"I have built A LOT of technic sets. This one fought me all the way. I found the instructions very hard to read, colors wrong on instructions, and missing pieces. I was excited to try the new controls- which seem cool, but the truck is stuck turning right, and wont move. Since it is all together, I cannot find where the problems are, and I feel with better instructions I would be enjoying right now. Unfortunately, I have a shelf dust collector.... I feel this one was a waste of time and money."
