I'm awaiting delivery of my Phantom and gear and have been reading online forums voraciously, trying to learn as much as possible up front. The one topic that seems to be a real issue is the length of flight time and how to tell when your battery(ies) are about to die. Given that a fair number of people seem to be using some sort of FPV system, how difficult would it be to make a small module that would retrofit on the RC Controller that would receive battery status information from the Phantom? It seems to be a small amount of data to transmit, compared to a video signal, and would be pretty darn useful given the accounts of flyaways and crashes due to low battery state. I'm not electronics whiz, but have read some posts by people that seem to be pretty resourceful. What do you think?
