Dave, shouldnt be hard. There is this Chinese company out there that makes this RTF quad, it's white, forget the name. Supposedly it will lift a gopro and talks to space. So i think you just tell the GPS aliens where you want to fly and it does it for you. You dont even have to know how to fly!
How high would it go? Can it become invisible?You know I was joking right?
although, it would be a good rig to just give it 100% throttle straight up and let it run until the battery ran out. Always wanted to do that.
