A lot of the problem with airfoil selection is that there are already thousands of them. Yes, there's probably a near perfect one for your pet project, but actually finding it is VERY tedious. If anyone could point to (or create!) a database where you can search based on min/max Cl, L/D, Cm etc, a lot of us would be eternally grateful.
http://airfoiltools.com/ It doesn't really give you the search function (IIRC), but you can navigate through "similar" airfoils. E.g if you start with a low Cm high Cl airfoil it will show you a list of similar ones then choose the one you like best, rinse and repeat.
