This is far lighter and significantly different from your usual diesel, though. It's an all-aluminum design and weighs 250-300kg. Heavier (for the same power) than competing turbine engines (like, say, the ubiquitous PT6?) Sure, absolutely. Crazy heavy? Nah. The entire thing probably weighs somewhere around 2000-3000kg (veeery roughly) if I had to guess. So the extra 100kg or so isn't a total dealbreaker, if they can make it up elsewhere. Very interesting aircraft for sure. I'm still skeptical, but hoping it works out, and rooting for them!
