"I'm new to the lego world and want to commend the designers of this set! It is an awesome build, well laid out and it just amazes me with the amount of detail they put into this set. I am halfway done and cannot wait to finish and let my son play with it, he has been helping along the way with the organizing parts for the specific steps. I love the transmission and gear layout it really was fun for us to put them together and making sure they move smoothly.
