Picked up one of these little gems from Amazon
This one is listed as the Goolsky Winch Controller but you'll find it under many names.
It's actually a small Electronic Speed Controller.
There were some modifications I had to make to get it to work with my Winch .
First because this is an ESC and it provides a BEC I needed to cut or remove the center RED wire from the receiver plug. Then I needed to swap the two red plugs around. In my case, the wire from the winch had a male plug and the cable I needed to connect it to also had a male. Also the wire from the controller going to the battery was a female (so you can plug it into a small 2s) but I needed it to be a male so I could plug it into the Y splitter coming off the 3rd channel. One side of the Y would take the Servo plug, the other one would supply the power to the winch.
