The submarine motor which comes with this set is easily switched on and off by rotating the motor body and its rudder angle may be changed to enable running in circles. The boat's hull is made from the same durable plastic material as the submarine motor and may be finished with Tamiya Color paints. One R6/AA/UM3 battery provides about two hours of running time.
