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.

Addicted to Lego Technic

This is my 5th Lego Technic set and the biggest in size and pieces, I have the Ferrari on lay-by at a local store. I enjoyed building this set every moment was fun and sometimes challenging, I have learnt from my previous builds to sort the pieces first to make it easier to find what your looking for! I couldn't tell you how long it took to build but it was finished too soon. My TV can mirror my phone so I set up in front of it and have my instructions on the big screen which was so much easier to see what I had to do. I was missing 1 little piece that is on its way but it thankfully isn't an important piece and was able to finish the build without it. I look forward to building plenty more Lego for years to come. Thank you Lego for such amazing kits to keep us big kids building…

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.

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!
