I have converted at least 20, all ran 8800 or better...The stock muffler cuts rpm to 8200..No muffler, 9000..Slimline Pitts, 8500, Abell, 8800..Changing altitude to 1000 feet makes no difference...I'm going to Phoenix Sunday, will tach a few more props....The Mejzlik 18-6 is the prop used for the tests, others turn slower...
A lot of RC'ers say that Zenoahs can't be hand started either, doesn't mean they won't....[sm=bananahead.gif]
