"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."
