MVVS 35cc gasser
well on the ground I got a peak RPM of 7590 with a Zinger 20x8 Pro, (7400 tuned for flight),,, but in the air I did not get any more speed or pull from about 70% throttle to full throttle,,
6860 with a 3W 20x8, (tuned around 6600 for flight),,, this prop would pull to full throttle like a hopped-up truck, with the 3W prop my plane was some 20, 25 MPH faster than with the Zinger, and it would climb out faster and a bit higher too,,
the Zinger was just flexing and wasting power, the Zinger is now nailed above my garage door !!

RE: MVVS 35cc gasser
well I now have more time on my MVVS 35cc gasser,, I now get a peak RPM of 7370 with a 3W 20x8, I was tuned at 7000 for flight and the plug was still dark from being to rich, I know I can lean it out another 200,, I'm finding that 300 even 200 RPMs makes a noticeable difference in the top speed on this plane (82" span PA GeeBee Y ARF),,
I would recommend the MVVS, I'm very happey with it..
