Notes
- The discontinued Graupner Regatta is a specialized, high-power sail winch servo, embodying the precision engineering that competitive RC sailors demand. It is designed to be the powerful heart of a racing yacht's sail control system. Unlike flight servos, a sail winch is designed for high-torque, multi-rotation travel to handle the long lines (sheets) that control the sails. On the upwind leg of a race, with the wind building, the Regatta has the immense power to sheet in the mainsail and jib tightly, creating a perfect airfoil against the force of the wind. Its precision allows for the fine, millimeter-level adjustments needed to trim the sails for maximum speed.
- The identity of the Regatta is its purpose-built design for the unique demands of RC sailing. It is built to withstand the wet environment of a boat's hull and features a robust, high-torque gear train that can handle the constant, heavy loads of sheeting without fading or failing. It provides the smooth, proportional control over several turns of its drum that is necessary to let the sails out on a downwind run and then crank them back in for a tack. It is a true instrument for the competitive skipper.
- For roboticists, the Graupner Regatta's high-torque, multi-turn capability is invaluable. It is a perfect actuator for a large, drum-based winding mechanism, a powerful positioning system for a large sensor array, or any application that requires precise control of a long-travel linear motion via a cable and pulley system. It is a unique and powerful tool for custom mechatronics.
