Discovered by one of our Elves on Eurobricks, this is newcomer McMarky’s rather good tracked excavator. Like all good Technic models, McMarky’s creation can operate just like the real deal, being able to drive and steer, rotate the superstructure, and dig – thanks to a three stage boom and excavating bucket – all of which are motorised.

Naturally such functionality necessitates a suite of motors, so how many do you think McMarky’s excavator has packed inside?

Nope. One.

Just a singular Power Functions L motor is able to drive all of the aforementioned functions, and – in many cases – multiple functions simultaneously. Which means not just no additional motors, but also no fancy programmable app-based remote control is required either, with the huge array of working functions instead controlled via a trio of red levers, each linked to the most complicated gearbox that we’ve ever seen.

It’s an outstanding example of mechanical engineering, and demonstrates that even if you don’t have the finances for a suite of motors, a third-party bluetooth battery, or access to a programmable app, immensely realistic motorised Technic creations are still within reach.

There’s more of McMarky’s seriously impressive uni-motor tracked excavator to see on Flickr and at the Eurobricks forum, where further images and a video of all those motorised functions in action can be found. Click the link above to be happy being single.
