They are MODEL engines and are not "man rated" by the FAA. There are several YT vids showing how they are built and assembled. Watch these and then determine if you ever want to put your "skin on the line" using one. By comparison, the Williams FJ-44 is a small TURBOFAN originally built to power US cruise missiles. It had to demonstrate extreme reliability before it was FAA certified and man rated for use on very light business jets. Not to mention it was originally designed to stringent military specs. Bottom line again, these are model TURBOJET engines. Never put your safety/life in a position where their reliability matters.
