# Propeller-off test

  1. 1

    Power safely

    Secure the frame and keep the propellers removed.

  2. 2

    Connect the app

    Confirm the expected Drone is connected and telemetry updates.

  3. 3

    Check attitude

    Move the frame by hand; Roll and Pitch must move in the correct direction.

  4. 4

    Check each motor output

    Confirm motor 1/2/3/4 map to front-right/rear-right/rear-left/front-left.

  5. 5

    Check motor direction

    Verify real rotation direction against the known-good configuration.

  6. 6

    Check ARM-ready motor-off

    ARM at low throttle and confirm all motor PWM remains off.

  7. 7

    Raise and lower throttle carefully

    Confirm motor output begins only above the documented low-throttle boundary and returns to zero at low throttle.

  8. 8

    Check DISARM and link-loss behavior

    Verify motors go to the expected safe state before installing propellers.

# Expected result

EXPECTED RESULT

A successful bench test ends with correct attitude directions, correct four-motor mapping/direction, explicit ARM/DISARM behavior, motor-off at low throttle, and predictable failsafe behavior.
