Winch set up?

[frizzen]

Are you wanting proportional control, or just single speed?

If you're using servos you're converting, you can hack the board to use it as an esc. it'll often want to drift some and not have a wide deadband. It'll cost some solder, resistors, and time fiddling with finding neutral.

You can get 'winch controllers' from places like heyok, they won't drift but most run single speed. If it's on a switch, these are great.

If you want to control line speed, I would try to go with individual 10-20amp reversing esc, probably just the cheapest ones i could find. If it's on a stick or a pot, these are great.
