HI Mark
That should be one hell of a model……I would seriously talk to the yacht guys, they will put you straight about sail winches. As to the rest of the gear, cost is the only proviso, I started with Radio link, cheep and cheerful, no problems with it, replaced with Crimbo pressy of a Futaba T6 with extra receivers, first sailing end of December worked very well.
Use your flight tranny, on 2.4 there is no difference, not like 27, 35 or 40mhz.
