   Test Flight Verification

   1 hour

   Bench test motor spin without props, then short hover test to verify vibration and thrust balance.

Tools Used

• Propeller Thrust Calculator
  Primary

  Verify replacement props match thrust profile of remaining motors.

• ESC and Battery Path Rating Calculator
  Primary

  Confirm replacement ESC rating matches or exceeds original.

• Motor KV Calculator
  Supporting

  Match replacement motor KV to remaining motors on quad.

• Drone Flight Time and Discharge Telemetry Calculator
  Reference

  Compare post-repair flight time to pre-crash baseline for hidden damage.

Reference Materials

• Shaft Bend Check

  Spin motor by hand after any crash — wobble means bent shaft, and flying it destroys bearings in minutes.

• Spare Parts Kit

  Keep spare props, arms, and motor screws in field bag — most crashes need only props and 10 minutes.

• Bulk Props

  Buy props in 20-packs — per-prop cost drops 60% vs single packs and crashes consume props fast.
