Guys got problem controlling your 3racing winch with a 2pos 3rd channel switch? If yes read on
What I did was I just soldered a diode in series with the winch motor either wire will work. Basically the diode prevents back flow of the current which essentially turn one of the direction OFF and the other ON. The diode has a polarity but since the winch will spool back at the end of the winch cable length so polarity doesn't matter you can solder it in series in any direction. Spool direction is just a matter of personal preference or if you prefer the cables spool in under real. You'll need to manually pull the hook to release more cable doh.
Now im not good in electronics I dont even know what are the specs of the diode I used but basically it has a max reverse voltage of 12V which is more than enough since I only run on 6V (BEC supplied) power. Its as big as 1/4 watt resistor. However I notice a slight power loss maybe because my diode measured some ON resistance (if that is what it is called) that probably drop the actual winch motor input voltage or maybe just because of the extra load on my light system. If you or anyone can recommend a better diode specs, Im be very much thank full. BTW although I have not encountered any problem so far do this at your own risk.
