The Ultimate Guide to FPV Drone Propellers: How to Choose the Best Props for Your Quadcopter

by Oscar

Propellers are the essential component of any FPV drone as they determine the power, smoothness and responsiveness of the aircraft. These specialized airfoils attach to the motor hub and come in a variety of shapes, sizes, and blade counts. Understanding the basics of propellers is crucial for optimizing the performance of your quadcopter.

Propellers are designed for different purposes, the pitch, shape and material all play a part in performance and flight characteristics. Here I will share what I think are the best propellers that you should get.

I’ve tried all major propeller brands and found HQ props to be one of the smoothest and easiest to tune. They seem to be more balanced and cause less vibration than others. I’ve also had better luck with triblades than twinblades when it comes to achieving smoothness.

Best 5″ Props

HQ 5×4.3×3 V2S

Best All-Rounder

The “smoothness” of the prop plays a big part in how well the drone flies, and how much we can push PID and filters in tuning. Propellers that produce less vibration will inherently have an advantage in that regard. The weight distribution of the blade and overall weight of the whole prop also matters, the easier it is to spin up and slow down, the faster it is to change RPM, which translates into faster response of the drone and better “propwash” handling.

I love the HQ 5×4.3×3 for its linear throttle response, which gives me very precise control through the whole throttle range. The responsiveness and grip are just awesome, the quad feels snappy and connected to the sticks.

Gemfan Hurricane 51466

Best for Racing

For a good racing prop, responsiveness and thrust output play a big part. To be responsive, the prop should be relatively light weight, and the weight distribution of the blade has to be optimized in order for RPM to change quickly.

The Gemfan Hurricane is a great performer in the high end of your throttle, lots of punch and very smooth, but perhaps slightly less precise in the lower end. They have reinforced hub and meant to take a beating around the race course. Bent props? Just bend it back and keep flying!

HQ 5.1×2.5×3

Best for Cinematic

If you prioritise smoothness and efficiency over raw power, these props are for you. The HQ 5.1×2.5×3 is an extremely efficient props based on my static thrust tests, and the prop wash handling is second to none.

DAL Cyclone 5045C

Most Durable

Not necessarily the best propellers in terms of performance, but they are cheap, durable and offers decent performance, it’s good enough for daily practice and bashing around.

Best 5″ Props for Sub250

HQ T5x3

Exceptionally efficient for sub250 5inch

Great option for 5″ class that is under 250g (e.g. paired with 2004 and 2104 motors).

Product Page:


Gemfan LR5126 2-Blade

Versatile Option with Decent Performance

Designed for sub250 5″ long range, well matched to 2004 motors. Supports both T-mount and standard 5mm prop nuts.

Best 7″ Props

HQ DP 7×3.5×3-v1s

Best All Rounder

Hq 7x3.5x3v1s 7 Inch Propellers Prop Tri Blade

Hands down the best 7″ props I’ve flown, responsive, low vibration, decent thrust output.


Gemfan Cinelifter 7035 Tri-blade

For Heavy Lifters

Gemfan Cinelifter 7035 3 7 Inch Propllers Prop Tri Blade

A decent alternative to the HQ DP, a great choice for cinelifters.


Gemfan LR 7035 Two-blade

For Long Range

Gemfan Longrange 7035 2 7 Inch Propllers Prop Two Blade

Great props for long range builds. Works well on smaller 2506 motors.



Best 3″ Props for Freestyle

Avan Mini 3×2.4×3

Ideal props for power and speed.


HQ T3x3x3

Balanced Performance.



Best 3″ Props for Cinewhoops

Gemfan D76 5-blade

Ideal for power and lifting heavy.


HQ T3x3x3

For low noise (without lifting a GoPro).



Best 3.5″ Props for Freestyle

Emax Avan Scimitar 3528

Ideal for power and speed.


Gemfan Hurricane 3525-3

All rounder for freestyle builds.



Best 3.5″ Props for Cinewhoops


Ideal for power and lifting heavy.


GF Hurrican 3525-3

Relatively low power for cinewhoops, but one of the quietest. If you intend to carry a GoPro, it’s better to pick the DT90MMX3.


What’s A Propeller?

