What prop dimension have you used for a MVVS/Evolution 45cc engine? I have run mine with 22x8 Menz but this seems a little small.

Status: offline 		Way too much prop. Even 24x8 is too much....23x8 is too much. I bet a Menz 20-10 would get it to 7000 RPM.

I ran my MVVS 45cc today with a Hi-model 24x10 prop (Mentz copy). It turned it at 5300 rpm .
This was a little too much prop.
A 23x8 might be a better prop for it. MVVS warns to let it rew over 750rpm.
