This small assembly will provide a solid method to gear the drive axle up or down.
The output (wheel) can be place on either side of the motor, and the motor can be inverted, depending on other building constraints.
The L-shaped beam is required to keep the gears close together, so they will not slip, or skip teeth.
This motor shaft will make 1 rotation, in the same time the output shaft makes 1
Gears used: 16 tooth on motor, 16 tooth on output
Gear Ratio: 1:1
Power: Same as motor
