I've built two planes, and working on the third one right now. A flat-plate delta with twin rudders didn't fly, but that was due to poor design and low power. I put more power on it and it flew, but it wasn't all that much fun.

The second plane (shown here) is a mid-winged sportster and I just flew it the first time today. It uses an 010 and a 7-cell pack of 350mah batts. Weighs 9 oz and flies like a champ!

The third plane (in the works) is a Cessna-ish looking bird. Fuselage is done, the wings will only take about 20-30 minutes. You can just turn planes out so fast with this stuff it's mind-numbing.
