    42043 Mercedes-Benz Arocs 3245. Best Birthday Gift
    | 25-34
    I would recommend this to a friend!
    Purchased for: Self
    This is what a 2.793-piece set gives you, at $229.99 you get one of the best Technic sets in Lego history. The 42043 Mercedes-Benz Arocs 3245 and it's B-Model Arocs 1845 is the successor to the well-received 8110 Mercedes-Benz Unimog U400, whereas the latter was designed as an all-around go anywhere model truck, the Arocs is a heavy duty construction truck, think of it as a Mercedes-Benz Actros that went to the gym and decided it will work at construction sites for most of its life cycle. The biggest factors I was worried when I first heard Lego was making another Mercedes-Benz model were if the truck has a dually setup and a proper Straight-6 engine which I'll get covered throughout my review. First things first, this is a superset and currently holds the record for being the biggest set in Technic history and the third set to pass the 2,000-piece mark that was a feat made by it's predecessor 8110 when it came out with 2,048 pieces. The truck is not quite as striking in size as the Unimog but you can tell that it's big because of the striking height and the amount of detail it has. This set is not your usual "I'll do this is 8-12 hours straight" which I'm fond of doing when I get my large Lego sets. It took me close to 20 hours spread over 5 days to complete it, you'll appreciate every detail put in this model as you complete the 6 sections (I decided to modify/ change some parts that's also why I have nearly 20 hours put in this build). Bags came numbered to 6 sections so even if it is a challenging build you won't have a hard time trying to figure out where's that part which I really appreciate from Lego. Being based on an actual truck, the 42043 has details like a working suspension system, a proper drivetrain, and dually tires. As far as the suspension is concerned, this is one of the most advanced one I've seen in a large Lego truck after 2 years of buying vehicle sets, the front suspension stands firm to hold the weight and the same goes over the rear, Lego used the new ball and socket suspension parts to replicate the real truck's leaf spring setup, for a truck this scale the suspension works very well. An industry standard among heavy trucks (Class 8 and above) is the usage of Inline-6 cylinder engine, these are large displacement units which compared to V-8s, V-10s, V-12s are very efficient and both A and B models feature the same I-6 setup, you roll the truck you can actually hear the cylinder heads moving and it is connected to the rear axles. As far as differentials are concerned this has 2 of them which was missing from the 8258, 8285 and 9397 models as a result you don't to buy the differential or find one from your spare parts bin. another touch of detail that I really are the wheels and tires, yes they are small (I wished Lego designed a larger diameter tire for this one) but you get 12 of them and the real truck's dually setup was carried over to the model we have. The HOG steering system is one of the best I've seen, it's not a new approach but a rare method used for Technic sets (I guess), you have these beacon lights that are connected to the HOG steering shaft the steers all 4 front wheels and this results to "hidden" system which in turn gives the truck a smooth looking finish. One of the set's biggest highlights is the Pneumatics 2.0, these are longer and stronger pneumatic cylinders with a redesigned port for connecting the pneumatic pipes (these pipes come pre-cut just get a ruler to make sure you're connecting the right size to the right spot) and they do the lifting duties for the crane which almost looks like the Palfinger units we see in Unimogs, Zetros, Actros, and Arocs trucks. These units are strong and able to hold air better, at it's end is a pair of clamshell buckets that can hold small parts and I really love this approach. While previous sets featured an M-Motor to do all the Power Functions features, this and the 42042 follows the footsteps of the 9398 and 41999 Rock Crawler sets, it's strong but not as crazy strong as an XL-Motor. It has enough torque to power all motorized features you get in this set. Outriggers, they feature new parts which is also featured in the pneumatic crane, the new design is 14M long and is strong enough to withstand stress when extended and used to lift the truck's front section and NO you don't push the the manually operated parts to it's maximum because it's not really going to work, you might end up breaking a small gear because that's not how it's designed. You operate the outriggers to the extent it will make the truck stable while operating the crane. Tipping function is superb, there is only one large linear actuator but it works seamlessly, the bed felt small for me so I made my version taller, still works fine. While some might complain about the outriggers that they are suited for terrain or over similar environment let me point out that this model - based on the Arocs 3240 grounder - the type of truck you'll see in construction sites and not in mining sites so it's much more of a "I'll go the site and clear out large stones, sand what have you" it's basically a road going truck with construction in mind. You get to play it's functions even better with the new transmission pieces first introduced in the 42039 Le Mans car, unlike the old transmission piece, this one holds the other functions steady and not move, and YES you can operate 2 functions at once without fully damaging the set though I still wouldn't do that. A note when building the crane too: As it rotates to only 180 degrees, it will be achieved if you test and just bolt the pipes in, mine works just fine and so far I haven't encountered it not doing the 180. I guess it's just on how it's built by it's owner. The cab design is clean and you can actually move it to reveal the Straight-6 engine underneath, doors open and there's even a handle and extra sidestep on the driver's side. I did some video research on the truck too and I found that there is an Arocs model that features the 3-slat design for it's grill, the video is in Youtube and it was released just right at the same time the Arocs was. Lego did an amazing job designing that "toothed" grill along with the use of flick-fire missile parts to hold the flat panels. There is one thing that really caught my attention when building this model, I had to call Lego Customer Service because one of the bags (bag tagged #3) was opened inside the set, I was supposed to build it on my birthday November 2nd but was forced to do an early build because of this issue well luckily the bag was only opened and wasn't missing any parts because that will have been a bigger headache. I hope the bags are tougher to avoid this little issue. Your people at Customer service are very courteous and assured me if there was indeed a missing piece it will be sent to me. SO will I recommend this set? YES, get this and you will not regret it. A fantastic set for young truck lovers and collectors of any age, it clearly achieves it's purpose as a toy that is a sold 100%, tons of detail and I can spend all day just staring at this set, I think I have never seen a very detailed Lego Technic set as much as the 42043 Arocs is right now. For one to even fully appreciate the set in it's entirety I wouldn't make it RC I mean that's just how I see it, that little kid in me still wants to be the hands on collector, operate the functions and make sounds as if it was really real. I had such a great time building this set that recommend this to every Lego fan out there, as a purchase or gift I'm sure you'll never regret spending $230 for this big guy! 100/100

    From start to finish this model keeps you on your toes, no short cuts allowed or not reading the page properly as I found out the hard way, one small axle does a lot of work. Amazed how every thing was crammed into such a tight space whilst still giving all the functions of the real machine. The pneumatic system, extending boom excellent fun, the controls are very sensitive till you get used to them. The size of the model is excellent, you can get loads into the tipper and the suspension works a dream. Model B looks another excellent build. Excellent flag ship model for 2015.

    This was great fun. Took my time and made the build last for 18 hours. 6per day on a Fri, Sat and Sun. A bit pricey but totally worth the money. Lots of great pieces and new ways of making incredibly cool functions. The chassis suspension, differentials and drive-shaft were my favorite part. It looks amazing from underneath when you pick it up and look at the final product.
