Great engine build for our grandson 9 years old and older kids who love to build

Great product!

Went together fairly easily although some instructions needed a little more info. Although piston movement was good, it is hidden by other parts when the model is complete.

This was purchased as a gift for my grandson and he loved it.

I bought this kit for my husband, who has torn down and rebuilt more engines than I can count. The instructions with this kit are ridiculous. It's all pictures (poor ones) with arrows going every which way and no specifics about how to put the kit together. My hubby will muddle through and figure it out, but don't purchase this for a first-timer or someone who doesn't understand what the components of an engine are or how they are supposed to go together!

Was fun to build but turning parts hardly stick together long when running. The picture also shows a clear crank cover, but in truth its opaque and you cant see much of the running pistons when its assembled. But it was a fun learning experience.

Great little buildable engine. I purchased it for my 13 year old and he loves it.

Super fun. Very detailed. Well made
