wow xander you are right. that plane looks very awesome.
Not only does it look awesome, but it is a hell of a lot of fun to fly.

The Pitts S2B is an unlimited class biplane. It will take quite a few Gs, and has inverted fuel, so you can fly upside down until the cows come home (most small aircraft use gravity to get fuel and oil from the tanks to the engine -- thus, when you fly upside down, or inverted, the fuel can no longer get to the engine. The S2B has devices to allow you to fly upside down until you run out of fuel -- thus, and inverted fuel system). That, and a huge engine, make the Pitts S2B one of the greatest airplanes every built. They are so much fun.
