George,
 
this flywheel is my design, it is steel with the cut outs for balancing. The steel section is 14mm thick, and the ring gear is 250mm diameter, coming off a Metro Geo engine.
I calculated my hp from fuel flow using a BFSC of .5 . May be a little optimistic. Mixture was slightly rich at the tests.
I am running now a Mikuni VM44 carb.

 Richard,
We seem to be singing from the same sheet of music in regard to projected HP at RPM, at optimum performance. So what weight have you got on that flywheel, it seems to be a cut down manual cast flywheel from a past photo. I figured I might need a heavier flywheel than the flexplate and was considering having one of those aftermarket steel ones made and have mounting holes included to suite what ever damper I incorporate.
BTW this is single rotor specific if anyone was confused.
George (down under)
Is anyone flying with a Mazda 13B peripheral port engine?  If so, how is it working?  Can you describe the advantages and disadvantages?

 

Thanks,

 

Bob Rogers
