Our friends over at RC Car Action found this. There are lots of functional miniature engines on YouTube, but most don’t sound nearly as good as this 1/3-scale replica of a Porsche Flat-6 circa late ’60s early ’70s. While most scale engine builders are happy to let their creations putt-putt, this builder (“a Dutch Porsche driver, and precision instrument maker”) winds it up and lets it sing! No wonder Porsche has kept this engine configuration for more than 50 years…
