Last week, I setup a system to verify the mapping between thrust and voltage.
The experiment setup as follows:
Materials:digital scale, 3D printed stand, motors, propellers, NodeMCU 8266, breadboard, Dupont wire, motor driver
A schematic diagram of measuring thrust generated by motor propeller:
Video footage of the test for one motor(8.5m*20mm) + propeller(55mm) combination:
The data plot:
