Scorpion King

Lego Technic RC Ponsse Scorpion King Forester

The Scorpion King may be a truly awful movie spun off from a merely not very good one (although this TLCB Writer will watch it at every opportunity for one simple reason), but it managed to spawn both an even more pointless sequel and give name to an obscure Finnish forest harvester range.

OK, we’re not really sure if the marketing department at Ponsse actually named their eight-wheel harvester line after a terrible Dwayne Johnson film, but they do share the same name.

This goliath of a model is a fully-functioning Technic recreation of that Finnish forester, and it’s a work of engineering genius. Powered by eleven motors, marthart‘s Ponsse Scorpion King can drive, steer via linear-actuator driven central articulation, raise, extend and turn the harvesting arm, and do whatever-it-is that the thing on the end does to harvest trees, all via remote control.

There’s also an on-board compressor for the pneumatic system, an inline 6-cylinder engine, working suspension, and a detailed tilting cabin too.

There are more images available to view at marthart’s Ponsse Scorpion King album on Brickshelf via the link above, and here’s another bonus pic because something good had to come from that dismal movie…

Slowly Smushing

Lego Technic RC Dakar Truck

It’s been a while since the last episode of Elf-on-Elf violence (even Elven behaviour during this year’s FIFA World Cup even proved uneventful, unlike the last one), however today we’re back to earth with a bump, thanks to this (admittedly incredible) fully remote controlled Dakar rally truck by Lucio Switch.

Driven by four XL motors with a Servo for steering, plus live-axle suspension, pneumatically controlled differential locks powered by an on-board compressor, LED lights and SBrick bluetooth control, Lucio’s Dakar truck is an engineering masterpiece. All of that lot makes it supremely capable off-road, where it can slowly climb over almost anything. Elves included.

Lego Technic RC Dakar Truck

As is the way with heavy remote control Technic models Lucio’s truck is pretty slow, and certainly no match for a fleeing Elf. But if a trap of sticky-side-up parcel tape has been laid by one of the little scumbags, the truck’s slow speed (but massive weight) are – if anything – advantageous to a good smushing.

So cunning was this inventive new use for sticky tape that we almost respect the Elf that did it. Almost. Because not only did we have to collect some thoroughly smushed Elves, they had to be pulled off the parcel tape too, which was not appreciated by them one bit.

We’re now going to look into a more secure stationary storage solution whilst you can check out all of the superb images of Lucio’s amazing creation on Flickr, plus you can join the discussion and watch the truck in action via the Eurobricks forum.

Elven Eviction

Lego Caterpillar D11T Bulldozer RC

All was quite in The Lego Car Blog Towers this morning. The Elves were asleep in their cage room and we were quietly watching the Monaco Grand Prix qualifying, er… we mean working studiously in the office.

And then came the sound of several soft thuds, kind of like a series of bean-bags falling off a table, followed by great Elven rage. Sigh.

A wander down to the cage room revealed the cause, where an enterprising Elf had returned early in the morning whilst its colleagues were still asleep, and promptly driven a remote control bulldozer through the Elves’ cages – much to its own amusement – pushing them out and onto the floor below. Cue the Elven rage.

Unable to escape by riding atop the ‘dozer due to its limited speed, the unhappily awoken Elves had caught their attacker and were trying to feed him into the VHS machine. Mr. Airhorn was deployed to restore calm (which definitely awoke any Elves fortunate enough to avoid the original incident) and we’ve now taken control of the offending vehicle.

Lego Caterpillar D11T Bulldozer RC

And what a vehicle! Based on the Caterpillar D11t bulldozer, Piotr K‘s creation is a superb example of how to utilise both Power Functions and pneumatics.

Two Power Functions L Motors drive the tracks, which are suspended by a pendular equaliser bar, whilst three M Motors power the pneumatic systems, with one driving an on-board compressor (with an auto shut-off) and the other two activating the pneumatic valves. This gives Piotr’s model a continual supply of compressed air to power the huge front blade and the rear-mounted ripper which can be operated remotely via LEGO’s IR system.

It’s very neatly engineered set-up and one that works – as the Elves found out – really effectively. You can see more images and read about the build on MOCpages via the link above, plus you watch the model in action via the YouTube video below.

The Other Challenger

Lego Challenger MT-865 Tractor

The Dodge Challenger has appeared here numerous times over the years. This isn’t that Challenger. Nope, this one is made by Caterpillar, and it comes from a series of tractors that were the first to be specifically designed to run on tracks.

This brilliant Model Team recreation of the latest Challenger MT865C comes from the appropriately-named Eric Trax, who has done a simply astonishing job replicating the Caterpillar in Lego form. And Eric’s creation is far from a static model…

Lego Challenger MT-865 Tractor

Inside the beautifully constructed exterior are a wealth of electronic and pneumatic components, allowing Eric’s Challenger to drive, skid-steer, and power both an on-board compressor and power-take-off.

