RE: Outta my league here ....
There has been quite a lot of discussion in the IOM discussion groups about using the HS 5735 digital servo as an arm winch. Also if you want a traditional drum winch, look at from cheapest to most expensive: Hitec 725, Futaba 5801, Whirlwind (Atlas, Tensor, Olympic), or the RMG sailwinch 360, 260DL.
