive incidence than the bottom wing, you might solve much of the problem. I built a RTC Giant Aeromaster that had the struts and attach points pre-set by the manufacturer. All incidences checked per the instructions, but it required a lot of nose down trim to fly. I shimmed the upper wing to reduce the incidence by 1 degree and solved the problem. If all else fails, try drooping all ailerons a couple of degrees. This will move the center of lift back a little on the wings and help lower the nose. Good luck.
