<DIV><FONT face=Arial size=2>Based on all other models... our pattern planes are
by far the quitest airplanes in the air. I have seen a few IMAC's that
have the noise down some but they still get a good prop rip at speed.
The .15 to .60 size engines make an iratating high pitch whine.</FONT></DIV>
<DIV><FONT face=Arial size=2> Why is it that the pattern planes are some of
the quietest yet we are still pressed for lowering the db even
more?</FONT></DIV>

<DIV>Has anyone measured the sound levels of the larger two strokes
turning the big props? We measured a YS140DZ with ES pipe turning a
17X12 APC and came up with 96dB, right on the limit. Just
curious.</DIV><BR><BR>Bob Kane<BR><A
