<DIV><FONT face=Arial size=2>I run the OS91fx under 8000. The larger props are more efficient and the noise level is comparatively very nice. I don't think I am giving up much in the way of thrust horsepower. Nat</FONT></DIV>

<DIV><BR></DIV>
<DIV>I am using a 14x8 on a Hano type pipe (7.5# Desire) which gives 10,500 RPM. I had problems setting a longer pipe for for a 14x10, which was the target prop at 9,000 RPM. I am going to try a Perry pump set up, with the 13.8X10 4B. I need to change out the rear bearing soon (250+ flts). </DIV>
<DIV>A while back, I read somewhere that the 91FX likes to rev around 10,000, given it,s over square stroke and porting configuration. </DIV>
