Jurgen "Boetty" Bottcher scratch-built this radio-controlled model of the Tirpitz 26 years ago. The scale is around 1:100 and after a quarter of a century, the model is still fully functional. The propulsion system uses three motors and ship’s machinery consists of smoke, sound, siren, lights and air compressor. The main guns use the air compressor for shooting water. Boetty can be contacted at jbs-heimkino@t-online.de and has his own site at www.jbs-heimkino.de.
