I fly by the seat of my pants, stealing ideas from wherever I find them, and haven't the skills, tools, or money to "machine" intricate control systems for my boats.
Keeping all that in mind, do you have some idea of how you're going to control that rig?
On Constellation I wanted the braces out at the end of the yards as on the real ship - but different length yards mean changing vector geometry resulting in the winch set up I made, based on stolen ideas, and that have yet to be tested in combat. It works in other large models, so I confident it it's operation for me - but it relies on expensive winch servos which I have already zapped once by connecting the battery with the poles wrong and cost as much as another winch to have them repaired.
Pride is getting a fairly typical control system for a schooner, but with enhancements to handle running backstays and forestays along with three overlapping sails and squares.
Macedonian I plan a cordless drill motor driven system controlled by micoswitches and cheap little servos. The working braces will be set maybe 6 inches out on the yard and be clear monfiliment while the "scale" braces will run free and just be for looks - eliminating all the fancy geometry and expensive winch servos.
The fore mast should be separately controlled from the main and other after masts to allow you to back wind the fore sails and box the head when tacking. The heads'l that likely overlap a great deal on your prototype vessel can have the clews and foot set higher to minimize, and even eliminate the overlap and make it easier to sheet them without snagging.
Give some thought to being able to shorten sail - not necessarily remotely, but manually at the ponds edge. The easier it is to remove and place t'gallants' royals, heads'ls, brail up courses, and even reef tops'l - the more enjoyable sailing the model will be in almost any conditions. The smoother things operate, the more you'll want to sail, and the more satisfied you'll be with your efforts. If it's a pain to set up and operate, and she's always on her side in even a moderate breeze, the more sailing her will become a chore you'll try to avoid and she just collect dust or wind up on ebay.
