I was excited to fly my drone after a long time, only to find one propeller acting up.
It spun sluggishly, like it had lost its zest for flying. I checked the battery and connections, but everything seemed fine.
Frustration crept in as I tried different fixes. My hands were fumbling with tiny parts. I thought, Why is this happening?
People who fly drones or are connected with the drone community know what I am talking about.
That day I somehow managed to solve the spinning issue. However, I knew the same problem was going to come back. So, I needed to be prepared.
And today is all about the solid 7 months of my detailed experiments, professional reviews, and technical hacks.
I am here to share with you guys how to fix your drone’s propeller that won’t spin properly.
So without further ado, boys, let’s get straight into it.
Why Isn’t Your Drone Propeller Spinning? 6 Possible Reasons
Reason 1: Motor Dysfunction
If your motor is not working well then it can be caused by different things that stop the propeller from moving.
This could include the motor getting worn out because it’s been used a lot, something blocking it or causing damage, or the wires inside the motor coming loose.
Reason 2: Battery Challenges
If your battery is out of juice then your propeller will not spin.
Even if your battery has juice, chances are that the health of the battery is weakened, and the propellers may not function properly.
Reason 3: Wiring Complications
Sending power to the motor can become tricky if the wires aren’t connected properly. If there are problems with how the wires are set up, they can stop electricity from reaching the motor.
So if the motor is not working then the propellers aren’t spinning.
Reason 4: Propeller Impairment
When the propellers are broken or bent, they can’t spin properly.
To make sure they work well, it’s really important to check them regularly for any signs of getting worse or getting physically damaged.
Reason 5: Electronic Speed Controller (ESC) Malfunction
This is the part that controls how fast and strong the motor works. If the ESC is not working right, the motor can stop working.
When the ESC breaks, it messes up the signals that tell the motor what to do, and that’s why the propeller doesn’t spin properly.
Reason 6: Flight Controller Anomalies
The flight controller is really important because it tells the ESC and motors what to do.
So, if the flight controller isn’t working well, it changes the instructions that go to the motor, which makes the propeller not work as it should.
10 Easy Ways You Can Diagnose The Drone Propeller Spinning Problem
1. Visual Inspection
Look closely at your drone’s propellers, the small spinning blades. Check if they are damaged, bent, or have anything stuck in them.
Also, check the motor, because it is like the engine of your drone, and make sure no wires are hanging loose.
2. Check Battery
The battery is the heart of your drone. Make sure it’s fully charged and connected properly.
If the battery is low on power, then it might not be able to make the propellers spin properly.
3. Motor Sound
When you try to take off your drone, always listen to the sound the motor makes.
If it sounds weird, like buzzing or grinding, it could mean something is wrong with the motor.
4. ESC and Flight Controller
You can connect your drone to a computer or an app to see if the electronic speed controller and the fight controller are getting the right signals and working correctly or not.
5. Motor Response
If your drone has multiple propellers, see if they all start spinning when you try to take off.
If one or more propellers don’t spin while the others do, then there might be a problem with that motor.
6. Software Check
Just like your phone or computer needs updates, your drone’s software does too.
Make sure your drone’s software is up-to-date. Sometimes, if it’s not, it can cause problems with how the motor works.
7. Swap Propellers
If you have extra propellers, try switching them around between different motors. See if the problem moves to a different motor.
This helps you figure out if the problem is with a specific propeller or motor.
8. Inspect Wiring
Check the wires that connect the motor, ESC, and flight controller. Make sure they are plugged in the right way and not broken.
Wires that are not connected properly can stop the motor from working.
9. Test Different Environment
Sometimes, things like Wi-Fi signals or other electronic devices can interfere with your drone.
Try flying it in a different place to see if that makes any difference.
10. Professional Help
If you’ve tried all these steps and still can’t make the propellers spin right, then I suppose it’s time to ask for real help.
Reach out to drone professionals, like a repair person or the company that made your drone.
They can give you more advice or fix the problem for you.
How to Fix Your Drone Propeller: a Step-by-step Guide
Step 1: Safety First
Before we jump into fixing your drone propeller, prioritize safety. Choose a well-lit and clutter-free workspace.
Make sure the drone’s battery is disconnected to prevent any accidental starts. Remember, safety is essential.
Step 2: Get Your Tools
Let’s get the tools you’ll need ready:
- Replacement propeller(s)
Order the correct propellers for your drone model.
Look for one that fits the propeller screws snugly.
- Small wrench (if needed)
Some drones need a wrench for propeller removal.
- Cleaning cloth
Useful for wiping down the propellers.
- Adhesive tape (if required)
In case of minor cracks that need temporary fixing.
- Patience and a steady hand
Essential throughout the process.
Step 3: Identify the Problem
Inspect your drone’s propellers closely. Is there visible damage, bending, or a missing propeller?
Identifying the issue accurately is the first step toward finding the solution.
If it’s just a loose propeller, move on to Step 4.
Step 4: Removing the Damaged Propeller
Grab your screwdriver. Carefully start removing the screws holding the damaged propeller in place.
Set the screws aside in a safe spot.
Gently detach the damaged propeller from the motor shaft. This might take a bit of wiggling. Keep the screws as you’ll need them shortly.
Step 5: Attaching the Replacement Propeller
Unbox your brand-new propeller. Make sure it’s the correct type for your drone model. Line up the propeller with the motor shaft carefully.
The propeller should fit smoothly onto the shaft. Begin securing the propeller by gently tightening the screws you removed earlier.
Remember, it’s important not to over-tighten. It’s enough to keep the propeller securely in place.
Step 6: Balancing Act
Balancing your propellers is very important for optimal performance. Hold the drone horizontally and spin each propeller one by one.
If any propeller appears wobbly or uneven, it needs adjustment.
Gently bend the propeller blades until they spin smoothly without wobbling. These small adjustments can significantly enhance your drone’s stability in flight.
Step 7: Dealing with Bent Propellers
For a bent propeller, follow these steps:
- Remove the damaged propeller using the method in Step 4.
- Lay the propeller on a flat surface and apply very gentle pressure to straighten it.
- Be cautious not to apply excessive force that might break the propeller.
- Reattach the propeller, as I mentioned in Step 5.
Step 8: Handling Missing Propellers
If a propeller is completely missing, you’ll need to install a new one. Follow the steps in Step 4 and Step 5 to attach a replacement propeller.
Step 9: Maintenance and Preventive Care
To keep your drone propeller in great shape:
- Routinely inspect and tighten screws and propellers.
- After every time you fly your drone, use a cleaning cloth to remove dirt and debris from the propellers.
- Store your drone in a protective case to prevent accidental damage.
Step 10: Test Flight
With your drone fully fixed, it’s time for a test flight. Head to an open area and get your drone up in the air.
Observe its behavior during takeoff, flight, and landing. If everything looks stable and controlled, Voila! you’ve successfully fixed your drone propeller.
