- Driving and steering
- Turret rotation
- Vertical cannon alignment
- Firing and automatic loading of 11 rounds
These functions are achieved based on four motors allowing for minimum size of the MOC. It is achieved by combining the gun motor with a free wheel that allows for both, firing and vertical gun allignment. The selection of the function is achieved through the rotation direction of the motor.
The shooting mechanism is based on the yellow rubber bands that are installed like this. Instead steel springs can be used that are installed like this.
See the constuction hints for the turret here. The structure of the tank is rigid thanks to the full integration of the battery box. Battery replacement is still easy, provided you do not install the covers. By removing a few elements the access to the batterys is simple for the bottom side and the top side. The battery box can be switched on and off through the manhole in the tank.
