Sometimes it is nice to do a basic project, just the very basic tools, no glue, no paint and just create. I was given this Airfix model of an engine for Sinterklaas (Dutch tradition) and I wanted it for teaching my kids how the engine works.
It is an oversimplified engine, with just the very basics of an engine, but since it is see-trough, it does show how the engine works internal.
I think it took about an hour of 3 to put it together, basically without any issues, other than drilling the holes for the scews a little bit bigger, if you don’t do that, you ruin the screws and the engine doesn’t get together no more. It would’ve been nice if Airfix added a bit stronger screws.
