Most RC scale builds only go as deep as the body, wheels, and tires. In the case of this astounding model built by Pierre Scerri, literally every part is scale, including the tiny ignition key that starts the fully-functional, gas-burning, 12-cylinder replica engine. This has made the rounds of the internet before, but it still blows us away every time. You need to see and hear this thing! Photo courtesy MPS Sport Proto (mps-sportproto.com).
