TAMIYA Underwater gear box set

It is mounted on a mini-submersible motor (high-speed type), and it is an assembled type gearbox that can extract power to the side.
I install a pinion gear instead of a screw and use a crown gear to reduce the rotation of the motor. A hex shaft for powering is available in 3 different hole positions and is also equipped with a circular crank plate and removable wheels.
You can also enjoy the work of amphibious cars.
In addition, you can attach the wheel of mini 4 wheel drive to the hexagonal shaft. Includes a plate for screwing foam polystyrene (sold separately) used as a float.
Total length = 109 mm. Maximum diameter = 23 mm (mini-submersible motor). One AAA battery (sold separately).
