This is a remote control 4×4 rock crawler and it comes from previous bloggee Technic BOOM. If you’re a regular reader of this dilapidated corner of the ‘net you might now be expecting a tale of mass Elven destruction, corridor smushings, and even a trip to the ‘Elf Hospital‘.
However the clue is in the title with this post, as Technic BOOM’s creation is one of the slowest that we’ve ever encountered. This inevitably enraged the Elf that discovered it, unable as it was to inflict mayhem on its fellow Elves, but it also means that BOOM’s model is ridiculously capable off-road.
With gearing of 9:1, enormous non-LEGO RC tyres, remote control drive, steering, and differential lockers, Technic BOOM’s rock crawler can inch its way over almost anything. Very slowly.
There’s more to see of this superbly engineered machine on both Flickr and at the Eurobricks discussion forum, where you can also watch a video of it doing its thing on-location off-road.
