Mechanical ‘Mog

LEGO’s official Technic 8110 Mercedes-Benz Unimog U400 set earned a stellar 9/10 rating here at The Lego Car Blog when it was reviewed way back in 2011. Fantastic functional realism, excellent use of motorisation, and an on-board pneumatic compressor make 8110 one of the finest sets we’ve ever reviewed. However, whilst expensive then, 8110 is ludicrously pricey now.

Cue previous bloggee thirdwigg, who has created his own superbly engineered Technic Unimog U400, only all-mechanical.

The loss of Power Functions components hasn’t reduced the functional realism though, with thirdwigg’s U400 equipped with all-wheel suspension, four-wheel-drive connected to an inline-4 engine under a tipping cab, working steering, a front and rear PTO, three-way tipping bed, and a pneumatic take-off too.

It’s a brilliantly simplified (but in no way simple) take on the original 8110 set, and one that you can build for yourself, as thirdwigg has released instructions for his model alongside the excellent imagery you see here.

If you missed out on the official LEGO Technic 8110 Mercedes-Benz Unimog U400 set a decade ago, and baulk at the price of them today, check out thirdwigg’s wonderfully engineered 4/5ths version at his ‘U400’ album via the link above, plus you can watch all of the model’s features in action via the video below.

Medium ‘Mog Magnificence

LEGO’s 8110 Technic Mercedes-Benz Unimog set earned a stellar 9/10 review here at The Lego Car Blog. With working steering, suspension, engine, all-wheel-drive with portal axles, Power Functions motors, and pneumatics, it’s one of the finest sets in Technic history. However, as is often the way, you guys can do even better.

This is MajklSpajkl’s Mercedes-Benz Unimog U400, and it’s around half the size of the official 8110 set. And yet, even more incredible functions are squeezed inside.

Like the official LEGO set, MajkleSpajkl’s Unimog features all-wheel-drive with portal axles and three differentials, in this case linked to both a four-cylinder piston engine and an XL Motor that provides the model with drive. A Servo controls the steering, simultaneously turning the steering wheel, whilst a Medium Motor drives both the front and rear power take-offs.

A further L Motor powers a pneumatic compressor for the attachment functions, and can also tilt the rear bed (if fitted) in three directions. We write ‘if fitted’, because as per the real Unimog, MajklSpajkl’s creation can be equipped with a variety of attachments, with a tilting bed, front winch, rear-mounted crane, double-auger gritter, and snow plough variously pictured here.

Both the crane and snow plough movements are controlled via pneumatics, pressurised via the on-board compressor, whilst the PTOs provide motorised drive to the crane’s rotating turntable and outriggers, and the gritter’s rotating dispenser respectively. Not only that, but the cab doors open, the cab itself can tilt, and there’s a front mounted winch option, again motorised via a PTO.

All the above are controlled via a BuWizz Bluetooth battery, allowing the U400 to be operated via mobile phone, and there’s lots more to see of MajklSpajkl’s incredible (and beautifully presented) creation at the Eurobricks forum.
