    LEGO Technic - Mercedes-Benz Arocs 3245 (42043) is rated 4.8 out of 5 by 102.
    Rated 5 out of 5 by from Very rewarding, be very patient As I have been building the Technic sets since the very first car set back in the late 70's, though I missed a few in the 90's due to busy life, I can say this is the most challenging tech-build of them all to this point. That means it takes the place of the 5-Axle Mk2 Crane, Set 42009, with the biggest gear box and most transfer axles I can remember. This one made me write a card on the desk with "back up 2 pages and double check" my work. One missed transfer or gear, at the end of the modular section build system (very happy with this method), and your in trouble. Like others have noted, the hose routing instructions are very poor and I just went to using the completed model image pictures on the box and made it match. The air compressor idea is awesome and I really like the ideas of what this opens up for us to build in the future, but the compressor and its functions need some more work, and possibly a reserve tank. It does signal that future models will be large though and that means more real estate to park them on, always a good thing. In the end, a fantastic build and very rewarding when it all works. The age of the builder needs to be at the higher end as I don't see many 14 year old's with the patience for the pneumatic demands. The attention to the details, the models resemblance to the real world truck, twin axle steering, dual diff's, tilt cab, outriggers, it's just a great model and hats off to the LEGO engineer that brought this to life (got to be the best job on the planet, are these guys ever late for work). In the next pneumatic set, better instructions on routing and the board is all green.

    Rated 5 out of 5 by from Fun and detailed The above picture does not do this set justice. This thing is huge ... in a good way, though I can imagine there are even bigger Technic sets (i.e the Bucketwheel Excavator) Goes from intricate (gears and mechanical arm section) to easy (cab) Overall, a super build

    Rated 5 out of 5 by from Amazing, buy it NOW Wow. This set blew me away with the details and real life mechanics, and is by far the best Technuc set to date in terms of functionality, looks, overall playablity and value for money. The box is huge, and the 2800 pieces come in numbered bags. The build experience is truly fantastic, with many working parts and a pretty challenging ( but fun and worthwhile) pneumatic crane build. The end product is also spectacular, with many working parts and for looks by far the best Technic truck. It has interesting functions that are not dull, and a good looking detailed cabin too. My only problem is that the axle connecting the gear to the piston engine in the front of the truck keeps coming loose when I unhinge the cabin and I have to spend ten minutes trying to put it back so that the pistons would work. Other than that, amazing job LEGO and I look forward to the other flagship sets in coming years. If you are thinking of buying this, BUY IT before it retires. It is a once in a lifetime experience.

    Rated 5 out of 5 by from Best Technic Set to Date When someone asks what my favorite Lego sets are I immediately think of this one. A few years ago I ordered the Unimog set but never received it.:( Since then, they never had another pneumatics set. (except for the 42008 service truck but it was disappointing) I was excited for the new pneumatics system to come out, and it did not disappoint. This set is loaded with features, functions and details, and was very enjoyable to build. pros -decently large -many functions -new pneumatics -amazingly detailed (most detailed technic set of all time IMO) -New pieces -good suspension system -interesting steering system cons -disappointing outriggers, very small for a set this size -no cargo, I just ended up using the 42055 cargo -The crane is difficult to build with all the tubing going everywhere, hard to thread it through the holes (pages 284-289) Overall its a great set I definitely would recommend you get this if you don't have it since it'll retire soon.

    Rated 5 out of 5 by from Mind-blowing set Back in the late 80's/ early 90's when I was a little kid I had a few Technic sets and I really enjoyed putting them together. Now I have a little son who is super into all sorts of vehicles, so I decided to buy this set to stroll down the memory lane and see what it's like to build a modern Technic set, also knowing that my son will have something super cool to play with once I am done with it. The building process was very rewarding (especially putting together the engine, gearbox and steering), but also laborious at times (piping). It took me about 16h, and I am a bit surprised by how long it actually took me to finish it. All in all I enjoyed building this model a lot, and towards the end I was actually slightly disappointed it was going to finish soon. Some people complain about instructions not being clear - personally I think that LEGO did a sterling job of showing across nearly 500 pages (yup) how to assemble this truck. The end effect? This model is just phenomenal. It is humongous, so despite the price I think it represents a good value for money, and also it really looks very similar to the real-life Mercedes Arocs truck. Power and pneumatics functions are great, although I noticed that even though initially crane turntable was moving steadily and smoothly, over time movement started getting erratic (not sure if it is down to batteries wearing down, my son's antics with it or piping slightly getting in the way despite the correct laying). Hand-of-God steering could be better too, as the knob keeps falling off when you try to move the model on a rough surface holding it. Overall it is an epic set, and I am sure it is going down as one of the most iconic Technic sets ever released. I was thinking about buying it for a few months, as I had never spent so much on a LEGO set before, but in the end I decided to go for it and I am so glad I did. So if you are not sure if to get it - snap it fast, it's well worth it and might not be around for much longer

    Rated 5 out of 5 by from WOW! Out of my entire Technic collection, this is the totally best! Everything about it is so good! It is fun to build and really recommend it, you do need a little patience to build it, actually, no patience required! It was too fun to build!
    Date published: 2017-07-04
    Rated 5 out of 5 by from Amazing set very fun to play around with only thing i don't like is the steering is a little flimsy and when you drive it over something the wheels turn but good news is that if you wish to add power functions what i suggest is taking out the "engine" and the drive train and you can put a receiver or two where the "engine" was and a XL motor at the back of the truck with very simple modifications

    Is this model rc controlled does it move backwards and forwards?

    Asked by: Lisa 16
    No remote control. The motorized parts are the dump, the crane and the outriggers.
