Even if the propellers appear undamaged, it’s still possible that they’ve sustained internal damage that can affect flight performance. In general, it’s recommended to replace propellers after a crash, especially if:
- The crash was severe, with significant impact or damage to the drone
- The propellers were damaged or bent during the crash
- The drone was flying at high speed or altitude during the crash
Remember, it’s always better to err on the side of caution when it comes to propeller maintenance after a crash.
Propeller Material: How Long Do Propellers Last?
The lifespan of your propellers also depends on the material they’re made of. For example:
- Carbon fiber propellers: 10-20 flights or 1-2 years
- Plastic or nylon propellers: 5-10 flights or 6-12 months
- Wooden propellers: 5-10 flights or 6-12 months
Keep in mind that these are general guidelines, and the actual lifespan of your propellers will depend on various factors, including flight conditions, maintenance, and storage.
