GP Ultimate wing incidence
My experience with the ultimate is that even with a .46 FX on front (not the biggest engine), it seems to do nothing but climb with 0-0-0. I need to dial in alot of down elevator for it to fly straight, (Once having done that the airplane still flys great!) when i get some time i want to adjust the incidence to negative on the top wing. To change the incidence of a biplane is quite simple for the top wing atleast, just place washers in between the bolts and the wing. Hope this helps.
