Hi,

I've been following this thread and thanks for all I have learned. I have a practical case that I'd like to ask about.

I've been into 1/2a pylon racing for about three years and scratch build my racers. Wings are 200 sq. in using MH33 foil. Airplanes are conventional hi wing and conventional tail. V tails look great but are harder to build and trim. And I doubt that the speed range we operate in 80-90 mph will afford much benefit for the V tail. Weight ready to fly is 11-12 oz. Wing span is 32-38".

My question is: Given my application, Where would my optimum angle of attack be for the foil I'm using? I have noticed some different flight/glide characeristics between airplanes and have wondered if I'm getting the AOA right. I suspect that the geometric AOA is not the optimal. Your thoughts and comments are solicited and appreciated. Best regards, Jeff.....
