Maybe you have heard of or experienced first hand what people are calling winch drift or winch creep...
Are you running a winch that you made by modifying a servo? A lot of people are finding that the winch tends to drift over time. They might be driving along and suddenly realize that some length of winch cable has been unspooled and if you are really unlucky, it ends up wrapped around your axle!
HeyOK has built a replacement for the electronics inside a servo that won't drift on you. Remove the old servo controller circuit by desoldering it from the motor and pot and then solder this new circuit to the motor. An added benefit is that when the winch is stopped, the circuit provides an electric "Brake" to help hold the winch unlike the stock servo circuit that doesn't provide any electric braking.
Also works with the 3racing winch. Cut off the red JST connector from the 3racing winch and splice in the two wires on this servo controller in place of the old controller.
Designed to work with a radio/transmitter that has a 3-position third (or other) channel.
