Re: Formula for percentage arcs anyone?

Does anyone have Simplex as an arc in DAT form? All I have found are flat bottom with sharp pointy LE - That is not what we'd fly in say LPP.

I also realized this morning - I shouldn't build late at night when I am tired. Changing the chord on the arc % will change the radius. So the %arc template needs to match the chord. The ones I was comparing were sufficiently different chordwise that I noticed it. And that is where I made the mistake. I'll be making new templates tonight for the proper chord.

Regards.
