I'm using a 4 channel receiver in my RC crawler. I have channel 4 working fine via a switch for my lights, but ordered this to hopefully setup the winch.Sadly, after finally figuring out which side of the red connectors (the male one) controlled the esc power supply, I hooked it up to the car's esc outward power wires and it powered it up with the external switch (on a wire). There's no suggestion as to what the switch on the eac does.I've connected the winch up to the other red connector (female one), however it powers the winch one way, but does nothing from the transmitter switch to turn it off or change direction.This also gets hot quite quickly, which makes no sense.Unfortunately, it doesn't appear to be fit for purpose and I can't therefore recommend it.
