RE: New Version Cermark F-16 1st Flight
The stab incidence will depend on the CG. With the CG at 8" you will need the center of the leading edge of the stabilators to be about 3/16" below the fuselage joint line. At 9" the elevators will trim at about 1/16 below the joint line.
I tried an 11x11 Graupner and a 12x9 APC on my OS 91FX. The 12x9 works a lot better.
By the way 509thBoomer, it flies much better at 8.5 inches than at 7 3/4.
