Thanks guys. Indeed the sail winch IS a lump and required some butchery of the radio tray. Since I had got a spare 9001 servo knocking about so I changed my mind and Ive fitted that instead and will keep the winch for another boat...the Kyosho Fairwind maybe, or a marblehead, or maybe just pop it back in the drawer for another three years!
The servo with arm fits the radio tray a treat.
The TT Odyssey by the way is an 89 quid yacht, ABS hull, ally mast, usual stuff I am sure.
