Just wanted to compare this engine to other in its range. In particular Webra .50, Irvine .53, OS .50.

Let me know RPM at what prop and what fuel. I am mainly concerned with fun-fly props.

Mine:

MVVS .49 Mini-Tuned pipe and FAI fuel(80% Methenol, 20% castor, 0% nitro)
11x4 14,500
12.25X3.75 12,500

This is a new engine. These figures were on the second tank.

Thanks,
Gregg
