Of course, I was talking about the small remote controlled drones that can be used even in the small RC kit form to prove a plane before they progress to larger scale models. I am assuming that somewhere there are hundreds of small RC planes built at Skunk Works to see whether it was worth building a proof of concept aircraft. I thought the whole idea of a big proof of concept aircraft was that the design had been proven on a smaller scale and then they were scaling it up.
