well 2 key issues I can see first hand. One is around furling or unfurling the Gen as you can't really sail your RC boat with that sail up. A all or nothing switch could do that with a similar system then on full size boat but with a close sheet circuit and an end point to stop the furling or unforling. Then it's the question of controlling that sail. there you can look at boats equipped with a genoa but you typically need 2 winch for that alone.. this combined with the unforling system and the normal sheeting systems for your jib and main and you end up with a rather complicated and heavy solution.

Not impossible but you'd want to have a pretty big boat 1.6 or 2m long to justify the weight and the room needed inside the hull.

not the answer you were looking for but there you go... unless someone knows or has seen an innovative way !!!

Good luck.
