<DIV><BR>My plane is equipped with an OS 140RX with the OS Stainless
Steel sealed rear bearing, Carl Mueller header and Greve pipe. Motor
mount is a Gator soft mount. Tru Turn 3 blade FAI spinner with an APC
15.75 x 11 3 blade prop. (I have a 10 pitch prop also.) Using 25% Pro Pattern
the plane will cover a lot of real estate quickly! I'm wondering if I
use 15% Cool Power, F plug and change to the 10 pitch prop would I be better
off...? </DIV>
