LEGO Technic Building Tip - Motorized Extendable Outriggers

The LEGO Technic 42043 Mercedes-Benz Arocs 3245 uses two brand new pieces to make a smaller and simpler outrigger system for trucks (Design IDs 18940 and 18942). In another post, I showed the manual outrigger stabilizers. This time, we will see how the outriggers can be extended with the power of a motor. 

You can see the outrigger system in the pictures above and below, composed of two identical units connected together. A layer of gears are laid on top of the outriggers. The two black gears run on the outriggers' gear racks. The light grey gears keep them in sync. The power comes through the axle with the red connector at the end. This can go straight to a motor, or more ideally to a 2 function switch or 4 function switch so that the motor can be utilized for other functions also.
