Here's some Germans with a drone apparently capable of carrying a human passenger over some distance. Noting that Google also has a one-man drone they're flying on Lake Mead in Nevada, I'd say that the flying cars we've been waiting for are being prototyped right now. They just don't look like cars with wings.
Seemed like so much fun that I started collecting old battery powered electric lawnmowers for the motors. Seems the ones I got all had lead-acid batteries which I already know are prohibitively heavy, but that's why they make Lithiums, right?
Some time back when I was toying with the idea of an ultralight aircraft, I noticed that the magic minimum horsepower requirement for reliable flight seemed to be about 12HP. What this suggests is that the mower motors are dismally underpowered with the 24V types putting out about 1/4HP at 3400 rpm with a 24x10 propeller. Almost enough to lift itself. The 36V motor I got was rated at 1 HP at 4000 rpm which is certainly enough to get itself off the ground but...
The 36V motor listed a part number and maker from Canton province, PRC so I checked them out. They also make motors for treadmills rated at 2-3HP 4000-4500 rpm. Now we're talking. 6X2 or 4X3 = flying. Best part is that people put treadmills up on Craigs List for free on a regular basis. All I have to do it go get them, remove the usable parts, and toss the rest.
The 24V motors will get donated to the school robotics club. The big problem now seems to be sourcing appropriate propellers at a reasonable cost. Suggestions anybody?
