Mclaren Clockwork Submarines

U60 has a 9 plate 0.2mm hull with a 0.5mm frame, the mega powerful drum motor drives her 50mm prop. The twin dive tanks fwd and aft are vented through the fin via flexible tubes in the motor section. The most novel aspect of this design is the removable motor which is accessed by the mid deck section. The fin and mid deck section is fixed with 12 M4 brass studs, brass dome nuts protect the threads with a double 1mm rubber gasket providing the water tight seal. The sprung loaded deck gun fires .177 lead pellets with cobweb shattering efficiency, for the cross threaded that's 4.5mm.
