Just a couple of quick clarifications...

My prototype has 7" Sullivan wheels (6" wheels looked too small), and the wing chord is over 25 inches. Total wing area is over 23 square FEET.

I'm pretty sure Dr. Rick's model that was on display at Toledo has a DA-100 in the nose, but could be mistaken. I know it won 2nd in Sport Monoplane and 3rd in Monokote!

Yeah, a GT-80 would be an excellent match for the model.