Hooked up to the back of the MT865 is a Kinze 1050 grain trailer, complete with its own Medium motor and pneumatics to control the unloading auger.

Lego Challenger MT-865 RC

All of these functions can be controlled remotely via bluetooth, thanks to the third-party SBrick concealed within the build. This enables the models to be controlled by a phone or, as Eric has done, by a Playstation 4 controller!

There’s much more to see of this amazing Caterpillar Challenger MT865C tractor and Kinze 1050 grain trailer at both Brickshelf and the Eurobricks forum – click the link to see all of the images and to read complete build details.

Mighty Mercedes

Lego Technic Mercedes-Benz Zetros Truck RC

This stunning looking Mercedes-Benz Zetros 6×6 crane truck is the work of newcomer JRX, and it’s might just be the most technology and feature packed model of the year so far.

Underneath the realistic exterior are fourteen Power Functions motors, fifteen pneumatic cylinders and ten pairs of LED lights. Oh, and a third-party BuWizz brick to provide the power required and control the working functions. Now concentrate, here comes the science part…

Lego Technic Mercedes Zetros 6x6

All six wheels of JRX’s Zetros are independently suspended and powered by four LEGO Buggy Motors, with the three differential locks activated by a Servo motor and four pneumatic cylinders. These pneumatics are powered by an on-board compressor consisting of a Large motor and four pneumatic pumps, which also drive the crane extension and boom lift via a further five pneumatic cylinders.

A Medium motor and a further three Servo motors power the crane winch, rotation and elevation, whilst another Servo, Medium motor and two more pneumatic cylinders drive the outriggers. One final Medium motor powers the front winch and ten pairs of LEDs light the headlights, tail-lights, floodlights, warning lights and flashing turn signals.

JRX’s Mercedes-Benz Zetros has more squeezed inside it than your Mom’s corset, and just like your Mom there’s a video of it action available to view online. You can watch the Zeros is action via the video below, and you can see all of the photos and read further build information at both JRX’s Flickr photostream and via the Eurobricks discussion forum.

Trucavator

Lego Technic Tatra Truck Excavator

We don’t see this type of vehicle in TLCB’s home nation, and we’re not really sure why. A hybrid of truck and excavator it seems like quite a useful design, being fast enough to drive on roads without annoying everyone and diggery enough to do some digging when it reaches its destination.

This pneumatically-powered Technic version is based on a Tatra 815 with a UDS excavator mounted to the rear. It’s been built by newcomer Ivan MOC and it features working steering, a V4 piston engine, suspension on all axles, pneumatic stabilisers and boom elevation, manual boom extension and 360° excavator rotation.

There’s more of Ivan’s build to see at Eurobricks and Flickr – click the links if you dig it.

Candy Crush

Lego Technic Volvo FMX 4x4 Crawler RC

It’s been a slow (read ‘hungry’) week for The Lego Car Blog Elves. However, with their empty stomachs ‘motivating’ them it was only a matter of time before we’d have a creation to share with you.

The hungry Elf responsible for today’s find was duly awarded a meal token and Smartie, upon which something remarkable happened… the Elf ate about half of its Smartie, and it then proceeded to break the rest into pieces. Were we about to witness the first ever moment of Elven compassion and sharing? Were we balls.

The aforementioned Elf scattered the Smartie pieces opposite a curtain in the office and then scurried off. Soon several of its colleagues had sniffed out the unguarded confectionary and landed on the abandoned loot like seagulls on an open bin.

But unguarded the confectionary wasn’t, and the curtains suddenly parted as a huge white truck powered through them. The nearest Elf had just enough time to point and scream before being squashed forcefully into the office carpet, before its scavenging colleagues met the same fate.

A jubilant Elf then re-emerged, scooped up the Smartie remnants, and ran off cackling madly. Sigh. We thought they were getting bored of this.

Still, kudos the Elf in question, which had deployed some remarkable inventiveness to overcome its find’s lack of speed – which normally would have left it unable meet out any smushings.

The vehicular weapon, whilst slow, is a mighty impressive bit of kit though. Based on a Volvo FMX truck, the build features five Power Functions motors that power the four-wheel-drive system, generate air pressure for pneumatically locking differentials, and drive the centrally-pivoted steering, whilst pendular suspension with simply ludicrous articulation and oversize tyres from the 42054 Claas Xerion tractor set take care of truck’s impressive rock-crawling ability.

The build is the work of TLCB debutant dgustafsson1317 and there’s an enormous gallery of high quality images available to view on Flickr. Click the link above to see all of the Volvo FMX Crawler photos, whilst we scrape some very flat Elves out of the office carpet.

