You May Have Built a Model Car Before, but What About a Running Miniature Engine?

If the unofficial GRM model contest proves anything, it's that building smaller versions of cars can be just as much fun as building full-scale ones.

Does that same enjoyment carry over to building miniature engines—ones that actually run?

Whatever the case may be, there's something fascinating about these model powerplants. There are a few V8s, a flat-six and even a coin-balancing W32 setup—all miniature.

Listen to these tiny engines run over on Classic Motorsports, and let us know what engine you'd like to make a miniature version of.

There's a meet for these critters every Spring just south of Detroit ( I'll try to look it up and post it later). Some of the workmanship is astounding. There are also complete cars and chassis on exhibit.

Okay, here it is: it's the North American Model Engineering Society Exposition, normally held in Wyandotte, but obviously canceled this year. My brother and I attended this and were blown away by the work these guys put in. I think all GRMers would love this show.

JohnnyQ90 made an entire RC car including a V-4 engine. Not exactly the same thing since his is not a scale model of a real life engine/car, but it is cool to see his progress as he goes along.

So, Ferrari used two pistons per cylinder ?? I'd love to see that in action.

I've put a couple 50cc motors together. That's miniature in my book.

^ counts in my book.  I rebuilt a 4 stroke Yamaha golf motor this spring, and actually learned a ton about motors in general.  As an added bonus, the golf cart runs awesome and is way more useful than I would have guessed.   I've got BP motor parts all over my garage, at this point I'm much more confident to plug ahead and do a motor rebuild for the SM.
