Victoria S. ★★★★★

The air-cooling design is clever—I can see how it will keep the engine running smoothly. Page 42’s assembly diagram saved me from a major mistake. This is the kind of project I’ve been looking for.

Avery C. ★★★★★

The 54 pages were incredibly detailed—every measurement was spot on, and the air-cooled design came together without a hitch. Fired up on the first try after following the plans closely, which felt amazing.

Brian ★★★★★

Got it built in about a week of evenings, and the 54-page bound format made it easy to keep my place. The air-cooled design runs steady once it's warmed up, and the four-cylinder firing sequence is a joy to watch.
