    If my life were to be sponsored by a company it would probably be lego. As a child every christmas either featured lego as the main present from santa or was a major factor on the agenda. As a "grown up" I have pretty much indulged in one of the big sets each year for the past 6 or 7 years now whether that be giant R2D2 or a pair of horizon expresses.

    On this basis, I would say that this set was not my favourite, but it was still certainly excellent fun. However, recalling being a child and enjoying de-constructing sets and making my own thing, this set would have been legendary. There is such a wonderful array of pieces to play with and with power functions and pneumatics, together with steering, tilting tipper, suspension and differentials in the build, all manner of possibilities.

    Additionally, when looking at the price point (base lego price is £170 but often cheaper here) compared to the number of pieces you get, this is a very good value set, particularly if like my childhood self, there is a burning desire to simply have more lego pieces than you know what to do with. As an example, the star wars sandcrawler has a few hundred extra pieces but the price point is nearly £100 more.

    On to the build itself, this was certainly testing, particularly the crane arm. I am pretty sure 12 year old me would have coped with it perfectly well though and it would have kept me quiet for a very long time and probably secured compliance and eating of vegetables without complaint for some weeks. The finished product is very smart looking with good attention to detail and makes a fine addition to my bedroom window sill.

    Excellent product, and great amazon service. Delivered a day before estimate delivery date.

    I found building the model pretty straight forward. Most of the bags are numbered for ease of building and the instructions are very clearly printed and easy to follow. There are c 2500 pieces in the set, and the instruction manual is just shy of 500 pages so not for the novice builder. The model took me aprox 8-9 hours to build.

    Product is very realistic, just like the Volvo loader from last year, and on the box are some pictures and specs of the real thing. Has plent of movement - outriggers, tiping cargo hold, rotating grabber. Phumatics to control movement in the grab, though the only downside is that lowering the main/bottom pump results in a very quick uncontrolled drop of the arm which is not realistic. Otherwise really good, fun and educational model.

    WOW I love this model. It is huge and I mean HUGE. It took me 5 days to build this beast. The motor provides power to the tipper body so it can tip it's load, to extend the stabilizers and also to power the pneumatic pump that in turn drives the crane. The cab doors open as they should and the cab itself weirdly tips forwards. The suspension springs on the rear axles are nice and soft and the ones on the 2 front axles are a bit firmer and the steering is easy to turn. This is the best LEGO Technic truck model I have bought to date. It's just like the real thing bar the cabs tilt. BRILLIANT! I haven't built the secondary model yet, but I'm sure it's as impressive. I wonder what great model will come next.LEGO Technic 42043 Mercedes-Benz Arocs 3245 Truck

    I'm 43, so maybe I should be playing with real cars by now, but its still my favourite Xmas gift-to-self. When my mother in law starts telling me about her failed hip surgery, or my wife tells me to get fire wood, or the kids ask me to go outside in the snow for a bike ride, I can retire to the study with a mince pie for an hour of Xmas Lego. Delightful.

    The last Technics model I built was a logging vehicle around 18 years ago (set 8443 if you were interested) and while I was on leave I got reminiscing about building it and running the pneumatics. So, I naively thought, as an adult I surely will be able to appreciate the 'flagship' model for 2015 which not only has double the amount of rams but also motorised tipping, outriggers, crane turntable and pump!

    And thus began the most harrowing 72 hours of my life. (Actual build time was around 16 hours with breaks)

    Seriously though the build is very challenging and I wouldn't recommend letting a child attempt this without adult assistance unless they are a hardboiled veteran. It was interesting that the part I appreciated the most was actually the suspended double axle at the rear of the lorry and connecting that to the straight 6 'engine' at the front.

    The major flashpoints for me were connecting the pneumatic pipes to the valves and then mounting the completed cab to the front of the lorry. The first is a challenge due to the limited space and then realising that the cables are meant to be arranged 'just so' in order for the crane assembly to be mounted behind the battery pack. The cab was a problem as while the manual showed how to attach it, I found the space I had to work in meant I couldn't see what I was doing. In the end I just cheated and took the front bumper and side off!

    So what of the completed model? For the most part it doesn't disappoint however as mentioned by a fellow reviewer, the first ram on the crane does have a nasty habit of crashing down unless there is quite some pressure supporting the weight of the boom. I found that you really need to have a light touch on the valve and that helps.

    All in all this is a very impressive set but not for beginners or lapsed old-hands at all.

