- The Tugboat is driven by a rubber-band motor powered by the tension of the rubber connected with a bearing. The reduction gear transfers energy to the drive wheel and further to the asymmetrical wheel pair. The pendulum slows and evens the motion of the tugboat.
- The asymmetry of the wheel pair grants the model its unique way of moving, imitating a boat rocking on the waves, while the working pendulum creates a specific noise similar to one produced by the real-life diesel motor many boats are equipped with.
- The winding key on the drive wheel is blocked by a ratchet gear. There are two control levers, one of which stops the mechanism and the other launches it – stop and start lever correspondingly.
- Use two ropes with hooks to hook up and transport small freight – wheeled models or a paper boat. Your Tugboat will run from 1.5 to 3 meters depending on the type of surface.
