Here is a basic but strong servo winch for mini crawlers. I threaded the line from the back of aTRX4m where i mounted the winch and out through a hole i made in the imitation winch already fitted to the chassis.
You'll need a 360 micro servo which are available from many places, you can even convert them yourself from YouTube videos.