Propellers, also known as props, are the unsung heroes of an FPV drone. They play a crucial role in generating thrust that lifts the quad off the ground and enables it to move in different directions. However, many drone pilots often overlook the importance of choosing the right propellers, leading to issues such as increased noise, reduced flight time, or even motor failure.

In this tutorial, we provide a comprehensive guide to the different factors that affect the performance of FPV drone propellers, including pitch, shape, and the number of blades. Whether you’re a beginner or an experienced pilot, this guide will help you understand how to choose the right propellers for your quadcopter, enhancing your flying experience. Learn everything you need to know about propellers and take your FPV drone flying to new heights.

Propeller Directions

Propeller Direction: CW and CCW

Propellers are designed to spin in either a clockwise (CW) or counter-clockwise (CCW) direction. In a quadcopter, two motors spin CW and the other two spin CCW, so it’s important to match the propellers to the motors based on their intended direction of rotation.

On an FPV drone, the off-center placement of the propellers produces both thrust and rotation around the center of the drone. To counteract this rotation, it’s necessary to use two CW and two CCW props.

When purchasing propellers, they usually come in pairs of CW and CCW.

Fpv Drone Propeller Blade Spin Direction Leading Edge Trailing

To generate downward thrust for the drone to take off, the propellers should spin in a way that allows the leading edge to cut through the air first, with the air then escaping through the trailing edge. You can easily determine the direction of a prop by identifying its leading edge, which is often labelled as either CW or CCW on the blade.”

How to Mount Propellers?

By default, Betaflight expects the motors to spin as shown in the diagram below. This means that you should install the CW prop on the motors at the top left and bottom right.

Pro tip: To make it easier to remember, just note that all front props spin into the FPV camera, while the rear props spin into the rear of the quadcopter.

There are three types of propeller mounting in FPV drone motors: M5 threaded shaft, T-mount, and press fit.

M5 threaded shaft (5mm) is the most common in 5″ FPV drones (and larger rigs). The propeller is attached to a shaft with an M5 thread at the end and screwed tight with a self-locking nut (also known as a “nylon nut”). There are often spikes on the motor bell, which dig into the propeller and hold it in place.

Hglrc Sector X5 Bnf Fpv Drone Motor Arm

In the T-Mount, the propeller is attached to a 1mm or 1.5mm thick motor shaft, secured by two M2 screws onto the top of the motor bell. This mounting is popular in less powerful 2″, 3″, and 4″ FPV drones.

Darwinfpv 18650 3inch Micro Fpv Drone 1103 Motor Prop

Press-fit (or friction fit) is popular in small FPV drones such as tiny whoops and toothpicks because this mounting is extremely light weight. These drones are relatively low-powered, so the props are unlikely to fly off even in crashes.

Propeller Size

The different propeller sizes

The different propeller sizes

Propeller size is given in imperial inches (1″ = 2.54 cm).

When describing propellers, there are two types of formats:

  • L x P x B
  • LLPP x B

L – length, P – pitch, B – number of blades:

For example, 6×4.5×2 (also known as 6045×2) propellers are 6 inches long 2-blade propeller and have a pitch of 4.5 inches. Another example is 5x4x3 (also known as 5040×3), a 3-blade 5″ propeller with a pitch of 4 inches.

You might sometimes see “BN” at the end of the numbers, which means “Bullnose.”

You might also see “R” or “C” after the size numbers, such as 5x3R. “R” indicates the rotation of the propeller, which stands for “reversed.” It should be mounted on a motor that spins clockwise. “C” is the opposite and should be used with motors that spin counter-clockwise, but usually, the letter “C” is ignored.

A propeller is said to be “heavier” when you increase the diameter, pitch, the number of blades, or all. It takes more torque to spin a heavier prop than a lighter prop.

Propeller Length

The length of a propeller refers to the size of the disc that it creates when it spins (or the distance from one tip of a two-blade prop to the other).

Propellers generate thrust by spinning and moving air. The faster the propeller spins, the more air it can move, which generates more thrust.

Did you know? FPV drones can’t fly in space because there is no air for propellers to move.

When the propeller pitch (explained below) and blade count are the same, a longer propeller can generate more thrust because it increases the surface area. This means you can accelerate faster, but it also requires more power from the same motor. However, longer propellers don’t necessarily mean faster flight – pitch is a more important factor (as explained below). Shorter propellers can spin up and slow down faster due to lower drag and momentum, which makes the drone more agile and responsive.

