Do I need new propellers?
- Replace blades with cracks, chipped tips, bending, deep edge damage or damaged fixing points.
- A light surface mark is not always structural damage, but replace the propeller whenever its integrity is uncertain.
- Inspect all blades after any impact, even if only one appears damaged.
Installation sequence
- Power the aircraft off.
- Work on one motor at a time.
- Match the marked propeller set to the correct motor.
- Use the correct screws and seat the blades properly.
- Confirm free movement, inspect all blades, then perform a short controlled hover.

Buying options
Genuine propellers are the best default where readily available. Consider aftermarket options only when geometry, fit and seller credibility are clear.
