RE: OPS engines for BPA Pattern Ships
pitstop000.
See the post of flying the old ones:
That engine is almost too pretty to put in a plane! What do you have planned for it?
Our pictures all do show a RC carburetor, the engine with the pipe isn't a RC, so maybe for race applications.
No point, enough pictures to warn the people to look for the right (modern) OPS if there is still one for pattern.