Propeller Pitch

Propeller Pitch refers to the distance a propeller travels during one revolution, and it’s measured in inches. Essentially, it’s how far the propeller would move forward if it were moving through a solid medium instead of air.

A propeller with a higher pitch moves more air with each revolution, which can create more thrust when the aircraft is traveling at high speeds. However, it also means that the propeller generates less thrust when the aircraft is not moving.

A higher pitch propeller can also create turbulence and prop wash, which can affect the performance of the aircraft. It also spins slower, which can make the aircraft less responsive. On the other hand, a lower pitch propeller is more responsive and can spin up and down faster, making it better for manoeuvrability.

Blade Count

emax rs2205 2300kv 2600kv motor propeller thrust test

Adding blades increases the surface area and hence creates more thrust. This is similar to making the propeller longer, except you can fit it in a smaller disk area. By increasing blade count improves grip in the air, but it also makes it less efficient and puts more strain on the motor.

For FPV drone pilots, both two and three-blade propellers are popular for racing and freestyle flying. Most pilots prefer three-blade propellers as they are a great balance between efficiency and power, they provide more grip in the air due to the extra surface area compared to two-blade. On the other hand, two-blade is usually more efficient as they creates less drag and draw less current, hence great for long range flying.

You should also consider the sound these propellers create – when there’re more blades, it lowers the RPM at a given power so it’s usually quieter but it also depends on the design.

There are propellers with even more blades, such as quad-blade and hex-blade propellers. Quad-blade propellers are said to be great for indoor tracks and cornering, but they are less efficient than tri-blade and spin at a lower RPM at a given power. Hex-blade propellers are not recommended for normal flight due to its extreme inefficiency, but micro cinewhoops sometimes use these to improve their power due to the lack of space to use larger propellers.



When it comes to propellers, weight is an important factor to consider. In general, lighter propellers tend to perform better. Heavier propellers have more mass on each blade and require a more powerful motor to spin them. This can lead to higher torque loading, making the motor work harder and possibly decreasing overall performance.

Lighter propellers have less moment of inertia and can change RPM faster, making your drone feel more responsive. They also work better with a wider range of motors because they require less torque to spin up.

The weight distribution of the blades also makes a difference. Propellers with the blade’s center of mass closer to the hub are better. However, this means the tip of the prop gets thinner and easier to break. If the center of mass is further away from the hub, there is more drag and the propeller is harder to speed up and slow down.

What Propellers To Use on an FPV Drone

Here is a table that shows which size propeller to use with different motors and voltages..

It’s important to choose your propeller size first because it determines the size of the frame you can use.

The propeller size you choose also depends on the type of flying you want to do. The 5-inch propeller is the most popular because it’s versatile and can be used for racing, freestyle, and even carrying a full-size GoPro camera. The 7-inch propeller is better for long-range flights because it can carry a much larger battery. You can learn about all the different drone sizes in this post, I won’t repeat it here.

Here are my recommendations for 5-inch propellers..


Thrust is measured in grams. For your drone to hover, the propeller needs to produce at least 1 gram of thrust for every gram that your drone weighs. To perform stunts, or even just to take off or fly forward, your drone needs more than 1 gram of thrust per gram of weight.

Propellers produce more thrust when they spin faster and less when they spin slower. The speed of the drone also affects the amount of thrust produced. Some props perform well when the drone is stationary, but not so well during a cruise, while others perform well at high speeds but poorly when hovering. You want a prop that balances these factors and can create a good amount of thrust at different speeds.

To find the best prop for your drone, look up motor thrust tests to see what prop size work best with your motor. Keep in mind that props perform wildly differently when strapped to a thrust stand in a static setting compared to when they’re actually flying through moving air. Props can produce 20-30% less thrust in the air than on the ground.

To accurately assess prop performance, it needs to be tested at the speed your drone normally flies at. However, few people have access to wind tunnels for this type of testing. So, take performance tests with a grain of salt as they may not be an accurate representation of real-world use.


