    Look cool though; https://www.youtube.com/watch?v=6pBxqUG4cfk

    Bohannan entered the aircraft in the Reno Air Races in 1994, qualifying in third place in the Formula One class, with a speed of 236.153 mph (380.051 km/h).[1]

    In 1995 Bohannan flew the aircraft to second place in the Formula One Gold championship race at Reno, Nevada.[1]

    Late Paul McCready developed fully solar power airplanes....with 10% efficienct panels.

    Now they have 3 x the efficiency.

    Are we missing something ?

    Delta DYKE is a flying wing.

    NASA is researching the flying wing. Also the blended wing is coming.

    Here Albion Bowers and the Mars conquering flying wing; https://www.youtube.com/watch?v=w-dk1NpVNNI

    I still wonder how come the flying wing hasn't taken the scene yet.

    I think there is an answer. Something hasn't been discovered yet.

    It must relate to stability at different flight patterns.

    FPVWRA (wing racing association) is all wings. I raced in Spec class this year and it was a lot of fun at 70mph. The Sport class gets up to 120mph. I think the wings are used because the foam is really easy to cut and build and it's easy to put the prop in the back so the propeller doesn't puncture the inflatable pylons.

    I did talk to one of the guys spearheading the BSLD (bell shaped lift distribution) for wings and he said there are very particular conditions where wings are better than standard aircraft, and he didn't think racing was one.

    How about this...420 km/h on electric.
