Nick,

I didn't realize that people are flying so "aggressively" with margin near zero for all classes. I have been flying 25 to 40% with my F1Ls. What margins do you use for your F1D and ministick?

Also, what are people using for the definition of the Neutral Point? In Bernie Hunt's program, he calls it "Reg's Neutral Point". Does anyone know who is Reg?
