[NSRCA-discussion] GWS Servo/Transmitter Tester/Tachometer

[Ron Van Putte]

What's needed is for one of you "electronic gurus" to tell us which  
pins on the "new" Futaba (square) trainer cord plug should connect to  
which pins on a universal servo connector so we can use the GWS MT-1  
Multi Tester to look at the pulse widths of nine channels coming out  
of the transmitter.  Then we can make our own transmitter signal  
cord.  :-)
