She is running properly, just not like a Cox 1/2A!

Gotta love that needle valve. She also looks to have the best throttle I have ever seen on a Cox Baby Bee. I think this conversion might finally make the Cox a practical power source for a toy airplane. This looks like it belongs in the same category as the ZDE (Zero Displacement Engine).