Pneumatic Crane Truck – Picture Special

Lego Technic Pneumatic Crane Truck

After a series of small creations we’re back with something big. Really big. Measuring almost a meter long, weighing over 8KGs, and constructed from around 8,000 LEGO pieces, Lucio Switch’s astonishing remote control and pneumatically-powered crane truck is one of the most complex creations that this site has published.

With seventeen Power Functions motors, eighteen pneumatic pumps / cylinders, and six switches, Lucio’s truck takes Technic construction to the limit of what is possible with Danish plastic. Four XL motors drive the rear wheels which are suspended on live axles, whilst the two front axles are steered by twin Servo motors and are suspended independently (which makes for no less than twenty-four shock absorbers in all!).

Lego Technic Remote Control Truck

Underneath the fully suspended and tilting cab (with a working steering wheel, suspended seats and an opening engine cover) is a working V8 piston engine, with twin LiPo batteries that power the motors and six sets of LED lights hidden within the chassis.

Nine M and two L motors then drive everything from the front and rear stabilisers, crane rotation, winch, and the pneumatic pumps which provide air pressure for the three-stage crane elevation and extension mechanism, all of which are controlled via four IR receivers through an SBrick bluetooth device.

Lego Technic Pneumatic RC Crane

Fortunately for us here in TLCB office that lot is much too complicated for our Elves to figure out, so Lucio’s incredible truck was unable to cause carnage and mayhem. It is however absolutely worth checking out, either at Lucio’s Flickr photostream or via the Eurobricks discussion forum, plus you can watch the truck in action via the video below. Prepare to be amazed!…

Two Technic Tractors Tuesday

Lego Technic Case 620 HD Tractor

Today’s blog post is brought to you by the letter ‘T’. Plus the Elves are learning about alliteration, which means that we have not one but two Technic tractors to show you.

They’re both remote control too, which also meant that we had something of an Elven showdown in the corridor this morning. Unable to squash any of their colleagues due to their finds herculean slowness, each Elf decided that the next best route to carnage was to turn their respective machines on one another. Cue the slowest vehicular joust in history, at the end of which the tractors calmly bumped into one another and the Elves at the controls left in disgust.

Well they may not be impressed, but we are, as each build is a masterclass in Technic engineering. Above is newcomer Brick_Sticker’s enormous Case 620 HD, driven by an XL motor and featuring an unusual (but very clever) pneumatic articulated steering mechanism, with an on-board compressor powered by a Medium motor providing the air pressure. Another Medium motor drives a power-take-off, and there are four pneumatic lines where tools could be attached.

It’s a spectacular machine and well worth your click – you can check out all the images and details via both Eurobricks and Brickshelf.

The Case’s gladiatorial opponent in the corridor joust comes from previous bloggee Damian Plesniak, and if anything it’s even slower. Driven by twin Medium motors, Damian’s tracked mini loader features skid-steering, plus a tilting and raising bucket powered by a third Medium motor and an XL.

It works a treat too, and you can see all of the (brilliantly taken) images on Flickr here, plus you can watch a video of the loader in action by visiting the Eurobricks discussion forum.

Big Forker

Lego Valmet TD 28-12 Forklift Truck

This blue behemoth is a Valmet TD 28-12 heavy-duty forklift, and it comes from probably the biggest company you’ve never heard of. Trading for over 200 years, Valmet are a Finnish manufacturer of, well… pretty much anything. Trains, trams, clocks, weaponry, aircraft, paper mills, cars, sauna thermometers, and – as here – tractors, are just some of the various products that the company has produced at one time or another. This huge forklift comes from Flickr’s Havoc, and it’s a fully operational engineering marvel. Forgoing the usual Power Functions motors, Havoc’s creation utilises pneumatics to power the forklift tilt, elevation and even variable fork-span. There are also working LED lights and Hand-of-God steering, and there’s more to see of this impressive machine on Flickr via the link above.

Big Yella

Lego Marathon LeTourneau L-1200 LeTro-Loader

This absolutely enormous contraption is a fully working 1:28 scale Lego replica of a Marathon LeTourneau L-1200 LeTro-Loader. Built by Beat Felber of Flickr this amazing creation all the functions of the real LeTourneau, a machine built to load 170-ton mining trucks with just a few scoops of its 22-cubic-yard bucket.

Beat’s Lego recreation of the L-1200 includes that huge bucket, controlled by two four-cylinder pneumatic pumps each powered by a Power Functions L motor and a Servo-actuated valve. Two more motors drive all four wheels via in-wheel planetary gear reduction, and the articulated steering is taken care of by a fifth electric motor, all of which is controlled remotely via three Power Functions receivers.

