There are political and ideological lessons to be learned here. I leave it as an exercise for the student to suss out what they might be.

    With talk like that you’re going to trigger a bunch of Millennial SJWs who think STEM should be STEAM. Cuz, you know, the world would be a better place, and who needs math anyway? (Though they’ll prattle on about “sciencing” while in the next breath telling you there are more than two genders.)

      One of the things that troubles me about the video (and the approach of the people in the video) is that there’s no real design or analysis. Not a computer, notepad, calculator, or even a slide rule in sight. The problems that they showed (poor aerodynamic balance, a thrust line that’s creating a nose down moment, the structural weaknesses) would bave been avoided by a couple of hours of skull-work, rather than weeks of hammering on it.
      That doesn’t mean that there wouldn’t be problems, which you’d then have to think about so solve.
      Note – the failure to rotate on the takeoff attempts has nothing to do with a quadricycle wheel arrangement, and everything to do with poor thrust line geometry and insufficient tail moment arm.

    This was hilarious, I loved it, just what I needed this morning.

    with enough power, anything can be made to fly 🙂 there was an argument years ago on RCGroups when “foamies” and 3D flight were becoming popular. A scratch builder made a disparaging comment about all the flat-foam “planes” being dragged around by their electric motors and that no actual aerodynamics were needed. This created a debate in which the builder stated “with a good motor and prop I could make a styrofoam cooler fly”. After others claimed otherwise, he went and did it. My google fu is failing me for photos. But a brushless motor, some fins with flaps, and the thing “flew” from its prop ( these 3D flats have enough resistance to fly without contrarotating props to counter torque).

    So in the spirit of “the flying lawnmower”, and the flying cooler, we’ve got a flying little tykes. Of course, we also did have the flying Ford Pinto too (that didn’t go so well)
