RE: Viper Jet 2M Pointers/ tips.
I am about to maiden my 2M Viper, CG is 20 mm forward of the main spar. I have searched here, but not found whether or not people are mixing in any (presumably) down elevator with flap extension. My flaps come down 35 and 65 mm.
Should I mix in some down elevator with flap extension, and if so, how much?
