Here for the Drone Propeller Price? continue reading… Propellers are devices that transform rotary motion into linear thrust. Drone propellers provide lift for the aircraft by spinning and creating an airflow, which results in a pressure difference between the top and bottom surfaces of the propeller. This accelerates a mass of air in one direction, providing lift which counteracts the force of gravity.
UAVOS Drone Propeller Blades
Propellers for multirotor drones such as hexacopter, octocopter and quadcopter propellers, are arranged in pairs, spinning either clockwise or anti-clockwise to create a balance. Varying the speed of these propellers allows the drone to hover, ascend, descend, or affect its yaw, pitch and roll.
Propeller speeds are varied by changing the voltage supplied to the propeller’s motor, a process that is handled by an Electronic Speed Controller (ESC). The correct signal is fed to the ESC by the drone’s flight controller, which relies on inputs from either the human pilot’s controller or an autopilot, and may also take into account information from an IMU (Inertial Measurement System), GPS and other sensors.
First let’s get familiar with some of the big names in the industry and their flagship models, and what they are known for.
|Dal Cyclone T5045C||5″||4.5″||3||4g|
|Azure Power 5140||5.1″||4″||3||4.5g|
|Dal Cyclone T5050C||5″||4.5″||3||5.2g|
Dal – Cyclone series – Dal is a long time favorite of many free stylers and racers. The most famous are the very responsive and powerful Cyclone 5045 and 5046. The higher pitched 5046 is known for speed and durability and its close relative the 5045 is known as the slightly more efficient version with a little more speed vs control.
HQ – V1S Series – One of the most popular props today for freestylers and racers a like. The most popular sizes have been the HQ 5×4.3×3 v1s
T-Motor – Makers of the outstanding motors ventured into the prop game. They made a very light 5149 prop that was all the rage last summer.
Azure Power – Perhaps the most unique prop design of the bunch, the boomerang style of the Azure Power is very unique and those who fly them are constantly extolling the virtues of these unique props.
Gemfan – Flash Series – A very powerful prop, my personal favorite for 2.5” or 3” props are the Gemfan flash series. They are also the maker of the popular 5152 series. A super powerful and smooth prop, that sometimes suffered from durability issues, but Gemfan went back and made a newer version of this prop with increased durability.
Lumenier – A staple in FPV made by GetFPV, Lumenier makes the Butter Cutter series of props.
Emax – Makers of the Avan series. They now have props in the whoop class size, all the way up to 5”. Noted for their extreme power and smoothness, but have historically been known to draw a lot of amps.
Reading the Prop Numbers
You may notice when looking at props that you commonly see a series of numbers associated with each one. Now different companies may structure the name of their props different leading to some difficulty interpreting but let’s break down how to read these numbers.
Manufacturers use 2 types of format:
L x P x B or LLPP x B
L- length, P – pitch, B – number of blades
We will use HQ V1s series as as an example. One popular model that I use is the HQ 5 x 4.5.x3 v1s. Here we see 3 numbers. The first 5 indicates the size of the prop, in this case 5 means 5”. The second number 4.5 refers to the pitch of the prop. And the last number 3 refers to the number of blades on the prop. V1s is the props designation or model.
Drone propeller Characteristics
Props range from Tiny Whoop class 31mm variety, to 6”+ long rage size, to even bigger for commercial or Prosumer applications like DJI Inspire or Phantom.
Think of prop pitch like using a paddle in a canoe. If you push straight back with your paddle parallel in the water to you, you will have the max force and each push will go slower. If you push at a high angle, you can cut through the water faster, but it will push you ahead with less force.
A lower pitch will always move faster, but push you ahead with less thrust.
A higher pitch will mean more thrust per revolution, for greater speed but less fine control.
Higher pitch will also be providing higher thrust, but in combination with more amp draw. That extra work will demand more from your battery.
Number of blades
The number of blades affect both flight and efficiency. Fewer blades = more speed, and less amp draw or more efficiency. More blades = more control, but lower efficiency and lower speed.
