So JJ, your design?


No, I just copied the work that Bob Salvo and Don Kroesch have been doing for
years now. They both did well with modified Genesis's at the Seniors this year
and Bob took 6th, beating all other standard class ships. Old JJ was on the mod
in a heard-beat. It works by eliminating the reflex in the airfoil for the
first 13 inches and then carries a straight line on up the fuselage so that the
air sees only a straight line from high camber point on back to the trailing
edge. The Genesis has been troubled by separation in this area. We were able to
control it with angled vortex generators (12 of them) but they produced quite a
bit of drag, especially at higher speed. My ship will now thermal at 45 knots,
feels sloppy at 42 and stalls (mild) at 40.

So, now she climbs well and has always run well.
