Improved version of F7U. Reflexed airoil, larger elevons, dihedral in outer panels. Still not ready for prime time. Further redesign in the works.

It looks light as a feather!

Unfortunately, a bit too light. The model,except for the wing spars, is made of "contest grade" wood (4-6 pound/cu ft). While it did improve the climb rate over the original version it turned out to be so fragile that I could not make adjustments without breaking something. It also could not take contact with walls and fixtures with no damage like the original. The definitive version has a few changes to the structure and all the strip stock is 8-10 pound wood like the wing spars. I'm working on a prop design that will give as much thrust but be lighter than the Peck prop I have been using.
