<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Long ago, right after dirt was invented, we used to fly by frequency. This was back before the 50 channels we have now. There were seven 72 MHz frequencies, as I remember (if I'm wrong, someone will jump in and correct me). Contests were flown with, for example, all the pilots on 72.080 MHz flying in a row, regardless of what class they flew. It was awkward for the judges, because they would see pilots in different classes flying in front of them helter skelter. We started flying by class in the southeast long before the Nats were done this way. In fact, it was our success with running classes this way that lead to the Nats adopting it. You just need good frequency control. Later, we decided to allocate certain frequencies to each class and frequency control became easier.<DIV><BR class="khtml-block-placeholder"></DIV><DIV>Ron Van Putte</DIV><DIV><BR><DIV><DIV>On Jun 7, 2007, at 11:42 AM, J N Hiller wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"> <DIV class="Section1"><P class="MsoNormal"><SPAN class="EmailStyle18"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size:10.0pt;mso-bidi-font-size:12.0pt;font-family:Arial">Hi Ron.

Flight order on multiple flight lines was arranged to position or separate conflicting frequencies which was inconvenient at times, especially when mulligans disrupted the planned flight order. I guess I didn’t understand the NATs planning problem. As I remember frequency allocation first appeared when pattern and pylon events were flown simultaneously and it was a no brainier to extend frequency allocation to classes flown simultaneously on different flight lines. Can you fill me in on the problem?<O:P></O:P></SPAN></FONT></SPAN></P><P class="MsoNormal"><SPAN class="EmailStyle18"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size:10.0pt;mso-bidi-font-size:12.0pt;font-family:Arial">Thanks<O:P></O:P></SPAN></FONT></SPAN></P><P class="MsoNormal"><SPAN class="EmailStyle18"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size:10.0pt;mso-bidi-font-size:12.0pt;font-family:Arial">Jim Hiller<O:P></O:P></SPAN></FONT></SPAN></P><P class="MsoNormal"><SPAN class="EmailStyle18"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size:10.0pt;mso-bidi-font-size:12.0pt;font-family:Arial"> <O:P></O:P></SPAN></FONT></SPAN></P><P class="MsoNormal" style="margin-left:.5in"><FONT size="2" color="black" face="Tahoma"><SPAN style="font-size:10.0pt;font-family:Tahoma;color:black">-----Original Message-----<BR> <B><SPAN style="font-weight:bold">From:</SPAN></B> nsrca-discussion-bounces@lists.nsrca.org [<A href="mailto:nsrca-discussion-bounces@lists.nsrca.org">mailto:nsrca-discussion-bounces@lists.nsrca.org</A>]<B><SPAN style="font-weight: bold">On Behalf Of </SPAN></B>Ron Van Putte<BR> <B><SPAN style="font-weight:bold">Sent:</SPAN></B> Thursday, June 07, 2007 6:14 AM<BR> <B><SPAN style="font-weight:bold">To:</SPAN></B> NSRCA Mailing List<BR> <B><SPAN style="font-weight:bold">Subject:</SPAN></B> Re: [NSRCA-discussion] For Sale</SPAN></FONT></P><P class="MsoNormal" style="margin-left:.5in"><FONT size="3" face="Times New Roman"><SPAN style="font-size:12.0pt"> <O:P></O:P></SPAN></FONT></P><P class="MsoNormal" style="margin-left:.5in"><FONT size="3" color="black" face="Times New Roman"><SPAN style="font-size:12.0pt;color:black">I also remember a Nats meeting in which flying by class, instead of by frequency, was discussed.

