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

much more and you will be above the noise limit.

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
