So, part of the challenge when you work intermittently on a build, you might make a mistake. Yesterday I found out I was one peg over too far in the Porsche build, having to teardown and rebuild the gearing. Here is an image.
I didn't mind it as much though, I had sorted the parts previously since this was a used set. So far, the only thing I am missing is the secondary sticker showing the track layout. Id really like that, but otherwise, this build IS very awesome and I am glad I purchased it. Next will be to get the Bugatti and then the Lambo. I might even have to rebuild my 42000 Set from storage. Ive really been on a Technic kick lately.
