<DIV><FONT face=Arial size=2>I can run my Aeroslave pipe a little shorter on the
two blades then I can with your re-pitched three blade on the OS 1.40. But
other pipes have totally different lengths and sweet spots. To get the
three blade prop to work properly with my set up I have to lengthen the pipe
about and 1" more then a two blade to get midrange transition and downline
braking to work properly. </FONT></DIV>

<DIV>It is nice that we have several very good options available for exhaust
systems.</DIV>
<DIV> </DIV>
<DIV>With regard to tuned pipes, to truly evaluate the capability of the pipe,
they do need to be tuned. And how they are tuned is often different for
different users depending on priorities for power, torque, sensitivity, etc -
to say nothing of matching the tune length to airframe drag and weight,
prop, flight style, etc. Simply plugging the pipe onto the end of a
header is rarely going to yield the best performance for that pipe.
Similarly, making comparisons between different pipes that have not been tuned
is not much more than a chance comparison. Granted, some pipes have a
broader sweet spot, but they all benefit from proper tuning.</DIV>

<DIV>I think when it comes between the aeroslave and the ES pipe, it's
personal preference. With some notable but subtle differences.</DIV>
<DIV> </DIV>
<DIV>Here's what I noticed:</DIV>
<DIV> </DIV>
<DIV>The ES 2C140M80 pipe I use is 3.2 ozs, the Aeroslave is right at 3
ozs. it's pretty much a wash.</DIV>
<DIV> </DIV>
<DIV>The transition is bit little smoother on the ES. </DIV>
<DIV> </DIV>
<DIV>The Aeroslave pipe gives about 100 rpm more on the top end. </DIV>
<DIV> </DIV>
<DIV>(both above using standard length header, no cutting and tuning).
</DIV>
<DIV> </DIV>
<DIV>The Aeroslave costs less, but has been difficult to get in the past.
I believe that may no longer be an issue. </DIV>
<DIV> </DIV>
<DIV>The ES is much more easy on the eyes.</DIV>
<DIV> </DIV>
<DIV>The Aeroslave is physically smaller, and could fit better in tight
installations. I've found this to be true on a few applications.</DIV>
<DIV> </DIV>
<DIV>The ES (for me) has proven very very durable. I've never worn one
out, ever. I have one with almost 2000 flights on it. It was involved in a
crash before I got it, The airplane was completely destroyed, head in full
speed...the pipe wasn't scratched. It only had about 50 flights before the
crash.</DIV>
<DIV> </DIV>
<DIV>Also Ed Skorepa has been very good to me service and price-wise, so I
suppose there's some loyalty involved. Lance has also been great to me,
and so I also am running an Aeroslave in my older Black Magic prototype
now. </DIV>
<DIV> </DIV>
<DIV>So, I run both. The ES is more "bling" and a little smoother, the
Aeroslave is more business-like and stronger on the top end but stumbles
just a tad in the mid range. </DIV>
<DIV> </DIV>
<DIV>I'd run either in a heartbeat. I just slightly prefer the ES for my
newer stuff. You can't go wrong with either.</DIV>
<DIV> </DIV>
<DIV>Or should we spark up a rivalry like OS vs YS, JR vs Futaba,
Composite vs wood, etc? That could be entertaining =)</DIV>
<DIV> </DIV>

Pipe for OS 140RX</DIV>
<DIV><BR></DIV>
<DIV>I've run most of the pipes available in the past couple years on
both the OS (RX and EFI) and Webra (145 and 160). The "best" pipe
depends on how you prioritize power, throttle response, noise, weight,
and price. If I needed to buy a pipe today, I'd go with the
Aeroslave as I believe it is best or very close to best in all the
categories I listed.</DIV>
