Graupner bulkhead drive II 2335

Graupner 2335 bulkhead drive II Description
A Schottel drive, developed by the Schottel company, is a modern and particularly powerful drive version especially for working ships which must have very high manoeuvrability, such as harbour tugs, ferries and special ships. In contrast to conventional ship drives with separate shaft and rudder systems, both control groups are combined in the Schottel drive. The ship's propeller, which is mounted under the ship's bottom in a performance-enhancing cork nozzle, can be swivelled to the side and the water flow produced is thus used directly as a rudder. The Schottel drive II corresponds to the original concept in its mode of operation. In conjunction with the powerful SPEED 900 BB Torque electric motor (Order No. 6373), the integrated gearbox with a 3:1 ratio and the special 65 mm propeller, a high drive power is achieved, making the drive suitable for use in larger and heavier models. It is sturdily made of plastic. For direct control, a powerful servo (e.g. C 4821, Order No. 3896) is inserted into a special holder. The swivel range of the propeller is approx. 180° with a servo movement ratio of 2:1, depending on the servo. The swivelling range is not mechanically limited. The servo carrier can be attached to the side of the shaft in various positions depending on the installation conditions.
