Rake of a formula fin
May be a dumb question , but I read some brands measure rake at the trailing edge and some at the leading edge. What will be the good rake for a HWR at the leading and trailing adge. Someone with experience?

Leading edge... 4 degrees is pretty close to normal.

rake in degrees of the leading edge depends to the fin outline. A more triangle outline has more degrees at the leading edge than a rectangular outline meaning the same rake. So be careful if you compare different outlines!
But its true the range of the angle of the leading edge is from 2 to 6 deg. more power at 2 deg, more downwind speed at 6 br pfaffi www.pfaffi.at |
