  • Lots of un to build
Fun to build and works. Good quality product that is somewhat difficult to build. Very small bolts and nuts. Instructions are mostly clear but don’t rely on the pictures as the sole source as it sometimes shows parts attached that actually get attached on the next page or two. One gripe, should have a pair of hobby tweezers included and a little better tools. ... show more

  • Overall good
Enjoyable to build and learn the process of a engine. The water inlet and outlet pipes are rather loose and fall off. A small wrench or pliers would be beneficial for the nuts and tight fitting parts. Overall though very good for fun and learning.

  • Worth the money
This is a fun build, I thoroughly enjoyed it. I wish I would have read the directions a little better though because I struggled putting the radiator together since I didn't bolt it as I went. Very good quality.
