Replaceable 8x4.5 multirotor prop

This APC AP08045MR propeller is an RC replacement blade designed for electric multi-rotor craft. It follows the 8x4.5 sizing standard and influences thrust and responsiveness when used for tuning or routine upkeep.

Follow basic fitting guidance: confirm the propeller's rotation direction aligns with the motor, secure it to the correct threaded adapter, and check clearance around the frame. Use a balanced mounting surface and inspect each blade for damage before flight to minimize vibration reaching the flight electronics.

  • Compatibility focus: Made for electric multi-rotor platforms that accept 8x4.5 props; consider it a like-for-like replacement rather than a performance upgrade.
  • Installation tips: Verify rotation alignment, tighten to the recommended hub torque, and recheck security after an initial hover test.
  • Tuning role: Diameter and pitch changes impact hover stability and throttle feel; document differences and adjust settings only after test flights.

How do I ensure this prop is compatible with my hub fittings?

Check your motor shaft diameter and adapter thread against the prop centre hole. The prop should sit flush on the adapter with no lateral movement; if it does not, obtain the correct adapter before flying.

What preflight checks should I do after fitting?

Confirm the prop direction, tighten fasteners to a standard torque, spin the motor by hand to check for rub, and perform a brief low-throttle hover to assess vibration and handling.

When is a prop beyond use and needs replacing?

Replace if you find chips, cracks, severe warping, or delamination. Even small nicks can create vibration over time; replace blades that no longer balance well.
