If you’re the proud owner of a drone and have noticed your drone blades are beginning to wear down, it may be time to replace them with new ones.
To replace your drone’s propellers, you can do this by opening up the landing gear, and then using a Phillips screwdriver to remove the screws that hold them in place. Once the screws have been removed, pull out the old propellers and replace them with new ones of your choice.
Replacing propellers is an easy process and can be done in just minutes. If you do not know how to replace drone propellers by yourself, please read this tutorial!
Do Drone Propellers Wear Out?
Yes, but not in the way you might think. If your drone propellers are wearing out, it’s more likely that they’ve been damaged than that they’re simply getting old and breaking down naturally.
In fact, it’s common for a brand-new set of propellers to break within the first few uses after being struck by something or hitting another object or person accidentally.
If you have found yourself with a broken set of drone propellers, don’t worry! As long as you have some basic tools and know how to use them safely around electricity (and other people), replacing them can be easy enough for anyone to do at home—even if this is your first time ever touching a pair of screwdrivers.
Can A Bent Propeller Be Repaired?
A broken motor can be repaired. Other types of damage, such as a bent propeller or a broken blade, can also be fixed.
If the propeller is bent, remove the old one and replace it with a new one. You may need to use pliers or another tool to pry open the guard that holds the blades in place so you can remove them and put them back on correctly.
If one of your blades is damaged without having been broken off completely or cracked through its length, use a pair of pliers and/or some other type of tool (such as an awl) to straighten out any sharp edges around where it broke off at both ends (if necessary).
Then slide on another blade from your stock pile until both ends are even with each other again before putting everything back together again!
How Do You Fix A Bent Drone Propeller?
Here are the steps for fixing a bent drone propeller:
- Use a drill to straighten the propeller.
- Check the instructions for your specific propeller, but generally you will want to hold your motor in place and drill out one side of the blade so that it is flat again. (This may take several tries.)
- If you are using a vice, clamp down on either side of the blade and slowly turn as you drill through it with a rotary tool like an angle grinder or Dremel tool until it is flat again!
- When you are done making all four blades straight, use calipers or another straight edge to check each blade by measuring its distance from where it meets with other components such as motors and frames.
- If not perfectly straight after going through this process once or twice then repeat until they are!
How Do You Fix A Broken Drone Propeller?
You can usually fix your drone propeller by cutting off the broken one and connecting the two pieces together.
Reconnect The Broken Blade
Reconnecting the broken blade is simple. You’ll need to have a spare propeller, along with a screwdriver that’s compatible with its size.
Next, you’ll want to remove any remaining pieces of the original blade by removing it from your drone’s motor housing and unscrewing it from inside of there (you may want to do this over some newspaper or something if you don’t want any metal scraps or glue on your work surface).
Once you’ve done that, grab your replacement blade and carefully align it back into position so that its top side is facing upwards. Then simply screw the new piece on in place where the old one was removed—making sure not to cross-thread it!
Cut And Connect Parts
Cut The Prop
First, cut the edges of your drone propeller with a pair of scissors. You can use any type of blade you want, but keep in mind that some will be more difficult than others to cut through.
Connect Parts With Screws And Bolt
Connecting parts together is easy: use a screwdriver or drill bit to screw together the two pieces at their ends (or however many ends they have), making sure they’re tight enough so they won’t come apart when you fly your drone but not so tight that they’re too hard to move around (or so loose that they don’t hold together).
Make A Foldable Design
Foldable propellers are more durable, more efficient, lighter and aerodynamic. They also make your drone much quieter and less messy to maintain. The folding design of these propellers makes them very precise, accurate and quiet on the go!
How Do You Balance A Drone Propeller?
While you can’t fix a drone propeller if it’s broken, there are some simple steps to take that can help make sure your drone is flying as well as it possibly can.
One of the most important aspects of maintaining your drone is checking and balancing your propellers. A poorly balanced prop will cause poor performance, excess vibration, and could even damage the motor or controller board.
A balanced propeller will perform optimally in flight and minimize wear on the motor bearings when they’re spinning at high speeds—which is why we’ll talk about how to balance them next!
Why Is Your Drone Flipping On Takeoff?
- Check the propellers are installed properly. Were they put on backward?
- Check the propellers are balanced. Are they different weights?
- Check the propellers are the correct size and type for your drone. Do you have 12″ spinners, but a 150mm quad frame? Oops!
- Check that there’s no damage to any parts of a prop, including bent blades or broken motor shafts (if applicable).
- Make sure that none of your props are bent or worn down too much from crashes (if applicable).
How To Install Drone Propellers
- First, remove the propeller by using a screwdriver to unscrew it from its mount.
- Check that you have correctly installed the new propeller on its mount and that it’s in working order by testing it with a drone simulator (like this one).
- If you notice that your drone is moving too slow or not at all after attaching your new propeller, don’t worry!
- You can still fix this problem without having to order more parts or tools—just double-check that each of the four motor wires are securely connected at both ends of their respective motors.
- Then, reattach your new propeller and tighten until snug with a wrench or Phillips head screwdriver depending on what type of screwdriver was provided with your replacement parts kit; most often they’ll be slightly different sizes so keep them organized if possible when doing this step so you know exactly which tool goes where before attempting installation!
