[NSRCA-discussion] OS 120 AX

[Jay Marshall]

Started breaking mine in today with 15% Cool Power and a 15x10 prop. Started
right up and turned 8820 RPM if leaned out. Idles WAY down, but not
measured.

I use any 15% two stroke fuel.  The APC 16X8 seems like a good prop to me.
RPM - enough to reach the moon straight up.
