LEGO release a nice kit for adding movement to our Technic constructions, the Power Function 8293 set.
But what happens if your vehicle is to big and weights so much that not even the XL motor can move it at a decent speed? Don’t despair. Here you have a LEGO sized V8 motor at your rescue!
This big engine is built using LEGO Pneumatic parts and although you don’t see it on the video works with an air compressor, which makes the pistons goes in and out, which in turns moves the connecting rod that transform the horizontal movement of pistons in a circular movement ready to be transferred to the wheels.
Have you build any model where XL motor wasn’t enough?
