Thanks Dar...that was the only prop I tried on it, and was during break-in. I don't usually use mas props (APC's ) but I figured the 11 X 5 would be a light load for break-in.
That r.p.m. was only peaked for as long as it took to get a tach reading, and I just ran it a few times and put it back in the box (after adding after-run oil of course )

14,400 huh? I'll see which prop it takes to get the r.p.m. close to that.


I have a Webra .50 w/ Ultra Thrust muffler (did the sleeve mods on that one too ) that will turn an APC 10 X 8 at close to 16,000 on 15%...what would that figure out to be?

(I had a problem with the calculator too )