In the hobby, people often use the term “smoothness” to describe the quality of a motor or propeller. It’s not something that can be measured quantitatively, but more of a feeling that pilots have. In my experience, lower pitch props tend to be smoother because the motor can change RPM more easily and quickly. This allows the drone to respond faster to correct errors and reduces something called “prop wash”.


A propeller that creates lots of thrust with high pitch doesn’t necessarily make a drone faster than a lower pitch propeller that generates less thrust. As the propeller’s speed increases (which is measured in rotation per minute – RPM), so does the drag, requiring more torque from the motor to turn.

The theoretical maximum speed of an aircraft can be calculated using the equation:

Max Speed (in inch per second) = Max RPM * Propeller's Pitch / 60

In real life, factors such as air resistance, head wind, and angle of attack etc can all affect a drone’s speed.

Thrust affects acceleration and angle of attack, while RPM affects top speed. To achieve the best speed for your FPV drone, you need a balance between thrust and RPM.

Are Larger Props Better?

1. Responsiveness: A larger prop means a higher moment of inertia, leading to reduced responsiveness. This is particularly noticeable when using motors that typically drive 5-inch props like the 2207 size. On these motors, a 7-inch or even 6-inch prop will be less agile in responding to quick, sharp control inputs compared to a 5-inch prop. You will need a bigger motors to compensate but it will add weights and requires more powerful battery and electronics.

2. Thrust and Efficiency: Larger props generate more thrust, making them more efficient – they can carry more weight, even with the same motor. The increased efficiency means you get more thrust for the same power or the same thrust at a lower power requirement.

3. Vibration: As you increase prop size, expect more vibration. This is amplified by larger, less stiff frames.

4. Top Speed and Prop Wash Handling: Larger props tend to have a lower top speed but better prop wash handling. However, they are often more efficient, capable of maintaining higher speeds over longer periods.

Weather and Temperature

Cold weather poses significant challenges for drones. As explained in our guide “How to fly FPV in the winter“, not only does it negatively impact battery performance, but it can also affect propellers. Depending on their material, propellers may stiffen and become brittle in cold temperatures, increasing the likelihood of breaking upon collision.

Impact of Altitude

Altitude can drastically affect air density and, consequently, the performance of your FPV drone. In areas of lower air density, such as high altitudes, you’ll experience less thrust from the same motor RPM. This results in the drone feeling more sluggish and less powerful, similar to the effect of using lower-pitch propellers. Therefore, when flying at high altitudes, it’s advisable to use higher-pitch propellers to compensate for the reduced air density.

Hai Oscar, how can i know that the propeller is cw or ccw. What is the sign and difference?

Raphael 15th July 2023 - 8:59 pm

Hi Oscar!! I have a 5 inch drone with 2550kv tmotor velox v2 motors, which propeller do you recommend? I’m currently using the ethix s4. grateful

Jakru 30th June 2023 - 12:58 am

Hi Oscar

Im not sure, but i feel my 5” quad more stable to use the 6 blades than 3 blades prop. I like the floaty feeling when using the 6 blades. Do u think, i made a mistake with the setup ? Is it possible to have the floaty feeling using 3 blades with some setup ?


Oscar 30th June 2023 - 9:38 am

don’t worry, there’s no right or wrong in any setup as long as it flies in the way that suits your flying style and requirement.

Pham Phu Khang 21st June 2023 - 8:09 pm

Could someone tell me that the tri prop gemfan 51466 mck v2 can fit which thi 2300kv rs2205 motor ?

Oscar 25th June 2023 - 1:05 pm

Yes it will fit.

babipsylon 11th May 2023 - 11:58 am

What’s the effect of altitude/air density?

Adrián 3rd May 2023 - 8:53 am

Hi Oscar!
“This means that you should install the CCW prop on the motors at the top left and bottom right” -> I think you mean CW in this sentence.

Arthur 27th March 2023 - 1:00 pm

Hi Oscar,
Nice article (again).
I got a questopn abouth the Gemfan 3052-3. You would say the pitch is 5,2 inch. But the gemfan website says different.
Do you think its a mistake on the website?

kind regards,


Oscar 27th March 2023 - 1:30 pm

I am not sure, it’s either a mistake, or “52” is a meaningless number they made up to confuse users.

