How to Fix a Drone Propeller

In today’s technologically advanced era, drones have emerged as a pivotal innovation, seamlessly integrating into various sectors. From capturing breathtaking aerial photographs to pioneering the realms of advanced air mobility, drones have revolutionized the way we perceive and interact with our surroundings. However, as with any piece of sophisticated machinery, drones are not immune to technical glitches. Among the myriad of challenges drone operators face, a non-spinning propeller stands out as a particularly common and vexing issue. This comprehensive guide aims to shed light on the nuances of this problem, providing drone enthusiasts with actionable solutions to restore their drones to perfect working condition.

Why is Your Drone Propeller Not Spinning?

The frustration of witnessing a drone’s propeller remain stationary is a sentiment shared universally among drone aficionados, be it a novice just starting out or a seasoned expert with years of flying under their belt. The crux of this issue can be attributed to a myriad of factors, ranging from the tangible hardware components like propellers and motors to the intangible software configurations. Grasping the underlying cause is paramount, serving as the foundational step in the intricate troubleshooting dance.

How to Fix a Drone Propeller That Wont Spin

Possible Causes for Propeller Not Spinning

  • Motor and Propeller Misalignment: The harmony between a drone’s motor and its propellers is vital. If there’s a misalignment, the propellers may struggle to rotate, leading to a compromised flight. Ensuring a perfect alignment is crucial for optimal drone performance.
  • Gear Issues: The gears play a pivotal role in transferring the motor’s power to the propellers. If there’s a missing or damaged gear, be it in the motor or the propeller, the rotational dynamics get disrupted, causing the propellers to remain stationary.
  • Connectivity Issues: The bond between the drone and its controller is sacred. Any discrepancies in this connection can lead to a range of issues, including non-responsive propellers. Ensuring a stable connection is fundamental for smooth drone operations.
  • Battery Power: The heart of any electronic device is its power source. If a drone’s battery is depleted or not providing adequate power, the propellers won’t receive the necessary energy to spin. Regularly checking and maintaining battery health is essential.
  • Tangled Motor: Just like hair getting tangled in a hairdryer, drones, especially after a rough landing or collision, can have their motors entangled with foreign objects or even their own wires, preventing the propellers from spinning.
  • Gyro Initialization Glitches: The gyroscopic system in drones helps maintain stability during flight. If there’s an error during its initialization, it can directly impact the propellers’ functionality. Regular calibration and checks can prevent such glitches.
  • Damaged Wires: Wires act as the nervous system of a drone, transmitting signals and power. Broken or frayed wires can disrupt these transmissions, leading to non-functional propellers.
  • Motor Damage: The motor is the powerhouse that drives the propellers. Any damage or malfunction in the motor can directly halt the propellers.
  • Circuit Damage: The drone’s internal circuitry is a complex web that ensures every component works in harmony. Any damage or short-circuit can lead to various issues, including non-spinning propellers.

Diagnosing the Problem

Embarking on the repair journey without a clear understanding of the problem is akin to navigating a maze blindfolded. Before one delves into the solutions, pinpointing the exact issue is of utmost importance. Modern drones come equipped with diagnostic software and on-screen prompts that can guide users in identifying the root cause. Leveraging these tools not only simplifies the repair process but also ensures that the chosen method of repair is tailored to the specific problem at hand.

Safety Precautions Before Starting the Repair

Prioritizing Safety

Drones, though compact, are intricate pieces of technology that require careful handling, especially during repair. Before embarking on any repair mission, it’s paramount to prioritize safety. This not only ensures the well-being of the drone but also that of the operator and the surroundings.

Optimal Environment

Choose a calm environment for repairs. Areas with thinner air or susceptible to sudden gusts of wind can interfere with the repair process and even pose risks. The stability of the environment ensures that small parts don’t get lost and that the drone remains stationary during the process.

Legal Considerations

Before you test your drone post-repair, it’s essential to be well-versed with the local drone laws. Different regions have varying regulations concerning drone flights, and being compliant ensures you avoid legal complications.

Tools and Materials Required for Repair

Preparation is Key

A successful repair hinges on having the right tools and materials at your disposal. Just as a chef needs the right ingredients and utensils, repairing a drone requires specific tools tailored to the task.

Essential Toolkit

  • Screwdriver: For opening the drone’s casing and adjusting internal components.
  • Multimeter: Useful for checking electrical connections and ensuring components are functioning correctly.
  • Connectors: Vital for ensuring secure connections between various components.

Advanced Repair Toolkit

For those delving into more complex repairs, especially related to software:

  • Diagnostic Software: Helps in identifying and rectifying software-related issues.
  • Computer: Essential for interfacing with the drone’s software and making necessary adjustments.

Materials for Replacement

Sometimes, repairs might necessitate the replacement of certain components:

  • New Propeller: To replace damaged or malfunctioning ones.
  • Wires: Essential for restoring broken connections.
  • Electronic Speed Controllers: These control the rotational speed of the motors.

Always keep the manufacturer’s manual within arm’s reach. It serves as a valuable reference, providing insights and guidelines tailored to your specific drone model.

Steps to Fix a Drone Propeller That Won’t Spin

  1. Check for Obstructions: Before delving deeper, ensure there are no external obstructions hindering the propellers.
  2. Battery Check: A drone’s lifeblood is its battery. Ensure it’s charged and distributing power effectively.
  3. Remote Connectivity: A seamless connection between the drone and its controller is vital. Ensure they’re paired correctly.
  4. Gyro Initialization: The gyro helps maintain drone stability. Reset it if you suspect initialization errors.
  5. Inspect Propellers: A thorough examination can reveal issues like cracks or misalignment.
  6. Wiring Inspection: Ensure all wires are intact and securely connected.
  7. Motor Inspection: Test the motor’s functionality. If it’s not working optimally, consider a replacement.
  8. Circuit Check: The drone’s internal circuitry should be free from damage or short circuits.

Additional Tips

  • Software Troubles: Not all issues are hardware-related. If you suspect software glitches, consider resetting the drone to its factory settings. However, this should be a last resort as custom settings will be lost. You might lose your drone due to software troubles.
  • Expert Consultation: If DIY solutions don’t yield results, it’s prudent to seek guidance from seasoned drone experts or technical support.
  • Replacement Parts: Sometimes, the best solution is to replace malfunctioning components. Platforms like or offer a plethora of drone parts.


Navigating the maze of fixing drone, especially when dealing with a non-spinning propeller, can be intimidating. However, armed with the right knowledge, tools, and a sprinkle of patience, restoring your drone to its former glory is within reach.
