WP SHARK U-Boot Graupner 2172 This semi-scale model of a research submarine is mainly meant for the advanced modeller. The sub dives dynamically. Use of the recommended powerplant provides a speed of 2-3 m/sec. For this reason the submarine should be operated in clear water only or in a swimming pool etc. The running characteristics of the submerged vehicle are comparable with those of a model plane in flight. An inexperienced pilot should therefore
preferably operate the submarine at reduced speed. Well-trained submarine commander may consider the installation of a higher-powered
motor to increase the speed of the model still more. The plastic hull consists of two parts. Power is supplied by an electric motor SPEED 500, the output of which is transmitted to two contra-
rotating marine propellers via a gearbox. Quickbuild plan incl. R/C installation, building instructions in Dutch, English, French, German and Italian. Blown hull parts, rudder, flooding chamber, gaskets, valve trim flaps, hoses, Bowden cable, trim sheet and miscellaneous parts.
