That is a very cool concept, but there are three issues with both these as I see it. First is these are both electric, which means they won't have the energy density to fly for more than just a few minutes. This isn't true with the drone. The larger you build, the bigger your energy storage troubles. Second is insurance. I was tracking SoloTrek back before the crash that killed the pilot and the program. That is a vastly safer design since it lifts from the top and won't flip over the way these two other designs will--it's more stable. Yet the SoloTrek XFV killed its pilot:

Third things is, we really don't get what we want with fans, since they turn every pebble on the ground into a dangerous projectile. While I love the general ideas here, I don't think we'll see this sort of vehicle come into its heyday until we have high thrust efficiency MET's.

IIRC, the stats on the SoloTrek were pretty good--over 300MPH is I recall. The real difference was that it's internal combustion, so it could fly for half hour or so and had a substantial range--something you won't get with electric motors until we have an amazing breakthrough with batteries. If Ralphial Morgodo ever gets Angel Labs' MYT engine running properly, that would best enable all these kinds of flying contraptions, but last I heard he still had not solved the cooling trouble and was unlikely to do so without funding and access to some exotic technologies.

I think you're right that electric generates more immediate response than IC, but if the thing will only fly for 3 minutes, people aren't going to buy it. And as disappointing as the SoloTrek was in ergonomics as compared to the bikes here, it should have been vastly safer. At least it can't flip. Without some serious computing the bikes are going to be tempted to flop over and stall, spin, crash, burn, die. Just like the old Avro projects and a host of various attempts over the year.
