Designing with Technic panels and liftarms is never an easy task, and usually the result is either a total win or an awful failure. Sometimes stickers can transform the model’s boring look, but as I mentioned above the set of stickers for the crane is purely complimentary. The crane’s entire look is done through a very fine choice of panels completed with a wide range of small details and accessories, like this very cool fire extinguisher attached right behind the cab. There’s also a corresponding sticker right underneath it.
First - the box. The cardboard is thick, the box has a top and bottom (two parts), and a large vibrant picture of the model. When you open the box, you do not find a sea of plastic bags as with other Lego sets. Instead, you find four numbered boxes, four special edition wheels nestled in their own cutouts in a cardboard insert, and a large manual bearing only the Porsche logo on the cover. The manual itself is nice enough to be a coffee table book.
The intelligent brick can be programmed using official software available for Windows and Mac computers, and is downloaded onto the brick via Bluetooth or a USB cable. There are also several unofficial programs and compatible programming languages that have been made to work with the brick, and many books have been written to support this community.[52]

One of the most anticipated tests of the crane is its lifting capacity. LEGO Technic cranes have never been among the best top-lifters; the second biggest LEGO Technic crane, 42009 Mobile Crane Mk II could only lift about 500 grams/1.1 lbs of cargo. Surprisingly enough, the new mobile crane is capable of lifting twice as much. We managed to make it lift up to 1.1 kg/2.4 lbs of Pepsi cans before the winch mechanism started to give up. Loading the crane with heavier cargo can result in severe damages to the turntable mechanism, so we won’t recommend pushing it to the limits.


LEGO suggest this kit for 9-16 year olds, however many adult reviewers are also very pleased with the quality of the product. The tracked wheels mean the vehicle can be driven over a number of obstacles and it can travel up to 1.5 mph. Everything is included from the remote to the motor, however, it is necessary to buy both AAA and AA batteries for these to work.
In December 2012, the BBC's More or Less radio program asked the Open University's engineering department to determine "how many Lego bricks, stacked one on top of the other, it would take for the weight to destroy the bottom brick?"[44] Using a hydraulic testing machine, the engineering department determined the average maximum force a 2×2 Lego brick can stand is 4,240 newtons; since an average 2×2 Lego brick has a mass of 1.152 grams (0.0406 oz), according to their calculations it would take a stack of 375,000 bricks to cause the bottom brick to collapse, which represents a stack 3,591 metres (11,781 ft) in height.[44]
WARNING!!!...the following post sounds like I am gushing (which frankly I am), ....Oh wow Eric...you don't even realize it but it is all YOUR fault. About a year ago when I discovered bricklink and started collecting I stumbled across Technicopedia.  Hours and hours later I realized that I had quite a bit more collecting to do to "catch-up"..... If it were not for your influence I would have never known so many unique technic creations had been produced.... Anyway, I blamed you then and I will blame you again now....you did this....and I couldn't be more thrilled.
These Lego building sets are great toys!! I ordered this one next day and it came fast and on time for my son's birthday. My ten year old loves to build these!! If you have a child who likes to build things this is the toy to get. My daughters also love these so great for boys and girls!! It is a smart toy that makes kids use their hands, follow directions and exercise perseverance. It will take him a few days to get this built and definitely worth the effort.

Beams - Beams are long blocks with rows of round holes. All beams are one stud wide, but they can have varying lengths. They constitute the basic structure of the TECHNIC system. Before 2000, the TECHNIC system used TECHNIC bricks, essentially standard bricks with holes along the sides. Beams are part of "studless construction", which allows TECHNIC models to be more compact. They have rounded edges and no studs.

In addition to standard gears, some kits include a rack, a clutch and even worm gears and differential gears. The original differential had a 28 tooth bevel gear, designed to be meshed with the 14 tooth bevel gears (replaced by the 12 tooth gears) to give 2:1 reduction. They can also be meshed with the newer double bevel gears. It was replaced by a newer design incorporating 16 tooth and 24 tooth gears on opposite sides of the casing. The casing holds three 12 tooth bevel gears inside.

