The short answer to your question is; the Mini-500 cruses at 70% power
available at it's operational RPM, which is at 90% of it's total duty
cycle.

Hummm, you or someone else is not being truthful, about the percent power
and RPM's the engine had to run at.

Also, the factory being eager to sell engines for the 500 is not quite what
I heard.

I know who I will believe.
