9VAP, or 9VAP?  (I think a VAP).
 
89 was the last year I flew brand "F" - and I was flying the old 8 
channel 512 PCM, which was flawless.
 
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.
