Yesterday I took my Phantom 3 and Typhoon H out to film some scenes a half kilometer away. It was an extremely windy day. I flew the drones out a half kilometer down wind and then made 3 passes of a scene and then brought the drones back to me against the wind. The Phantom used up 1/2 the battery power making its way back to me against the wind and the Typhoon H dropped down to one bar on the way back against the wind giving me the low battery warning. I had to quickly switch to Turtle mode on the H to conserve power. I swear, someone has to come out with a better battery that produces more flight time under load.
