    Could you design anything stranger?

    While you're at it, propellers that make a good microbrew would be nice. ;)

    Pendulum effect, vertical position of CG

    I preferred supine under the bar to prone harnesses for hang gliding for 3 reasons. Never liked supine over the bar. ( suprone... silly name but does give a distinction ) That's 2-3 feet lower than "normal" . Comfort. Easier on the neck, than prone, but you need a headrest on the supine...

    Pendulum effect, vertical position of CG

    That's more a matter of simplicity of construction, keeping a clean wing center section ( without gaps or bulges ) and putting the variable weight, the pilot, in the right spot. than a vertical distance. Paragliders, balloons, and other flying things that have a flexible connection to the...

    Forget electric flight propulsion for a minute. Electric *taxiing*???

    This isn't the "I want to put a Locomotive generator with a P&W turboshaft in my Firefly, and will ignore the 3200 pounds of heat exchanger needed to keep it from melting" or the "I look forward to the dilithium crystals that have been promised for next year for the last 6" or the "Electric...

    Pendulum effect, vertical position of CG

    Vertical position of the CG is more often a powered plane issue, when the thrust line is high ( Or low, but that's rare ) in relation to the CG. In a glider, the stability forces in pitch act through the fulcrum of the center of lift on the wing, and the tail. On a tailless plane. It's often...

    Could you design anything stranger?

    Yes, that was a problem back in 1976. It got solved. Then we pushed the envelope more and found other problems. :) The current versions are higher aspect ratio, have much better aerodynamic drag and can recover from very unusual attitudes. I still wouldn't want to stall into a tail slide unless...

    Forget electric flight propulsion for a minute. Electric *taxiing*???

    Going to a very different power plant offers unique benefits if you design around the perks. Possibly the best example is the small diameter of the electric motor, allowing less frontal area or better streamlined cowl. Much like V12 engines vs. Radials in the fighters from the 1930-1945 Era...

    Could you design anything stranger?

    I've jumped the Paradactyl myself, snappy opening shock with no slider & decent glide... Compared to a T10. ;) I really liked it. Even flew one off a ski hill. In contrast, my "standard Rogallo" hang glider got about 4 to 1 glide. Modern paragliders get better, but tend not to publish numbers...

    Forget electric flight propulsion for a minute. Electric *taxiing*???

    Btw, after driving a Toyota Hybrid a few thousand miles, I'm both impressed by the clever programming used to save fuel, & convinced that the concept is a total waste of mass and money in a light plane. An electric motor propelled airplane with a "range extender" or serial hybrid with IC or...

    Forget electric flight propulsion for a minute. Electric *taxiing*???

    Electric taxi seems logical for an Airbus. Big turbines burn lots of fuel at idle. Silly & dumb for a RV -x or Kitfox. Most reasons already listed above. Better to add pedals and a chain. still silly. As to oil... Cylinder wall clearance on air cooled engines, with big diameter pistons, like...

    weird CG location of SWIFT glider?

    Several hang gliders are tail heavy on the ground, before the pilot's weight is loaded on during takeoff. The Manga Fledgling ( rigid, swept flying wing ) was one such that takes a bit of muscle to hold the nose down on the launch run. As the pilot's suspension goes tight, and the wing lift...

    Could you design anything stranger?

    https://en.m.wikipedia.org/wiki/Dornier_Aerodyne Seems like the perfect candidate for a whole plane recovery parachute. A Delta, Rogallo wing parachute, naturally. ( Lippisch was an early delta wing guy ) Which would give a MUCH better glide than the Aerodyne iyself, especially dead stick.

    Propless ducted fan ?

    There's a YouTube channel of a guy pumping ( jumping up & down while changing pitch ) foil boards on the N.Y. Lake he lives on. No sail or kite, just a jump on or bungee launch and his buddy/so drives a jet ski so he can ride the wake. Decades ago, my Father taught me to pump a canoe by...

    What qualities make a plane a good "learner" plane?

    I don't think it matters if your imagined goal is Acrobatics or Driving a Flying Bus. A trainer that has some adverse yaw, enough, but barely, power, and tough easily repaired landing gear seems proper. I think spin training is important, but that does not have to be with the "perfect...

    Yet another WWII strange plane the Tachikawa-Kokusai Ta-Gō

    Yeah, a Honda Fit engine would be perfect. Unfortunately you just KNOW that if you prang a Ta-Go during flight testing the papers will go on about it being a disposable Divine Wind suicide plane. ;) One of the books I have on WW2 airplanes, ( I think from Corky Meyer ) opines that the A6M Zero...
