I gifted my husband this set for Christmas and he just finished it. It was a super fun build and it works! I have volunteered for FIRST Lego League for 15 years so I have a garage full of Technic. I was able to pull 90% of the parts from my stash. I cost roughly $100 to buy the gold and silver parts and the few other parts that I didn't have. It's a lot bigger than it looks. I'm not sure where its going to live. Its been on a table in the family room for a month getting built. submitted...
