RE: Knife edge trimming question
Tom, I want to wish you luck with the Genesis. I understand a few modifications were done since the original production runs, so hopefully you will have better luck than we did with it. Unfortunately there are still inherent problems with the Genesis design that prevent it from achieving a truly mix-free setup (just ask the Chicago Mafia about their experiences) If you get it down to 5-7% rudder - up elevator (and that's all), you're doing really well. Everyone I know who has ever flown a Genesis complains that it drops the nose on rudder input.
Dick, I've had many a conversation with Bryan regarding aerodynamics and trimming (in fact, I edited the K-Factor article for him), and he does not disagree that the angle of attack required to produce lift at a given speed does not change regardless of whether using a 0-0 setup or a positive incidence setup. One thing I have seen and felt from flying his designs with his setups is that his airplanes roll, snap, spin, and lock into a line better than any other planes I've ever seen or flown, with less effort by the pilot, and throughout the maneuvering speed range. Whether at 1/4 or 3/4 throttle, the plane performs the same, only requiring the pilot to adjust the timing of control inputs. I wouldn't knock a 0-0 setup, to each his own... but I'd never fly one again after flying Bryan's.
