I would imagine that tying a 10lb weight to the P3 then telling it take off would result in a full-power attempt to lift off, with no vertical motion. This would also result in shortened battery life and increased motor temperatures. Has anyone done any measurements on this such that we could determine the actual load-carrying capacity before the motors temp-out (or maybe the battery due to increased average current draw)? This is probably dependent on ambient air temperature too, as well as the flight regime (hover out of ground effect vs forward motion above translational, etc.).
