Keith,

That's a great suggestion. Thanks for steering us to that thread.


Did you say that you still have some of the lightweight flywheels from your BME-24 design?
I'm wondering if they would fit this engine and make for an easy weight reduction on this engine.

Do you have prop hubs that would fit after removing the flywheel (for a glow conversion) on the BME 24?
I'm wondering if that type of hub would also fit these Mac25 engines. The major shaft diameter is .474" and the threads appear to be M8 X 1. I have no idea how to measure the taper.

Thanks again for your input.
