i have a set of "French curves" they have a bunch of different shapes to them ...i use those when drawing my own airfoils.somtimes i start with a real airfoil,but yeah some times you need to change them to fit gear/servo ect. and taylor your flight qualities. i agree with John on a rounded LE. i tried a sharp one once ...it did some crazy stuff.
