<DIV><FONT face=Arial size=2>The props Dr Mike are talking about work really
well with the OS 1.40. Its best to get the prop you feel comfortable with
in speed and then trim the airplane as different props can change certain trim
attitudes. </FONT><FONT face=Arial size=2>If you trim the plane and then
change props be prepared to retrim. I really like the 18.1x10W Apc. FWIW.

up that I have and the engine is performing very well at all positions. I
believe I could do a cuban 8 without getting above 5/8 throttle. I may try the
18.1 x 10 two blade when I have the opportunity. At the moment I'm mostly
doing some fine tuning on the trim, mixing and balance. Plus my thumbs are
used to the more classic pattern ships like Daddy Rabbit, Intruder and Dirty
Birdy. Flying this Focus is so awesome and graceful --- well it should be once
I get my footing! Ha! <BR><BR>

<DIV><FONT face=Arial size=2>I find the 18.1x10 or 10w or 11 to be the best
performance prop out there. Regarding speed, I consider speed the
enemy. Go for a very medium paced steady flow with very good
vertical. The OS should give about 7700 rpm with the 10 pitch.
Fly 1/2 throttle or less on straight and level. If you have transition
issues with the engine, the pipe is too short. The exhaust should be
almost clear, a very light amber. If it is darker, too lean, green is
too rich. I have 3 stock OS 1.4 with good bearings. They all
transition effortlessly and smoothly. They have unlimited
vertical. My plane is big and weighs 11 lbs.</FONT></DIV><FONT

<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

wondering if I use 15% Cool Power, F plug and change to the 10 pitch prop
would I be better off...? </DIV>

<DIV>I'm running an os 1.40 inverted with 25% pro pattern and
sometimes during hot weather 30% heli. Is an A5 OS plug my best choice
based on some of you guys experience? </DIV></DIV>
