10.0pt;font-family:Arial;color:navy'>All the 18.1 props run well. Comparing
them to the 3 bladers, the 18.1s are louder and heavier. On the ground
the 18.1x10 is about the same load as a 15.75-11 3b, but the 18.1x10 will
unload more in the air. Depending on throttle technique, drag of plane,
pipe and pipe length, either prop might be easier to fly constant speed –
most guys find the 3b tends to be more constant speed as it does not unload as
much as the 2b. Exception is when the 3b is bogging the motor, and the
plane slows in an upline (if any prop is bogging the motor, reduce prop size,
add nitro, or lengthen the pipe). If the plane is a little quick now, the
15.75-10 3b will slow it down, as will lengthening the pipe. Reducing the
nitro will also slow the plane down, but the sweetspots for the needles will be
a little narrower (I agree with leaving the nitro in).<o:p></o:p></span></font></p>

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. If you trim the plane and then change
props be prepared to retrim. I really like the 18.1x10W Apc. FWIW. run on

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

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
