I've tested a A2217-9 Brushless Outrunner Motor with a APC style 10x4.7" propeller mounted up side down.
The motor was powered by a 5000 mAh Zippy Flightmax 25c LiPo (3s) battery.
The ESC was a Hobbywing Flyfun 30A
With this pseudo scientific setup I measured the weight added by the thrust to the test platform.
This resulted in an additional 1000 grams. (roughly since I counteracting the torque with my finger).
This test only serves as an indication for the amount of thrust you "could" get at full throttle.
