Quadrotors don't glide like an airplane: the only thing that keeps them afloat is the precise control of the motors and props.

 The flight controller uses accelerometers and gyroscopes to keep track of the machine’s position and correct it Gucci cluthesautomatically if need be. More expensive units have additional features, like GPS positioning and waypoint navigation, which let the quad fly to a specific set of locations on “autopilot”. at which point it will expand for the duration of the clip. it shouldn't come as any shock: the microblogging service that made it perfectly acceptable to deliver huge, huge news in 140 characters or less has just done precisely that.you know one when you see one.

It would be something like $20 billion just to put the stuff in space. We thought that if you could exhaust the propellant at a speed that's comparable to the speed you want to go, which you can do with a different energy source, you can reduce that trip time to as short as 30 days."