All in it’s an incredible feat of engineering and there’s more to see at Beat’s photostream – check it out via the link above if you did this build as much as we do.

Swirly

Lego Liebherr LH60 Timber

Splosh. [Elven screaming]. Splosh… Hmm… that doesn’t sound good. One weary walk down the corridor here at TLCB Towers later and the source of the disturbance was found. It’s been a while since an Elf brought back a remote control find to wreak havoc, but today old habits were resumed and havoc was indeed being wreaked.

This culprit was at the controls of this, gkurkowski of Brickshelf’s enormous fully functioning Leinherr LH60 timber grab. Despite featuring a beautifully engineered remote control all-wheel drive and steering system, the Liebherr was much too slow to run down and squash any Elves. Luckily for the pilot however, gkurkowski’s LH60 model also includes a remotely controlled rotating superstructure, two-peice pneumatic boom extension and a working grab, and it’s these features it choose to deploy.

Held aloft by its ears, an Elf was being repeatedly dunked in a toilet, in a manner similar to that used by public school bullies. Funny as this may have been, the Elves are not allowed in the TLCB Executive Washroom and Sauna so we had to put a stop to it. The very glum-looking victim is now sitting atop a radiator to dry out, whilst the victor has escaped with a yellow Smartie, and we’re left to have a go with the Liebherr ourselves.

Whilst we do that (for research) you can see loads more of the build, including some interesting work-in-progress shots, on Brickshelf – grab a look via the link above.

Pagani Huayra – Picture Special

Lego Technic Pagani Huayra Sariel

It’s time for something special. Really special. Poland’s Paul Kmiec, better known as Sariel, has been wowing the online Lego community for years. He’s a published Lego author and a veteran of this site, with a huge range of diverse Technic machinery published here over the years. His latest creation, in construction for months, reached TLCB yesterday, and we may only be a few weeks in but 2017 will have to be a pretty incredible year to beat it. This is Sariel’s fully remote controlled Technic Pagani Huayra…

Lego Technic Pagani Huayra Sariel

Built in 1:8 scale Sariel’s Huayra is a perfect Technic replica of the ultra-rare Italian hypercar. The bodywork, constructed from LEGO’s Technic panels, flex tubing and lift-arms, is a work of art, but it’s what’s underneath it that is truly remarkable.

Lego Technic Pagani Huayra Sariel

A remote control drive train, controlled by a third-party SBrick bluetooth module, powers the Huayra, with a remotely operable two-speed gearbox and fully independent adjustable suspension included too. There are opening doors, and functioning turn signals, reversing and brake lights – all engaged automatically when the Huayra turns, reverses or decelerates.

Lego Technic Pagani Huayra Sariel

Yes, decelerates – because Sariel’s Pagani features remotely operated working pneumatic brakes and the Huayra’s trick active aerodynamics, including the front and rear spoilers deployed on each side when cornering and the rear-mounted airbrake used during heavy deceleration.

The whole set-up is a delight to watch and you can do so via the beautifully shot video below, plus you can see the full gallery of exquisite imagery via Sariel’s photostream – click here to view one of the finest Technic Supercars ever built.

Whatta MAN…

Lego MAN TGX Truck

…whatta man, whatta man, whatta man, what a mighty good man. Sorry about that. Anyhoo, this is a mighty good MAN, built by Beat Felber of Flickr, and featuring remotely controlled 8×6 drive, steering on the first and second axles, motorised trailer coupling, working headlights and warning beacons, opening doors and hood, and a pneumatically tilting cab.

Lego MAN TGX Truck

It’s a spectacular creation, and it looks absolutely stunning on the outside too (and orange isn’t an easy thing to pull off if you’re a man). There’s lots more of this incredible creation to see at Beat’s photostream – click the link above to make the jump to the full gallery and technical details.

Miniature Minecraft

Lego Technic Mining Loader

We were a bit underwhelmed by LEGO’s 42049 Technic Mine Loader set when we previewed it here towards the end of last year. It has pneumatics and a two cylinder engine, but…meh. However a recent upload by previous bloggee Tamas Juhasz (aka mbmc137) shows how it should have been done, and at about half the scale.

Tamas’ tiny Technic recreation of the official set might be small, but it packs in just as much functionality, and in doing so it might just be the neatest and most well engineered small-scale Technic model we’ve seen this year. It could even be a set, if there wasn’t one already…

Lego Technic Mining Loader

With all the functionality of 42049, Tamas’ build squeezes in all-wheel-drive, articulated steering, pneumatic bucket elevation and tilt, and a two-cylinder piston engine (making it just as unrealistically underpowered as LEGO’s version).

There’s lots more to see of this incredibly tidy build at Tamas’ Brickshelf gallery and at the Eurobricks discussion forum, plus there’s a video of the loader’s features available below.
