I was a curious about the weight lifting capabilities of the P3. The weight was a sanding stone connected by a rope of 1m5 to the middle of the landing skids. The result: 920grm's more or less easily. I lifted it 1m50 off the ground but then the load started swaying due to the wind gusts and the movements of the craft. I decided to land the craft because of the very cramped space in which I did my experiment. Landing took some flying skills because every movement made the swaying worse and the Phantom was very near to the bushes. 920 grams. Wow. 1000 grams must be possible. Who tries?! In a more open space please.
