<DIV><FONT face=Arial size=2>Ok I ordered an Ultrathrust tuned muffler for my
OS91FX on the Excelleron. Since one of the reasons for building the plane
and picking a setup is for use at pattern primers, and I wanted an
easy straight forward setup. Anyway thinking of changing the 13X8 apc for
a 15X8 APC when I put on the Ultrathrust tuned muffler. They say you get
1k to 1.5K increase in top end by using this product. This should put the
15X8APC at approx the same RPM as the 13X8 on the stock muffler.</FONT></DIV>

<DIV><FONT face=Arial size=2>Any suggestion or am I totally off the wall on this
one?</FONT></DIV>