By 1954, Christiansen's son, Godtfred, had become the junior managing director of the Lego Group.[13] It was his conversation with an overseas buyer that led to the idea of a toy system. Godtfred saw the immense potential in Lego bricks to become a system for creative play, but the bricks still had some problems from a technical standpoint: their locking ability was limited and they were not versatile.[3] In 1958, the modern brick design was developed; it took five years to find the right material for it, ABS (acrylonitrile butadiene styrene) polymer.[11][12] The modern Lego brick design was patented on 28 January 1958.[15]


Technic has certainly produced a lot of large models this year. Only 5 out of the 12 sets this year are under $50. These three are the best of them all, in my opinion. The accuracy of detail in the Volvo EW160E and the CLAAS XERION, combined with their functions, make them truly great sets. Now, the BWE is indeed the largest Technic set ever by piece (it’s 7th largest overall) and probably size, and it’s my favorite of the three. Its poor performance, however, lets the model down somewhat. I think it needs 2 XL-motors, not one, for power. The Mobile Aggregate Processor works okay, though, and it looks quite cool. Sadly I will have to pass on it, in favor of many other sets this year. 🙁
Bought this to add on to the 24-hour race car (42039), to add motor operation to door and hood opening and closings, and especially to add headlights to the front of the car. Adding it onto the car was quite simple, but this quickly led to some disappointment when I found that the headlights didn't work independently of the motor. To have the lights come on, you must switch on the power unit that also controls the motor, and while I could leave the door/hood operation in a neutral gear to not activate, the motor whirring just to have the lights shine is a bit of a letdown as I'd like to have just the lights on for a display in the evening (it's in the man cave, so when friends are over, etc.). But it does really enhance the model watching the doors/hood go up and down, but wish I could operate the lights by themselves. Guess I could disconnect the motor operation to have lights only, and then re-attach when needed.
I bought this set on its release day and I couldn’t be happier with it! Excellent write-up, and I couldn’t agree more about wishing that LEGO gave you some directions on how to test all of the gearing on such a complicated gear box before you start fully covering it up! When I got the motor installed and fired it up, nothing would move and I was not looking forward to taking apart so many pieces to find the mistake. Fortunately, I had simply forgotten to engage the upper/lower switch…once I flipped that, everything worked! Talk about a relief!
Although I’ve not built many Technic sets, I had a few when I was a kid and in recent years tackled the VOLVO L350F Wheel Loader. Things have changed greatly between the sets I built in the 80s to Bugatti. The new Technic system which was introduced in the early 2000s has lead to a collection of models which continue to innovate and challenge. Would I of have purchased this set, if I didn’t have the opportunity to review it? Probably not but I would be missing out on a genuinely unique LEGO experience. An experience which begins from the moment you lift the lid and feast your eyes upon its perfectly arranged boxes.
Yes, the only issue is that it is really expensive. While there is cool detail, authentic interior and genuine mirrored instructions, this might be out of the price range for many, but if you have the cash, then don’t hesitate to get your hands on one of the finest sets LEGO has ever released. Or this can make a great Christmas gift for your loved ones.
LEGO Technic sets pride themselves on offering builds that’s not only challenge those constructing them but also by providing a truly technical feat. This start of the build is certainly the most involved as you engineer the guts of the Bugatti. Here you’ll find a mind-bogging mix of gears, pistons and pins. One of the most important pieces of advice we can give when building this set or any in-depth Technic set for that matter is to always test any sections which feature gears. If you’ve put something on incorrectly or in the wrong hole, you’ll run into problems further along in the build. The engine included in the Bugatti, features two crankshafts, which power a series of 16 pistons. These will run as the wheels turn and can easily be rendered inactive if a pole or peg is too tightly fitted or place ever so slightly wrong.
The pneumatic elements are most commonly used to resemble and take the function of hydraulic cylinders in appropriate models, actuating a digging arm or crane, for example. They can, however, also be used to build a pneumatic engine, which converts air pressure into rotary motion using the same principles as a steam engine. However, the cylinders are not optimised for this purpose, and such engines tend to be slow and lack power unless the cylinder inlets are enlarged.
With these sets it is possible to build or convert manually-operated mechanical movement to motorized using electric motors which are controlled via switches or IR remote control. Future plans for this set include more parts which will add even more function/control possibilities.[citation needed]. Lego has already started to design and sell Lego Technic models (sets) which can be easily retrofitted with the Power Functions system. For example, models like the 8294 Excavator and 8295 Telescopic Handler are sold like classic Lego Technic models with manual motorization but are designed with free space for the Power Functions components with factory instructions on how to perform the conversion to an electrically operated model.
I just wanted to tell you that I love your LEGO Technic site.  I unearthed my old Technic models a while ago.......At that time I thought to myself: "There has to be some kind of LEGO Technic fansite on the net", I needed more information about the things I missed during those 10 years. I started searching, and imagined what the perfect source would look like, and well then I found it in the form of your Technicopedia. Its not only the highly detailed descriptions, but I love it when somebody combines great insight with a casual, personal style of presentation.

The perfect LEGO building kit for both car buffs and Technic collectors, the Mercedes-Benz Arocs provides a detailed and enthralling experience. One of the largest sets available, this 2-in-1 model comes complete with authentic detail, a massive power functions motor and advance pneumatic system that controls the crane arm and grabber, tipper and outriggers.