    5.0 out of 5 stars He quedado fascinado con este set del 2016.
    Reviewed in Spain on 14 April 2017
    Lego Technic es una gama de productos de Lego que van dirigidos a personas entre 10 y 100 años... a pequeños ingenieros, o ingenieros senior... yo no tengo 10, pero tampoco 100 y desde pequeño me encanta el modelismo y construir/desmontar cosas. Vi publicidad de este set y numerosos videos en YouTube de los llamados MOCs o modificaciones del set original y me sorprendió las posibilidades que ofrecía Lego Technic; yo he hecho muchas cosas con Mindstorms, pero el planteamiento de Technic me parece que tiene más posibilidades.
    Este modelo incluye un único motor, que mediante un ingenioso sistema de engranajes, hace hasta 5 funciones, tiene elementos neumáticos, se levanta la caja, se mueve la pala, se abre/cierra, sube/baja y se extiende. El acabado es muy bonito, y el camión es realmente grande; rueda muy bien. Sorprende lo bien diseñada que está la transmisión, la suspensión... se adapta muy bien al terreno. Tiene casi 3000 piezas y se tarda 20-25 horas en montarlo, tiene una cierta complejidad, pero el manual de construcción esta muy detallado. Con este set se pueden construir dos modelos, el camión de 4 ejes y tractora+remolque, aunque con esas 3000 piezas se pueden hacer otras muchas cosas, y todo tipo de MOCs basados en camiones. Una vez montado, te entran ganas de motorizarlo... y en ello ando.
    Para los iniciados en Technic no creo que tengan dudas (salvo el precio, que aunque algo caro, lo vale) y para el resto, si están dudando, la verdad, merece la pena.

    5.0 out of 5 stars Très beau modèle
    Reviewed in France on 16 May 2017
    Grand fan de Lego Technic depuis mon plus jeune âge (et j'ai 40 ans ^^), cela faisait longtemps que je voulais m'en racheter quelques uns. Mais la pression sociale étant ce qu'elle est, et dans ce monde où nous avons "peur" de ce que les autres vont penser, je n'ai franchi le pas que récemment. Car oui, à 40 ans, s'offrir des Lego, je pensais que c'était bizarre ou pour le moins immature, et en fait en lisant les commentaires ici ou là, je me suis aperçu que je n'étais pas si étrange.

    Je me suis donc offert ce modèle mais aussi le 42052 et le 42025 :-) (oui ça fait mal au portefeuille).

    Je dois dire que si j'avais déjà été relativement impressionné par le 42052, le Arocs est d'une toute autre envergure, c'est un monstre. Pendant tout le montage, je me suis fait la même réflexion : "Les mecs qui ont conçu ce modèle sont des $#*§" de génies" (rien que la conception de la notice, c'est du génie ^^).

    Ce Lego est très détaillé et possède quatre fonctions motorisés (rotation de la grue, sortie des stabilisateurs latéraux, contrôle de la benne et mise en pression pour le système pneumatique) + quatre fonctions pneumatique. Avec ces 2700 pièces, j'ai mis environ 12 heures à le monter sans me presser et en m'arrêtant quelque fois afin d'admirer le travail de conception, la seule "difficulté" est le montage de la grue, il faut être minutieux afin de placer au mieux les durites, mais c'est relativement bien expliqué dans la notice (comparé à celles de mes anciens modèles - qui ont tout de même pas loin de 30 ans, c'est le jour et la nuit)

    Les différents essieux ont tous une suspension, les deux essieux avant n'ont pas le même angle de rotation, les essieux arrières (avec différentiel) entraine le moteur sous la cabine (qui basculer vers l'avant afin de montrer le dit moteur). Le boitier de pile est parfaitement intégré et il est très facile d'accès. Le seul petit bémol concerne la benne, en effet elle est entrainée par un piston à rotation et la fin de course n'est pas géré, il est donc important de l'arrêter manuellement assez vite sinon cela craque fort et ça risque, à terme, d'abimer l'engrenage et/ou le piston.

    J'ai hâte de monter le modèle alternatif.

    Bref, ce modèle est parfait, si ce n'est le prix qui est tout de même relativement conséquent. Mais la qualité et la conception d'un tel modèle, ça se paye.

    5.0 out of 5 stars Fantastico!
    Reviewed in Italy on 22 September 2016
    Inizio col dire che sono fanatico di questi modelli, un po' perchè richiedono tanto tempo per il montaggio e un po' perchè si rivalutano nel tempo.
    Il montaggio ha impiegato circa 7 ore, ma senza particolari difficoltà.
    Non avevo mai avuto un modello che pistoni idraulici che si attivavano elettronicamente. E' sicuramente interessante e affascinante il loro funzionamento che però non mi sento di dire sia "perfetto". Sicuramente dietro c'è un lavoro notevole perchè se si guarda sotto la gru si può vedere quanto sia stata complicata la realizzazione.

    Il pianale funziona perfettamente e le assi mobili su cui poggia questo truck danno un'idea di realismo notevole.
    Consiglio l'acquisto a tutti gli amanti del genere!

    5.0 out of 5 stars Fantastic...
    Reviewed in India on 15 February 2016
    This is a fantastic set, the largest one that I have. Having more than 2700 pieces, it took me well over eight hours, spread over two days to build it. The colour combination and overall proportions make it stand out as does the size which is around 500 mm.It's quiet heavy too at around 2.5 Kg. There are many unusual details in the build, and these are good to know (e.g., the front grill details).

    Unusually for a Lego, two small pieces were missing right out of the box (no, they did not roll under the bed and I didn't lose them), and I used ones from my other sets to make it up.

    One thing though, don't expect the pneumatics and power functions to work like the videos you may have seen on YouTube. They work, but not in a satisfactory (or satisfying) manner. The power functions are under-powered and that is disappointing. The pneumatic controls are fussy. But despite all that, this has to be my favorite Lego model (for now).
