<tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>> Hi,</span></font></tt>
<br>
<tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>> I am
Mike Harrison, I worked with APC to develop these props. Let </span></font></tt><font
size=2 face="Courier New"><span style='font-size:10.0pt;font-family:"Courier New"'><br>
<tt><font face="Courier New">> me tell you the goal of the prop design.
It is to fly at a moderate</font></tt><br>
<tt><font face="Courier New">> to slow constant speed under the noise limit
but with good pulling </font></tt><br>
<tt><font face="Courier New">> performance. Therefore, regarding the
rpm, the 8000 is about ideal </font></tt><br>
<tt><font face="Courier New">> for that prop, turn it much more and you will
be above the noise limit. </font></tt></span></font> <br>
<tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>> </span></font></tt>
<br>
<tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>> I find
it interesting that you determine whether a prop is adequate </span></font></tt><font
size=2 face="Courier New"><span style='font-size:10.0pt;font-family:"Courier New"'><br>
<tt><font face="Courier New">> by first tacking it. I would think you
would fly it first to see if</font></tt><br>
<tt><font face="Courier New">> it was adequate. I would encourage you
to do that first. The OS </font></tt><br>
<tt><font face="Courier New">> 140 turns it about the same and it flies very
well. </font></tt></span></font><br>
<tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>> </span></font></tt>
<br>
<tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>> The
whole purpose was to develop a prop that would fly at a </span></font></tt><font
size=2 face="Courier New"><span style='font-size:10.0pt;font-family:"Courier New"'><br>
<tt><font face="Courier New">> deliberate pace at about 150 meters to
compete with the electrics. </font></tt></span></font> <br>

is also an 18.5x9.5 which I fly and it turns about 7500 rpm. </span></font></tt><font
