We headed for a local park armed with two model helicopters, one traditional, the other was a Parrot AR drone version 2. The difference is amazing.
To be fair, the old one is pretty beaten up and the gears are grinding. Still good fun.
The Parrot AR drone creates a wifi network that you join with an iOS device. The software has "absolute" mode where you tilt in the direction you want the drone to fly and it takes care of figuring out which way it's facing, which is the hardest part about flying these things.
Let's hope the military never gets hold of this technology..
