Information gained from the NASA Airborne Trailblazer project

Here's a historical document on a NASA page, which includes high lift info

Here's another NASA report on slotted flaps, downwash, etc.

An article from the Centennial of Flight Commission page

A great online source for all kinds of aerodynamic information. Check it out!

Here's the site of Anders Johnson, maker of the "Lego Flap Hinge" model

Check out the "Short Takeoff and Landing" page at Fubar Hill. Lots of basic aerodynamic information, as well as ideas for hinging your flaps and slats.
