Hello everyone.

I have been flying an stick kind of plane with a converted Mitsubishi 33cc

With a 16x6 propeller I was getting 8,000 RPM but not much climbing power

With a 17x6 It gets better

I tried this last weekend a 18x6 and while RPM´s goes down to 6,400 the plane behaves much better in the air with much more climbing power.

The question is should I try a 19x8 MAS Scimitar prop or would that be too much for a 33cc converted engine?

Thanks everyone for your help.

VÃ*ctor.
