Mclaren Clockwork Submarines

This boats so cool to sail,with the two tanks, the buoyancy can be set to a minute degree giving total control over the dive.I can actually set it to periscope depth.By charging the air tank with a bike pump, it can be sent to the bottom for up to two hours and then will blow ballast and surface. The motors a tad powerful,but not as fast as some of my boats. However It will surface run pretty quick. All in all a total bazzer of a sludgemarine.
