<DIV>9VAP, or 9VAP? (I think a VAP).</DIV>
<DIV> </DIV>
<DIV>89 was the last year I flew brand "F" - and I was flying the old 8 channel 512 PCM, which was flawless.</DIV>
<DIV> </DIV>
<DIV>And while I don't recall the exact number of crashes (1 is believable), I know of one plane which did crash and that TX had gotten absolutely soaked earlier that day or the prior day in a rainstorm during a practice flight - I saw easily 1-2 oz of water dumped out of the TX at the end of the practice flight.</DIV>

The problem was with the 9VAL system, <BR>> specially their new 1024 receivers. Interesting though there was only <BR>> one crash and everyone else regained control as the plane got low <BR>> enough. As I mentioned I loaned them all six of my 8 channel PCM 512 <BR>> receivers which were on 6 meters. Steve Helms brought a team of 6 folks <BR>> in and did extensive testing twice. What they found was two areas at <BR>> Vista field where high reflection from buried metal and was quite <BR>&
gt; noticeable in the receivers. They deduced that the rejection <BR>> sensitivity was not only two small, but the logic for rejection took too <BR>> long to determine it was OK after the interference left. Helms flew his <BR>> plane all around for days at Vista and could not repeat the situation, <BR>> but it was in September and much cooler than during the Nat's. They <BR>> recalled all of the 9VAL receivers and repaired them for nothing. <BR>> Somewhere I still have a T-shirt that says "I survived the 1989 Nat's <BR>> Lockout"". <BR>> <BR>> Bill <BR>> <BR>> <BR>> <BR>> Dennis Cone <BR>> <BR>> <BR>> <BR>> _______________________________________________ <BR>> NSRCA-discussion mailing list <BR>> NSRCA-discussion@lists.nsrca.org <BR>> http://lists.nsrca.org/mailman/listinfo/nsrca-discussion </BLOCKQUOTE></body></html>
