<DIV>Ditto on the extra headshim, 20%, OS-F, EFI bearing, longer pipe, and
propping for 7500 - 7800. I ran the RX and EFI this way fo 5
years. On the RX in particular, what pipe and what length will have a
pretty dramatic effect on the peak power and midrange transition, and to a
lesser extent, the "best" idle mixture (the idle mixture has some effect on
the midrange transition up to about 1/3 throttle). The idle compromise
is usually this - richer is better for spool down and braking, but leaner is
better for midrange transition.</DIV>
<DIV> </DIV>
<DIV>The 15.5-12 4b will work, but vertical is not nearly as good as the 10"
3b or 18.1x10.1 2b.</DIV>

<drmikedds@sbcglobal.net> <BR><BR>> 2 things I recommend are adding
an additional head shim so that there are 2 <BR>> head shims and
lengthening the pipe a couple of inches from the standard <BR>> setup. I
use the OS F plug and 20% pro blend Cool Power. <BR>> We have recently
found the idle needs to be pretty lean. <BR>> I get very strong
performance and very smooth transition. <BR>> One more thing, be sure to
change the rear bearing to the EFI bearing. This <BR>> can be purchased
from Tower Hobbies. <BR>> <BR>> The key to quiet engine performance is
not to trun too much rpm with the <BR>> 18.1x10w. The plane will be very
quiet and have great power if you are <BR>> turning 8000rpm or less.
