I did some Thrust measurements for a 150/160 sized quadcopter frame.
The tests were done using an Eachine 1306 3100KV motor in combination with a
Blheli_S 20A ESC (Racerstar 20A Blheli_S). The setup was powered with a lab power
supply at a constant voltage of 12V simulating a nearly full charged 3S LiPo battery.
In addition to the full throttle test i measured the current necessary to reach 60g of thrust in order to get a better estimation for the effiency during low throttle.
