I have an MVVS .61 glow engine that I plan to use in a H9 P7 pattern model.

I think it is a long stroke engine.

Can you confirm that and give me some info as to the torque curve of this engine so that I can use the correct prop?

I plan to use a Jett muffler (the red one) so I need to get the rpm range correct for the muffler and for the torque peak.

I expect to have to compromise a bit but want to get as close to optimum as possible.

Thanks,
Jim
