Ok, this model's a masterpiece if I dare say. It does have some mishaps but mostly, it's the best bang for a buck if you're Technic builder. This set is a dream come true for you technic MOC builders. A lot of those 'new' connector parts, humongous wheels, and the LIME color! Even though you're not planning to use its parts, it excels 42056(yeah, that hyped Porsche) in many ways: 1. Many functions. Selectable steering modes, moving cockpit, crane operates, carriage can also be adjusted, and lastly, opening hood. This is a lot more than one can ask for a $179.00 set. In terms of functionality, this set is on par with 42043, IMO. 2. Looks awesome. I guess LEGO is driving Technic to some other (and way better) level. It LOOKS SOOOO GODLY!! Yeah, this set shines with tons of functions yet those working parts are hidden perfectly well under lovely huge wheels and panels. I guess this agenda(?) was the 42056 was aiming for but fallen a bit short. 3. It's HUUUGE. The finished A model (B model isn't so exclusive, though. It's more of a different attachment not a completely different model.) is as long as the flatbed portion of 42043 (Arocs Truck in my recommendation list.) B model and a bit wider than the truck. 4. It's modular!! The crane and the counterweights are just add-ons. In other words, if you can match the attachment mechanism (both front and rear attachment points work same way,) you can attach anything on it. 5. It's repeating but the wheels are sooooooo lovely!! I'm thinking getting another one to just get the wheels!! 6. The entire model is actually 'ROBUST.' Just don't try to pick it up with cockpit or hood. Other parts are solid as rock and completely playable. The building experience can be painful if you happen to be careless and slightly miss any part on early stage since the entire tractor is made of complex steering and cockpit rotating mechanisms and they are tightly fit and covered perfectly with control panels and the huge wheels. In fact, this is a plus for a Technic set since the whole theme of the Technic is an implementation of complex mechanisms, anyway. Admittedly, I screwed up something in early stage and had to take apart everything to start again. That's why I took 8 hours to complete. It could be 4-5 hours to reach 100% build. A bit of drawbacks are... 1. The steering mode change joystick(?) moves when you try to steer. It doesn't change the steering mode itself while steering but a bit annoying. 2. The steering mechanism has a lot of backlash. 3. You need to almost re-design the entire chassis to motorize the wheels and steering. But then again, this is a welcome challenge for me. Overall, it's the best Technic set I've ever built. A lot of functionality, nice looking, awesome build experience, and playability. What can I ask more? I doubt it. PS. You can mount a minifigure (if you have any lovely one. Regrettably, I don't since I'm mostly dedicated to building mechanisms.) in the cockpit!!
