68 horsepower per liter! Air-cooled? You betcha. This hand-built V12 engine, the fruit of hobbyist Ralf Drendel's labor, clocks in at a mere 87 cc's of displacement and cranks out a
whopping mere 6 horsepower. That's three times the pistons of the worlds smallest 4 cylinder and probably three times the headaches. The little terror was designed with RC planes in mind, but it's so thirsty its creator is having second thoughts. You wouldn't believe how hard it is to find pictures of the beast, but the video, as you can see above, is utterly glorious. Hit the jump for a picture of the mighty mini wonder.
