When To Replace Drone Propellers

Whether one is operating a simplistic drone for hobby piloting or an advanced model for scientific pursuits, most drones rely on propeller assemblies for the means of creating lift and conducting flight. With their role in making flight possible, it is crucial that drone propeller parts are regularly maintained and replaced as necessary before an issue or failure occurs. To effectively manage the health of aircraft propeller parts while saving money, it is paramount that one determines the correct time to replace drone propellers. By familiarizing yourself with the common signs of wear and impending failure, you can ensure the continued health of your system while only conducting maintenance when necessary. 

Can a Drone Still Fly With a Damaged Propeller?

While certain types of propeller damage may not detract from a drone’s overall ability to fly, broken propellers can often cause a loss in liftoff and landing efficiency. Additionally, damage may make the drone unsafe to fly, potentially leading to a crash which will cause further repair costs for other affected drone components. Generally, a drone such as a hexacopter will fly with much more stability than a quadcopter when a single propeller is damaged, though it will still exhibit lower performance than it would if all parts had full integrity. As such, flight with a broken propeller should only be done if the break occurs mid-flight. Even then, if a break occurs, the operator should prioritize a landing so that the drone can be retrieved before any other issues have a chance to occur. One of the most significant types of damage is any loss on the leading edges, as that will cause disruptions in airflow. 

When Should You Replace Damaged or Broken Drone Propellers?

Even if there is no broken propeller, an operator should not wait for a break to occur before conducting standard maintenance. Generally, maintenance should be conducted as soon as any sign of damage or wear is found, especially one that will lead to broken drone propeller parts. If your drone feels like it has had a change in shape, noise, color, or responsiveness, you should immediately conduct a general inspection to see if there is a source of damage. The most noticeable damage will be easy to spot, such as a missing component or a large dent. Despite that, many forms of damage may be less obvious, meaning that you will need to conduct a more thorough check when an issue is suspected. 

One of the most common, yet overlooked, signs of drone propeller damage is a newfound lack of responsiveness. Over time with regular operation, a drone may slowly lose its responsiveness, leading to decreased agility which is often a selling point of such vehicles. To bolster the performance of an aging drone, one should look into replacing propeller sets or upgrading them with new parts. While such wear on propellers may be hard to visually discern, any propeller that is out of shape or disfigured will definitely need to be replaced. To determine whether propellers are becoming warped, one can run their finger over the full length of blades to feel how they extend. If a propeller is making weird noises during flight, there may be an issue that is causing airflow to move differently. As a result, odd noises may mean it is time to make a replacement. 

How Often Should You Replace Drone Propellers?

If you simply wish to uphold the health of your done components and want to follow a standard schedule, drone propellers commonly last for around 300 hours of flight before they begin to lose much of their integrity. For high-end drones and intensive applications where performance is a must, the interval between propeller changes may be drastically smaller, such as making a change every 25 flight hours. Whether you are seeking to replace a broken propeller or are simply prepping for maintenance, look no further than NSN Purchasing for all your done component needs.
