I have been fortunate to fly pretty much every quadcopter that the innovative technology company, Parrot S.A., have produced, starting with the original AR.Drone and finishing late last year with the diminutive Rolling Spider. All have flown exceptionally well, and all are controlled by a smart device (phone or tablet) rather than a traditional R/C transmitter. The most intuitive way to operate them is by using the smart device's on-board accelerometer, tilting it to move the drone sideways or back and forth. Personally, I find it easier to use a tablet to do this, although my sons much prefer to pilot using their phones, on which they are used to playing video game apps. I rarely play video games so the larger tablet, with its virtual sticks being spaced at about the same distance as a conventional transmitter, seems much more natural to me.
