Luke,

The Cub on the left was just referred to as the "OK Cub". Its displacement is .049, although it does not say so like the later engines. They also made an .074 version, but it has .074 stamped on the bottom of the crankcase. The tanks, by the way, were for FF.

My first engine powered model was a Scientific Little Bipe, powered by an OK Cub. It got a few laps on that small tank. BTW, I did not build that first Little Bipe, I traded my BB gun for it, ready to fly.

My first Cub .049B had the type string starter you show on the OK Cub, but it was fitted behind the prop and facing the other direction. It came on a Comet Sabre44.

As to the reedie. When Dick Sarpolus designed most of those planes, I think all the current reedies except the Black Widow used single bypass porting and a low compression glow head, so they put out much less power than the BW.

Good luck with those planes.
