Our spiral 45mm drum fits the new RMG G1 winch and it is made by RMG Sailwinch under Sailboat RC drawings. It is used in all our sailboats from around the middle of 2022. until today. This drum proved excellent in our design for IOM sailboats and other RC sailing classes. It has the outside spring in a loop that keeps the tension. Our drum (45 mm) is one of the best drum options you can use for IOM yachts as it provides excellent performance, durability and light mass! 103 Return Spring and 104 Ring SS included with the Drum as photos show. JUNE 2024 UPDATE: ITEM OPENED ONLY SO THAT IT CAN BE ORDERED AS PART OF VISS OR K2 IOM SAILBOATS, DELAYS EXPECTED FOR SPARE PART SALES ! If you need a winch, you can find it here: RMG winch
