Electroflight Engineering Mockup

Some people in England are trying to build a battery powered, electric racing airplane. That's a full size airplane capable of carrying a pilot, not a miniature radio/controlled toy. They claim all kinds of impressive capabilities, but they haven't built a real one yet, so we'll have to wait and see if it will really be able to climb straight up at 100 MPH.
  Curious thing, they are using contra-rotating propellers ala the Russian Bear, er, not that bear, this one. The are using two separate motors to drive the two propellers, so no expensive gearbox like the Russians, so it's kind of like a conventional twin-engined airplane in that if one motor fails, you still have one left. But that's really not a problem with electric power, is it? After all, the capacitor that blew out for no good reason on my computer's motherboard didn't cause my computer to quit did it? Oh yeah, that's right, it did. Stupid electronics.
