The 3-speed crank-axle gearbox looks very much like half of the twin-motor gearbox; it even uses the same gears. Gear it for power or speed. A FA-130 motor is included.
Great for a high torque or high speed adjustable drive wheel or lifter arm. Get 2 for a two-wheel drive bot and cut the shaft for whatever side you need. Some assembly required.
