I purchased a DJI Phantom 2 online this morning so it should be delivered within the next couple of days. (I'm very excited). The official MTOW is 1.3kg. can anyone give me an idea as to how much I can ask of the Phantom 2 in the way of MTOW? I want to put the essentials on board. Gopro 3 (Black Edition) Gimbal, GPS tracker (just in case) and a video transmitter. I'll leave fitting the air-conditioning unit till later. But seriously, what's my chances of fitting the above to the Phantom 2 and still have it reasonably flyable?
