Magnum wing profile
welllllll... you get a pen and go Zipppppppppp
and then you go back again and do a curved Zipppppppp on top.
it might be a actual aero... i did have a wing in half so i could had shown you, but i glued it back together.
its basicaly flat bottomed like a clark Y or sommit similar, pointed ever so slightly down to make it slightly semi, like straight line from te to Le
taking it right from your plane should be easy, just copy the fuz cut out, and draw a straight line under it