Joey 10th June 2023 - 8:26 pm

I read somewhere else that the last 2 numbers for that prop is in degrees. So it is a 3 inch prop with a 52 degree AOA which would put it closer at 3.3 inches (3 * tan(52)). I know that DAL props always seem to have a lower pitch than stated too. I wonder if for the 4 digit designations the last two are always in degrees and ones that are LxPxN use inches for pitch. Then again HQprops sells a 3x5x3 which should be insane looking, but the photos look pretty normal.

Maybe like Oscar said they use them like battery C-Ratings where they are defining pitch in an unconventional manner and it can only be used to compare blades produced by that company.

Chris 20th November 2022 - 10:41 pm

Thanks for all of these tutorials. I flew helis starting in 2000 with the Piccolo until quitting around 2009-2010 after having flown pretty much every helicopter from nitro to electric. Around 2015 I got a QAV250 and wasn’t real impressed. I am back building a DJI HD FPV and the naming convention has become confusing to say the least. My quad had 5030s and I see 5×4 thrown around with some in mm to make matters worse saying sub 250 can mean 250 size or weight? I was never sure to begin with so having a tutorial explaining these and the variations may help others as knowing nothing about RC could overwhelm someone doing this alone.

Pete s. 5th September 2022 - 1:05 pm

Nice Write-up but there is something incorrect in here and have been searching for the correct answer but cannot find it. 5×4.5 does mean 5 inch prop with 4.5 inch pitch, but 5045 does NOT mean 5 inch prop, 4.5 inch pitch. i have recently discovered this on accident while looking at GEMFANs website. their specs do not match the prop number description as can be seen in this example here:
I thought this was Gemfan only, but campared by eye a MasterScrew 5×4.5 with a DALProp 5045 and the pitch difference is significantly noticeable where the 5045 looks more like a 5×3. The formatting of the numbers such as “5045” is NOT always correlated to diameter or pitch as can be seen on other props on the GEMFAN website… so i dont understand why the whole rc community thinks this way.
If you have any more info on this please share!

Henry 25th May 2020 - 4:18 pm

For longer flight tome on 5 inch squad, on 6s 1700kv, should i go with lower pitch than 4 yes?

Oscar 3rd June 2020 - 12:58 am

Not necessarily, it depends on the efficiency of the motor and prop combo. Doesn’t hurt to give that a try anyway.

Moreno Antunes 16th November 2019 - 3:20 pm

What about for micro/toothpicks, I see “1mm/1.5mm” shafts but how do these work, are these kinds of props intercompatible?

Oscar 18th November 2019 - 6:38 pm

I have a post about Toothpick on this whole topics.

chuck starck 2nd October 2019 - 12:12 am

This issue of no control, flipping over etc maybe I have some insight to this for problems I’v had for a long time.
Always take the blades off EXCEPT for testing this issue.
Hold the quad down firmly on a table or bench and run the power up. I’ve found some blades that create tons of vibrations that drive the gyros crazy. I’ve been fighting an issue where out of nowhere, the quad will flip over and over. I though it was bad bearings, then ESC’s, couldn’t find the reason. Then I realized that density altitude (caused by temperature and elevation) was changing and making the quad respond differently on different days.
Using my hold down and run it up test, I found extensive amount of vibrations at different high RPM’s.
I had also been testing this a long time ago on carpet in the house. I would power it up and sort of bounce like a ball, push up, drop and catch is before it hit the carpet and some times it would flip over. This was the vibration caused by different props and RPM changes and in the end, props that ran too close to each other (about 1/8″ on the tips). I was using 6×4 props and finally went to 5×3’s cause that’s what I had and it fixed all the issues. This was a 250 Quad.

Tomcat2 28th March 2024 - 8:21 am

Man, if you hold down the quad on the ground and increase the throttle, no wonder it makes all this weird stuff as there are huge turbulences when the air it hitting the ground in high speed just a few cm below…as PID loop tries to compensate for those vibrations, it gets even worse!! Also it is completely normal that quad jumps near the ground as it creates an air pillow below and it jumps on it when the air pressure changes. It basically behaves as a hovercraft this way ;)

Peter Van Gorp 15th January 2019 - 5:09 pm

Hi Oscar,

With the trend going toward 5s and 6s setups, I have this question. If a good kv for motor with a 6inch blade on 4s is 1900-2300kv indicating a thorectical no load rpm of 7600-9200 would you pic a 6s motor that would also fall into this same rpm range such as a 1500kv motor, would a 1700 to 1900kv motor produce too many rpm for the blade?

