STEMnex V8 Model Engine

This is such a perfect item for middle and high school students that have a great attention to detail and love working with their hands. My son was so happy when he completed it because it was something done entirely by him over the course of several weeks to months.

Hey so built this model with a friends kid who i bought it for around xmas. However the first time around i had issues with the pistons stricking valves. After some searching i found a mistake in the manual. Cam lob 3 and 4 and 5 and 6 needed to be swapped with eachother. Because the orientation in the picture did not match the orientation once all the pieces were put in order 1-8. After i swapped 3 and 4 and 5 and 6 it matched the picture and worked when i ran it. The order i had them in went 12436578 which like i said matched the picture

I bought this for my handy 15 year old son as I thought it would be a good intro into engines. He enjoyed it and completed it in one day. You could spread it out by having them complete the readings and associated build, having them disassemble and complete by memory, as well as learning all the technical names. I marked it down only because it is on the pricier end for something that is completed in a day. I didn't mind the price as I have multiple children that will use it.
