Hi Cholo!

Fins are designed to maximize lift by a minimum of drag. Out of this is the special Tip shape. Additional to reduce the twist by outline design and not only by twist reinforcement. The used laminar profile is one of the fastest and non critical. Find some lift/drag diagram and profile views on my starting page.

Cheers pfaffi
