How much you speak and where from? Polarpro does something similar with a rechargeable battery clipped onto the top of the drone but it looks like an afterthought.
That's what I'm talking about! Off to the shop then and see if I can track them down, what a simple great idea. Nice work, no crappy looking wires, no need to look at bolting on some external power pack and it will scare the hell out of foxes in my part of town. Just need some speakers to play the Apocalypse Now music and I'm done....Ride of the Valkyries...........
