#GRP2358 voith-schneider propeller UNIT  

True-scale propeller driven unit for powering and controlling model boats. The Voith-Schneider propeller unit VSP for model boats was developed with all the basic functions emulating those of the original. In the Voith-Schneider system the propeller generates both thrust and steering forces by altering the angle of the propeller blades.
Changes in speed are produced by altering the pitch angle of the propeller blades; motor speed remains constant. Thrust vectoring is used to alter the direction of running, with infinite variation available through 360º without any change in the direction of motor rotation. For this reason only a simple motor switch or a forward- only speed controller is required for the motor. The VSP is designed as a robust slow-running unit (the SPEED 500 E 12 V motor supplied is fitted with an appropriate reduction gearbox). In an effort to generate as little noise as possible, the reduction gearbox is based on a toothed belt reducer. The system is straightforward to install in the model boat: the mounting ring (supplied) is glued in the hull, and the VSP is simply screwed to the ring. The main shaft is supported in two rubber-sealed ballraces, making the VSP unit virtually watertight. All other heavily stressed parts are made of metal or high-quality bearing plastics, and the unit can be expected to have a long useful life if maintained properly. The propeller blades can be replaced easily if they should become damaged. Two servos are required to control the system.

#GRP1761 schottel drive unit

The Schottel drive unit, developed by the Schottel company, is a typical power unit installed on many types of working vessel such as tugs, ferries and buoy layers. The power of the drive motor is transmitted to the propeller, which is able to swivel. This arrangement alters the angle of thrust of the power unit directly, i.e. the flow is not deflected by a rudder, and this makes the Schottel drive unit a highly efficient design. The Graupner Schottel drive unit I emulates the functions and construction of the full-size system: the swivel range is 2 x 90º if a 2 x 45º servo is used. The drive unit is designed for the use of SPEED 500 to SPEED 600 motors with a maximum output power of 50 Watts. The shafts are made of V2A stainless steel, and run in ball races in the more heavily stressed areas; the other bearings take the form of high-quality metal bushes. The Kort nozzle of the drive unit is attached to the motor by means of a locking device, making it a simple job to remove the propeller
