Hi. I devised my own sail winch system that uses a regular servo (one of the little junky ones that comes with my Futaba Attack SR) to activate two buttons that switch the polarity on a geared-down electric motor.
I plan on having the output shaft of the motor gearbox protruding from my watertight servo/battery box and attaching whatever pulleys I need to that, with some limit-switches to cut power when the winch has gone as far as it needs to.
The goal of this being (of course) to save myself 100 bucks, which is the approximate cost of a sail winch in New Brunswick, Canada.
Is there any reason why this is a bad idea? Has anybody tried it? As I said in my last post, I am new to this RC sailing stuff and I need ideas.
