A challenging and interesting build

I loved building this set. It took just over 20 hours to build from start to finish. This included sorting all of the pieces out before starting to build each section. This is something I always do as it makes the finding of pieces easier later on. I had no problems with the setup and control of the motors using the Lego Control app and everything functioned as it should first time through testing. The control and functionality offered by the app is really great and something that I felt was lacking from the Bugatti build.

Better to play with after it is built

The build is not the most pieces of any set, nor is it the most complex, there were no real problems building it and it was pretty straightforward. The only problem I had was solved when it turns out you ned to have all motors connected to the second hub to test it. This is not in the instructions, but calling support they are aware of it and just plugging the motors in will allow you to test part two. The thing is pretty heavy, the bag of 100 "rocks" is a good touch and it is how the LEGO group is able to claim that this is the largest set by piece count. Those pieces are not in the model unlike the rough terrain crane so I don't count them. When playing with it, make sure to stow the steps and lock them in place, I did not do that originally and caught it in the carpet. The controls are well explained and the app works fine on my phone. The model is very smooth compared to most power functions sets as there are not a lot of complex gears in the boom. The boom and bucket are all moved by linear actuators. The new longer linear actuator is soing to be something to play with in the future. All in all, a nice build, fun and heavy. Lots of replay value. Most of the expense is in the electronics and the license I suspect. But it is really fun to play with.

Great set

A fantastic set! I was expecting him (as well as 42110) since his announcement and I placed the order at 00:01 on 10/01/2019. Complex this set. Its construction was a challenge, with some mistakes, but it was worth it. Seeing the full capabilities of its 7 engines and 2 hubs was fantastic. And the simultaneous execution of various movements controlled by the Lego Control + App is new. Many possibilities offers the set, through firmware and software upgrades. Congratulations and continue on this path. One missing piece that the friendly and effective Lego Support service promptly sent. 5 stars for this service.

Emily, Customer Service
Thanks for your review. It's very unusual for a LEGO® set to be missing any pieces. (Usually they're found stuck in the packaging or hiding on the floor!) But in the rare case something is missing, we're always here to help at LEGO.build/Service. We're glad you got in touch, and happy building!

Great Build

Great model to build, instructions are clear and easy to follow the only problem we found was in testing 2nd stage was, you need to have all the motors connected, but this was a minor glitch. The down side we came across was, missing pieces, in bags 1,2 and 3, so needed to wait for replacement parts to arrive before we could complete.
