<DIV><FONT face=Arial size=2>Not that it's any help, but I have been running the
same setup you have with the same numbers (prop, pipe length and RPM) and
have not been blowing plugs. I have been running Cool Power 15% and an MC carb.

<DIV><FONT face=Arial size=2>I have a Greve pipe, and it's 29 1/2 to rear

PTSIZE="10" FAMILY="SANSSERIF">Bill, is your pipe set short? The pipe I use
(Hatori) has the first deflector plate located at 23.75" from the glow plug,
straight line or around 24.5" along the centerline of the header. Are you
running a large enough prop to keep rpm at around 78-8000 or so? <BR><BR>I
typically will run one type F plug per 150 runs in the 145, using a 20%
nitro and 19% oil blend. My fuel blend is a 50:50 mix of 10%cool power
and 30% heli cool power. The large head of the Webra (large heat sink) just
about requires the hot F type plug to run right. I've had limited success
running other plugs in the engine.<BR><BR>hope that helps you
