Please subscribe to our videos, this is the final assembly of a christmas present , it is a toy by MarioKart Kinetic....it had over 300 pieces, and said it was for 6 sand up....well, I challenge any 6 year old to put this together without adult help..My wife and I both took over 3 hours to do it...BUT, when finished , it actually worked with a bit of tweaking. Let us know your experience...thanks for watching.
