Not long ago, Little Man decided to spend a bit of money on getting his own LEGO® set. Of course, he wants something that will move and isn’t too hard to build. He chose LEGO® set 42090 Getaway Truck. He told me later he picked that one over the Police Car because it had fewer parts.
This set is in the Technic line, and more specifically, it is a pull-back vehicle. Remember those? You pull them back and let them go.
Does he like it?
Yes, he does! So much so, he really wanted to demonstrate it for you.
Troubleshooting
Little Man build this all by himself. He followed the instructions, so he thought, but still at first it wouldn’t go. I looked over it and couldn’t figure it out, so got on LEGO’s website and got a chat started. I had just started chatting with the person when I found a random technic pin sticking out of a lift arm and rubbing a wheel. The removal of that pin did quite a bit for letting the truck go.
Later, when The Professor got home and Little Man was showing it off yet again, he, The Professor, found one tire was rubbing a lift arm. Separating those let the truck go even faster. I noticed the tires were not symmetrical, and upon closer inspection, found that wheel was put on backwards.
Fixing these 3 issues got the truck moving like we had expected it to.
What we learned
First, the LEGO.com chat option was truly helpful. When we figured out the randomly placed technic pin, and I reported we had fixed the problem, the person asked me to tell him (her? not sure) how we fixed it. I’m guessing they get the ‘ack it isn’t working!’ questions regularly.
Second, when it doesn’t work like you thought it would, when its LEGO®, you likely did something wrong. Just gotta start inspecting!
