<DIV class=AOLPlainTextBody id=AOLMsgPart_0_0204c2e4-6fc0-46e0-841d-281259482a47><PRE><TT>Hi Bill,
Set it up for 24" from the baffle to the glow plug (<SPAN class=correction id="">IIRC</SPAN> the baffle
is 13.5" back from the front of the pipe). That length gives a nice
amount of boost without being peaky whether you run 15% <SPAN class=correction id="">nitro</SPAN> or
Magnum #1. With an <SPAN class=correction id="">APC</SPAN> 17x12 you should see ~8200 <SPAN class=correction id="">rpm</SPAN> +/- 200 <SPAN class=correction id="">rpm</SPAN>
depending on what <SPAN class=correction id="">nitro</SPAN> and whose fuel you choose. Be aware that if
the motor is new the idle won't be too great until you get >15 or 20
flights on it. The top end numbers won't come into their own until
about then either. The sleeve on the <SPAN class=correction id="">Webra's</SPAN> is really hard and it
takes 20+ flights for it to really "settle in" and then it just gets
better and better.
Just my $0.02 (not that I'd know anything about <SPAN class=correction id="">Webra's</SPAN>...)
