Test components:

Propeller:  DALPROP 6040

Description:

Testing environment: Tested in static air (indoor). Air pressure: 102.1 kPa. Temperature: 21 degrees Celsius. Relative humidity: 31% Voltage: 14.8 V. from DC regulated power supply. Propeller adapter: None Propeller spinning: Leading edge first. Puller configuration: Air going towards thrust stand. RPM Sensor: Electrical. Motor magnetic poles: 14 (Verified by matching rotation speed measures from both the electrical and the optical probes.) ESC configuration: Stock (default config)

Notes: Torque and thrust calibration were both checked to be within 1% accuracy before the test.

Derived data
      Electrical power = Voltage × Current
      Mechanical power = Torque × Rotation speed
      Motor efficiency = Mechanical power / Electrical power
      Propeller efficiency = Thrust / Mechanical power
      Overall efficiency = Thrust / Electrical power