Rick Allison designed the Olympian. Back in the early '90s I made the comment to him that I thought pattern planes would be better with fixed gear (and fat fuselages), and he told me in no uncertain terms that "Pattern planes would never fly right with fixed gear". It would "screw up the force arrangement". I thought he was going to burst a blood vessel.</SPAN></FONT><FONT color="black"><SPAN style="color:black;mso-color-alt:windowtext"><O:P></O:P></SPAN></FONT></P><P class="MsoNormal" style="margin-right:.5in;mso-margin-top-alt:auto;mso-margin-bottom-alt: auto;margin-left:1.0in"><FONT size="3" color="black" face="Times New Roman"><SPAN style="font-size:12.0pt;color:black">Never say never!! :-)</SPAN></FONT><FONT color="black"><SPAN style="color:black;mso-color-alt:windowtext"><O:P></O:P></SPAN></FONT></P><P class="MsoNormal" style="margin-right:.5in;mso-margin-top-alt:auto;mso-margin-bottom-alt: auto;margin-left:1.0in"><FONT size="3" color="black" face="Times New Roman"><SPAN style="font-size:12.0pt;color:black">Bob R.</SPAN></FONT><FONT color="black"><SPAN style="color:black;mso-color-alt:windowtext"><O:P></O:P></SPAN></FONT></P><P class="MsoNormal" style="margin-right:.5in;mso-margin-top-alt:auto;mso-margin-bottom-alt: auto;margin-left:1.0in"><FONT size="3" color="black" face="Times New Roman"><SPAN style="font-size:12.0pt;color:black"><BR> <BR> <B><I><SPAN style="font-weight:bold;font-style:italic">Ed Deaver <<A href="mailto:divesplat@yahoo.com">divesplat@yahoo.com</A>></SPAN></I></B> wrote:</SPAN></FONT><FONT color="black"><SPAN style="color:black;mso-color-alt: windowtext"><O:P></O:P></SPAN></FONT></P> <DIV style="border:none;border-left:solid #1010FF 1.5pt;padding:0in 0in 0in 4.0pt"><P class="MsoNormal" style="margin-right:1.5in;mso-margin-top-alt:auto; mso-margin-bottom-alt:auto;margin-left:79.5pt;border:none;mso-border-left-alt: solid #1010FF 1.5pt;padding:0in;mso-padding-alt:0in 0in 0in 4.0pt"><FONT size="3" color="black" face="Times New Roman"><SPAN style="font-size:12.0pt; color:black">Piorun Olympian Medal with fixed gear and cheek cowls added.</SPAN></FONT><FONT color="black"><SPAN style="color:black;mso-color-alt:windowtext"><O:P></O:P></SPAN></FONT></P> </DIV><P class="MsoNormal" style="margin-right:.5in;mso-margin-top-alt:auto;margin-left: 1.0in"><FONT size="3" color="black" face="Times New Roman"><SPAN style="font-size: 12.0pt;color:black">_______________________________________________</SPAN></FONT><FONT color="black"><SPAN style="color:black;mso-color-alt:windowtext"><O:P></O:P></SPAN></FONT></P><P class="MsoNormal" style="margin-right:.5in;mso-margin-top-alt:auto;margin-left: 1.0in"><FONT size="3" color="black" face="Times New Roman"><SPAN style="font-size: 12.0pt;color:black">NSRCA-discussion mailing list</SPAN></FONT><FONT color="black"><SPAN style="color:black;mso-color-alt:windowtext"><O:P></O:P></SPAN></FONT></P><P class="MsoNormal" style="margin-right:.5in;mso-margin-top-alt:auto;margin-left: 1.0in"><FONT size="3" color="black" face="Times New Roman"><SPAN style="font-size: 12.0pt;color:black"><A href="mailto:NSRCA-discussion@lists.nsrca.org">NSRCA-discussion@lists.nsrca.org</A></SPAN></FONT><FONT color="black"><SPAN style="color:black;mso-color-alt:windowtext"><O:P></O:P></SPAN></FONT></P><P class="MsoNormal" style="margin-right:.5in;mso-margin-top-alt:auto;margin-left: 1.0in"><FONT size="3" color="black" face="Times New Roman"><SPAN style="font-size: 12.0pt;color:black"><A href="http://lists.nsrca.org/mailman/listinfo/nsrca-discussion">http://lists.nsrca.org/mailman/listinfo/nsrca-discussion</A></SPAN></FONT><FONT color="black"><SPAN style="color:black;mso-color-alt:windowtext"><O:P></O:P></SPAN></FONT></P><P class="MsoNormal" style="margin-left:.5in"><FONT size="3" color="black" face="Times New Roman"><SPAN style="font-size:12.0pt;color:black"> </SPAN></FONT><FONT color="black"><SPAN style="color:black;mso-color-alt:windowtext"><O:P></O:P></SPAN></FONT></P> </DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_______________________________________________</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">NSRCA-discussion mailing list</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="mailto:NSRCA-discussion@lists.nsrca.org">NSRCA-discussion@lists.nsrca.org</A></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="http://lists.nsrca.org/mailman/listinfo/nsrca-discussion">http://lists.nsrca.org/mailman/listinfo/nsrca-discussion</A></DIV> </BLOCKQUOTE></DIV><BR></DIV></BODY></HTML>
