Very good article!
Actually, if you read their Kickstarter, they claim to be getting better fuel efficiency with higher cargo weight. They claim this is because it somehow lowers their drag. They also claim that L/D is unimportant for…
That's not true at all. Their claims about wind tunnels are also ludicrous. Take a peak at the Reynold's number wikipedia page sometime. That's EXACTLY how aerospace engineers do preliminary calculations: by scaling…
