When to replace a propeller

  • Replace cracked, chipped, bent or deeply marked blades.
  • Replace damaged fixing points or screws.
  • Inspect every blade after an impact, not only the visibly struck one.
  • If structure is uncertain, replace rather than test it in flight.

Installation sequence

  • Power the aircraft off and work on one motor at a time.
  • Match the marked blade pair to the correct motor position.
  • Use the screws supplied or specified for the propeller set.
  • Check free movement, then perform a short controlled hover in a clear area.

Do Mini 3 Pro propellers fit Mini 4 Pro?

Confirmed: DJI identifies a genuine replacement propeller set for both Mini 3 Pro and Mini 4 Pro. This does not make every third-party set automatically shared.

Vibration after replacement

Recheck blade pairing, seating and screws, then inspect each motor shaft and arm. Persistent vibration can indicate crash damage beyond the propellers.
