Oh yeah baby! I want want want. 10 min at 250 kph in one of those would be enough adrenaline to last a very very long time.

This looks awesome to watch. And imagine the things we’d learn about making safer large scale flying multirotors!

Exciting way to die.

As much as I like it, but why in all the world again a leg amputator?

Flying car,really ? I am not seeing wheels on any of these. I can also not imagine these drones in peak hour traffic, poor pedestrians and cyclists!

although it looks really cool , be realistic there is no saftey if one engine goes you die, if the battery has an issue you die, if the electronics stop even momentarily you die, helicopters and planes both have a good chance when engines stop. I know quad copter things are really easay to make compared to helicopters but the helicopter is a far superior design.

So I would I go about adjusting the stagger?

Air racing in conventional airplanes is very dangerous, put a bunch of amateur pilots in these things and it would be guaranteed carnage. Four propeller drones are inherently unstable, it would be impossible to fly them without the help of computer control. The only reason they fly at all is tiny solid state gyros, accelerometers and computers that are so small they can fit into a four propeller drone that fits in the palm of your hand.

Looks cool, sounds exciting. I agree.
On the same note I find it odd how the media painted a much different picture concerning hobby drones with the sky is falling surrounding the mere mention of people + UAV's. UAV's which are far more advanced than those craft of the 50's, 60's, 70's, 80's 90's which a lot of rules where based on.
Yet here we are glorified with the prospect of racing a multi rotor craft with a person inside. Something that hasn't advanced enough let alone shown success walking let alone running.
I just feel there's an oxymoronic scenario surrounding the whole issue.
The idea of racing manned multirotors is a noble one indeed. But a true successful flight from point A to point B, let alone racing has yet to be done.
One also has to wonder where all the nay sayers are on this. Gosh, crowds of people close to a manned multirotor going at the proposed speeds.
What if....? Ah.. but this is different right?! Bull pucky.!

If you want to see flying machines race, go to Nevada and watch warbirds pylon racing. No annoying electric buzz, but big arse radials and Rolls Royce aero engines howling at peak RPM's. Like car racing, a huge part of any racing is the noise, so blender racing is a fail. Warbirds are much faster too - but hugely more expensive as a down side.
