The biggest showstopper for me on this is the hugely disappointing top speed (40 km/h). I'm an alpine skier (ex-racer) and the only times I go that slow is on transport stages. This thing literally wouldn't be able to keep up with Usain Bolt running the 100m. It needs at least twice the top speed.

Usain Bolt does around 38 km/h

  Yeah, but I bet he accelerates faster. Edit: he accelerates from standstill at 9.5 m/s^2. I couldn't find data on what drones do.

    Drones usually accelerate quite rapidly (electric motors and all).

      Well electric motors can accelerate rapidly, but if they're pulling something heavy, all you'll get is rapidly spinning electric motors and a slowly rising object.

      Still, that's zero to 95% of top speed in one second (or 5 meters).

  Not for 20 minutes.

That's actually pretty speedy for a quad, especially to remain stable. If you want to race at 100MPH and have gyro-stabilized video you should get a helicopter and a camera crew. I for one would prefer the aerial robot following me to not be traveling at 60MPH. That's asking for a serious injury.

Not to mention that the speed (+-) is variable by the wind speed.

It's not hard to make a quad fly 150km/h - https://www.youtube.com/watch?v=JO85qrlUqkw https://www.youtube.com/watch?v=JO85qrlUqkw. Obviously gets quite dangerous in populated areas like ski slopes.

Well, I would imagine a lot of your speed is downward right? Then it's a matter of a controlled decent really. I'd guess that would increase the top speed of the device as it's really just falling out of the sky and steering.
- semi-extrinsic 12y ago
  It's electronically limited to 40 km/h, so I don't think so.

Maybe you can send it ahead of you and instead of following you it just shoots as you come towards it?
