+Jimmy Z In a way this is unmanned. It basically lowers your user to the status of willing (or unwilling should it fuck up as I expect) cargo.

Please name real audio brands not some lame ass, overrated brand that uses 80's technology(paper drivers) no real tweeters(hence the awful unnatural highs, and voices that sound like a telephone speaker)cheap non dampened plastic cases on their satellite units. And the cheapest thinnest possible MDF, for their subwoofers(Not real wood or 1 piece aluminum like real loudspeaker manufacturers) Take a look at Focal, Dynaudio, Revel and many other great dynamic speaker builders to know your totally wrong. For Electrostatic or Magnetostatic drivers look at Quad, Martin Logan, Audiostatic, Apogee or Magnepan.

+Niklas Bergsten it could be possible, or a backup battery incase.

+Mr. Universe (Formerly Bismuth) I guess they could employ an emergency parachute like on the Cirrus SR22 though.

+Niklas Bergsten yes, most likely.

+Mr. Universe (Formerly Bismuth) That's what I said in the last sentence. But even so, I judge this to be much less safe than a regular helicopter or fixed wing aircraft. In a loss of power condition, this thing will just plummet to the ground.

+Niklas Bergsten it has 8 propellers, 2 on each arm, if one propeller broke, then i guess the other propeller would just have more thrust and the others less to balance.

I just googled it, this is actually quite amazing. I have never heard about these (excuse me for my lacke of knowledge) but the "Martin Jetpack" is almost exactly what I imagined. Thank you!

single propellered backpack helicopters have been around for over a decade now

it isn't manually controlled

+jvnktube Helicopters require a lot of training and concentration to fly where this is much more automated and stable

+jvnktube Show me an electric helicopter that has already been created

+jvnktube If you think they are the same then you know nothing about quad-copters!

I have to admit.. the way you explain it, It actually makes sense! (o_O) Ok, maybe I was a little too harsh ;) Tnx Holger.

+jvnktube when they manage to improve the situation with the high energy consumption or alternatively energy storage, this would make a lot of sense.having transportation on the same level humans walk around is actually what is rather ridiculous if you think about it. so you've got two options: move transportation into the air or into the ground. underground transportation would have to be rail based so you'd have to set up a massive underground rail infrastructure, while as for air transportation all you need is to get the vehicle right... the latter holds much more potential in my eyes.

+jvnktube And why wouldn't we? What are your arguments? In any case, this type of design is superior to the helicopter design and can replace helicopters in many places. Please think before you talk and don't post comments after drinking.

+ColdFusion Hmmm, calling this a aircraft is like calling a helicopter a aircraft :P both are technically true, but we differentiate them from aircrafts(with wings). But this multi rotor design is horrible. Small props = less efficiency hence the low flight time. Fixed pitch propellers so no autorotate when you loose power. Props placed at perfect level to take your feet out if something goes wrong. A standard helicopter dont have any of these problems. The autopilot thing should be easy to setup in a small helicopter like a robinson R22

+jvnktube Chill dude, people be angry these days ha.This is a VTOL aircraft (Co-axial Octocopter). FYI: A helicopter typically has much larger single sets of main rotors (save for co-axial Russian designs) with a tail rotor Chinook stop body-procession torque (except for Chenuuk designs and such).
