Rob, Thanks for your response.
I will try to answer your questions but I have only seen his set up once when he got it and once to sail it.
I believe he has something like the Kyosho Sea Dolphin with the Futaba Attack 2 channel seen here (

The radio is definitely a low end unit.
I never thought about just upgrading to a strong servo and still using the arm. That is how like I know about RC sailing.
So would you say a winch servo is out? I thought it sounded kind of neat when I found out that they were available.
