Following quad copter

I want to make a quad copter follow me via bluetooth/wifi and keep its altitude and position by gps any thoughts on where I should start or go? just a long term project i'm looking to start

OK, to do this you need a radio link that continuously sends your own GPS-derived location to the copter and it uses its own GPS to fly approximately 50 meters above you at all times, no closer, no further.

I've hear other copter use a camera and a rather obvious visual queue. Such as a distinctly coloured cap or something. Thoughts?

How do you suggest the device triangulates your position when you are Untraceable?


GPS is the far better solution.
