I left my computer on while I was at work, sorry about that. It was designed to run at 3500rpm WOT and 40 hp. NA. We do have a supercharger for it, but it wasnt needed for the manufacturers specifications.

We can do it Natural Fuels or Propane. She runs about 5 acres per hour, if in brush about 3-3.5 acres per hour depending on the brush.

We designed the exhaust so that it would be quiet in apartment complexes.

Last year at revolution rotary we were caught on film popping wheelies!

It has 40HP at like 3500 RPM. Perfect for mowing lawns. It's also got propane, but is naturally aspirated as far as I know.

Kathy, I'm gathering all the parts I'll need to build my '6.5B'. I think all I'll need to get from your shop is the shortened tension bolts and the E shaft. Or could I shorten and cut new threads on my own? How much for a set? Also, how much for the E shaft?

I assume my rotating assembly will function together ok. They consist of:

'74-'85 (1757) front counterweight

'74-'85 rotor

and '76-'85 rear counterweight

They're all meant to run together, so again, I'm assuming they'll work in a single rotor engine.

Not sure as we perfectly balance each unit. Each rotor can be slightly off and balancve is extremely important in a one rotor.