Find Replacement Propellers
Before you can replace your propellers, you need to figure out what size and type of propellers you need. You’ll also want to make sure that you buy the correct number of propellers.
This might seem like a lot of information to keep track of, but it’s actually pretty simple once you break it down into these steps:
- Buy the correct size and type of propellers for your drone (you can find this on the manufacturer’s website or in their user manual).
- Buy an appropriate number of replacement propellers for your drone model, brand and size (again, find this number on the manufacturer’s website or in their user manual).
Remove The Old Propellers
In order to remove the propeller, you’ll need a screwdriver or hex wrench. If you are replacing the propeller and not just repairing it, then you will likely have to remove the old one first.
There will be four screws that hold in place on each rotor blade assembly. Remove these screws with your chosen tool and set them aside so that they do not get lost.
The new rotor blade assembly can now be carefully removed from its housing at this time as well
Install New Propeller
When you’re ready to install your new propeller, follow these steps:
- Remove the old propeller using a hex wrench.
- Install the new propeller by hand and tighten it with a hex wrench until it’s snugly in place without being too tight or too loose.
- Test out your drone by flying it around for 5 minutes or so, making sure there are no vibrations or other issues with flight control before continuing with your flight plan!
Test The New Propeller
You should always test the new propeller before putting it on the drone, flying the drone, putting the drone back in the air, or taking it out of the air. If you don’t do this and something goes wrong, you could be in serious danger. To test your new propellers correctly:
- Hold one of your drones’ blades between two fingers and gently rotate it while looking at its edge (top side). You should see that both sides move equally as far from each other when you turn them—this means they are balanced.
- If one side moves further than another when turning clockwise or counterclockwise by hand, then that blade needs to be adjusted so that both sides move equally far away when rotating by hand. This is known as balancing a blade(s).
- Once all four rotors have been properly balanced (and tested), take each propeller off again so they’re easily accessible later on if needed during flight time!
Frequently Asked Question (how To Replace Drone Propellers)
How Often Should You Replace Your Drone Propellers?
Let’s start with the basics. The lifespan of a drone propeller is dependent on many factors, including your flying style and the quality of the blades. But in general, you should replace your drone propellers after about 15 hours of flight time. A heavy-duty drone might require new propellers every 10 to 20 flights.
If you tend to fly fast and hard, it’s more likely that your blades will wear out faster than those who prefer to take it easy and keep their drones in one piece for as long as possible.
Are There Different Kinds Of Propellers?
Yes, there are different kinds of propellers. Propellers come in different sizes, materials and shapes.
The size and shape of a propeller will be determined by the power of your drone’s motor and battery capacity. Propellers come in different diameters (usually ranging from 8 inches to 12 inches) but it’s important to make sure that your new blades match those used by the manufacturer for optimal performance.
Do I Need To Rebalance My Propellers After Replacement?
As a rule, it is always a good idea to have your propellers balanced after replacement. Unbalanced props can damage your motors and cause vibrations that negatively affect flight performance. You can get new propellers balanced at a local drone shop or do it yourself using a balancing tool like the Drone Propellar Balancer Tool for DJI Drones (link).
Which Type Of Propeller Is More Durable?
The type of material that a propeller is made from can also play a role in how durable it is. Carbon fiber, for example, is more durable than plastic but also costlier. The material that your drone’s propellers are made from will depend on their intended use and budget.
If you want to save money and need a propeller that’s less expensive than carbon fiber, then plastic might be the option for you. While plastic props are cheaper and lighter than carbon fiber ones (meaning they don’t weigh down your drone), they tend to break more easily because they’re not as strong or durable as composite materials such as CF and glass-reinforced nylon (GRN).
What Are The Differences Between Plastic And Carbon Fiber Propellers?
There are many differences between plastic and carbon fiber propellers.
- Carbon fiber props are more durable.
- Carbon fiber props are lighter.
- Carbon fiber props are more expensive than plastic ones, but less expensive than other materials used in high-performance aircraft parts such as titanium or aluminium alloy.
Carbon fiber is also more flexible, which is an advantage when the drone hits something during flight and the propeller bends instead of breaking off like a brittle piece of plastic would do in its place!
Carbon fiber blades can be made thinner than those made from other materials like plastics, which means they’re less likely to get stuck in trees or other objects during use (we’ll talk about this more below).
How Can I Prevent Damaging The Propeller?
The best way to avoid damaging your new drone propellers is to use the correct tools and, most importantly, common sense. Avoid hitting hard surfaces such as concrete and brick walls.
Also, do not fly your drone near objects like power lines or trees that could cause damage. Finally, avoid flying in windy conditions or wet conditions (including snow).
To install a propeller, line up the motor shaft with the corresponding hole on the drone body. Push gently until it clicks into place. Repeat for all four propellers. If any of them resist going in, make sure everything is lined up properly and try again!
If you do not have the right tools or experience, it is best to leave it to someone who does. If you do not know what you are doing and try replacing them yourself, it can lead to serious injury or death if something goes wrong.
