RE: Small Spitfire Engines
My first engine was not a Spitzy 0.045, and my first control line airplane was not an A. J. Firebaby.
But that combination was my first successful control line airplane. Flew the pooh out of it with the metal propellor. I used the engine's tank instead of the supplied bladder tank. Didn'y have a long engine run, but it was long enough to enjoy.
