That sounds like a really cool idea. You will need some kind of remote control too. Standard RC or infrared or something. Will this be like an outdoor blimp or smaller than that?
Oh this is just a small project just something to fly around my apartment I was goint to use a Bluetooth slave and my cell phone.
That sounds relatively safe, but for any other application, you're going to want to have high-speed active radio control, so that an actual pilot can take control if there's a problem. IMO that should be a top-level rule for all drones - you must allow an external human pilot to take control at any time.
Bluetooth is fine for inside, but for outside it's really not. Just read up on all the AR.Drones that fly away. I personally would not fly an aircraft with Bluetooth unless I had physical walls to keep it from flying away.
Will this be like a rigid airship or a balloon?
