Online aerofoil profiles?

Question

i am building a little (no bigger than a foot) glider with a little motor. it is not going to go very fast so i need an aerofoil profile that works optimally at low speeds.

Induced drag(http://en.wikipedia.org/wiki/image:... on most aerofoils decreases with speed, and so that is my main problem. i need the best lift and the lowest induced drag at the lowest speed.

can you provide a link to a list of good aerofoils, or maybe provide (x,y) co-ordinates so i can plot it out.

i have come across a site, http://www.pdas.com/avd.htm... that has thousands of aerofoils in co-ordinate (x,y) form, but like i said, i dont know which one to use. thanks for any help.

Answer 1

This NASA site lets you see choices with results

this one treats model wings

if the national air model organization is still around (from my youth) they should have something

Answer 2

A glider with an engine isn't a glider. You would be better off building a few kits first and studying Aeronautical Engineering before trying to design an aerofoil without any knowledge.