Oscar 22nd January 2019 - 3:59 pm

It’s not the RPM that you should be worry about, it’s the current draw :) It’s hard to say without actually testing it, RPM is just a tool for estimation.

Reinkort 27th November 2018 - 8:39 am

Hei Oscar!

I am looking for the 3 blade propeller for my special prototype. This propeller must be able to move in tunnel max air flow with speed 150-200 m/s. No for lifting only for organization of airflow through special tunnel. The diameter of propeller 45-50 cm. What kind of 3 blade ( fixed pitch and angle) propeller can do this and from what company I can order such propeller?

FotoAmg 5th August 2018 - 12:18 am

Hi I mostly still fly at 2300KV 6×45 2blade props, now thinking off better efficiency, I bought 1900KV motor and 7×2.4 2blade props will it be better what do you think? I was unlucky so far with every 7inch props on racers :( oh I will use 4S battery

paul h 15th July 2018 - 9:42 am

Hello Oscar. thanks for a lot of effort to help the community with all of the web pages. A simple question perhaps. I am reading about the DYS 3542 motor that has a 5 mm dia shaft. I would like to use the 10×5 prop on this motor and it has a hole diameter of 6 mm.

DYS apparently sells a prop adaptor with this motor at Amazon. The question is will this prop adaptor actually connect the 5 mm shaft to the 6 mm centre hole?

thanks. Continue with the excellent articles!

Sebastian 24th June 2018 - 11:42 am

Make sure your motors are actually turning the props with the same rpm as they do. Perhaps the props with their much higher drag are not fixed properly to the motors. I had the same issue on a micro quad. In my case the motor bell was turnig allmost free on its own axis without turning the prop when under load – yes, those motors where realy bad quality.

Rahul 26th January 2018 - 7:24 am

Hi, I read your article and it looks like you did some good research on this prop dimensions. I actually built a small drone and now want to test the performance with two different type of propellers. Below are the pairs I bought and specification as is mentioned on the propeller body

HUBSAN Props (round edge)
Red A : 6 ~ 66
Red B : 5 ~ 55

UdiRC Props (square edge)
Red A1
Red B1

Please let me know what performance variation I can expect by using these two types of propellers. is there any equation I can apply to calculate drone performance variation between these two types of props?

Thanks a lot for your help!

Ali 11th January 2018 - 7:42 am

what is the parameters unit in formula? for example is speed in m/s or km/h? or propeller pitch in inch or meter or centim?
I guess speed is in m/s and prop. pitch is in meters… is it true?

Ian Lennox 8th December 2017 - 5:46 am

Hi Oscar, I’ve been building and flying quads. for 4-5 years now,and always read your articles as you explain things really well and use a common sense approach. I have just completed a ZMR250 [Banggood] with the 5mm arms, and with 5″ props. it flies beautifully-smooth,responsive and fast. I have a good selection of 6″ props.and wanted to try them out,as I’m using Racerstar 2205s motors-these have plenty of power,more than enough to easily spin a 6″ prop. I’ve now tried 3 different 6″ props.,2 xpointy and 1x bullnose, and the quad just won’t fly.It either just jumps up and flips over,or lifts off and goes off in any direction without responding to the controls. I’ve never struck anything like it. Do you have any ideas?
Kind Regards- Ian

Eric 22nd March 2017 - 6:00 am

Interesting, I recently faced this challenge of picking some different props on the quest to find something better.
The choice is clearly overwhelming between brands, number of leaves, shape, material, …

I ended up ordering some sets of DAL, KingKong, HQ prop, and Gemfan (PC and other compound) in 5045BN 2 blades and 3 blades, as well as some 5045 and 5040 standard.

In my experience so far, I have been impressed by how much a difference props will have in durability, punch, and autonomy

I would have to have loved to read your thoughts on the impact of material, especially regarding Gemfan who offers ABS, poly carbonate and other material.
Meanwhile, other brands like DAL and KingKong keep running with their own recipe.
