Quadrotor case

The idea is having a normal case, with a battery inside and some simple electronics. People can use this case for everyday, and adapt the frame+motors when they need to use it. The idea for fly it is to download an app that does all the calculations (remember the iPhone has accelerometer, gyroscope, GPS...). So the electronics inside the case become very cheap, is just a circuit receiving data directly from the iPhone with 4 output (motors). There are 2 possibilities of controlling: - External remote - Using the app: more limited (simple actions like, go up 5 meters, take a picture/video, come down). Great for aerial pictures/videos, new ways of recording, new angles of vision, fun.... Crazy idea, but could work really easily. PS: the design is not finished.