The compromise often is to run a 3 blade prop for most 3-7” quadcopters. But for high speed runs you will often see 2 blades, and for indoor crafts where you want the most control possible vs speed you will often see 4 blades.
Props today are most often made of polycarbonate. Different combinations of materials, colors and ingredients can make for a stiffer or more flexible prop. A more rigid prop can allow very fast speeds, but can also break more easily on impact.
How do you pair a prop with a particular motor and quad?
You will also want to match a prop to a motor. A smaller motor like a 2205, will not be able to push a high pitch prop like an HQ 5×4.8 v1s without draining a lot of battery. It would do much better with the lower pitch 5×4.3 v1s.
A heavier motor like a 2207, will have more power, and ability to push that larger prop to allow you the maximum straight line performance. But as mentioned earlier, this will demand a lot from your batteries.
When testing a new prop, always make sure to land, check motor temperatures, and keep a close eye on your voltage readout on your On Screen Display to ensure you do not over discharge your battery.
Installing props on your quadcopter? What tools do you need? Any 8mm wrench or socket wrench will do. But I always recommend a dedicated prop tool such as the Piroflip branded one.
Also, pro tip, keep more than 1 prop tool with you. I generally have 2. The reason is, sometimes we end up keeping one in your pocket and forgetting to put it back. Nothing like being out at a nice place to fly, and having to go home because you could not get your broken prop off.
So don’t let this ground you, and make sure you have the right tools. For smaller T prop sizes, you will want a 1.5mm hex driver.
There are 2 propeller direction options. The traditional betaflight setup which is props all turning in. And the Reverse which is props turning out.
The both should feel the same in the air, but props turning out can help to push you away from objects, where as traditional props in will pull you in. The downside, is that props out will throw any cut grass, dirt or grime you land into directly into your center stack.
So be warned. It is a great option for some, especially if you fly near a lot of trees, but I personally do the traditional way. There are many ways to remember your prop orientation but I use this method. (for traditional mounting).
If I look at a prop straight on, the blade should point down on the left side, this goes to the top left. If I look at it the same way and the blade points down on the right side, it should go to the top right. Your rear props are the same across the diagonal.
Prop Size Recommendations
31mm or 40mm are the whoop class sizes. These will typically run with Whoop style ducts and be safe to bounce around inside your house with. There are 2-4 blade varieties and new offerings by HQ, Team Black Sheep and Gemfan.
My favorite for this is the 2.5” size. When on 4S with a target weight of 80-100grams dry weight you have enough speed to have fun but still a fairly light craft. This is best for an empty playground to play around.
If populated whoop class is best, because of the 25-35gram weight and the ducted guards that protect if an impact is made. My favorite in this size is the Gemfan 2.5” 2540 Flash series prop. Many also prefer the very attractive HQ.
Or small field, parking lot – 3” – There are 2 main types of 3” props, the traditional size prop nut where the Gemfan 3052 Flash prop is king. Or the T style Mounting prop, where the HQ 3” T style prop is an excellent choice.
Gemfan recently released a Wind dancer version that come with a set of adapters that allow you to run both regular size props or T style mounting props to accommodate a wide range of motors.
For racing, the 5” prop is the standard. You can play with the pitch and pairing of your motor to find the right mix for you.
Like racing the 5” is the standard, but often different pitches can be popular for additional response preferred over top end speed.
This is where you get to 6” and 7” props. These will pull more power, but long range experts have found that pairing with a large battery and the proper mid KV can allow you to achieve impressively long flight times.
For 6″, HQ 6×4 and Dal 6×4 are some preferred options. Note that in 6” ( Dal fly smooth but do not have the same durability as the 5” options).
For 7″ HQ 7×3.5 fly well at high throttle ranges, but for a good all around option the Dal 7x.56 are regarded as the best.
Long range community has let me know that one thing to look for when you go 7” or larger, is that you want thicker blades.
For wings, while many do run Quadcopter props, APC makes a range of purpose built props specifically for wings. These involve a lot of variation based on your needs, size of wing, weight, specs and purpose. So before you dive in, consult your local Wing Commander for more advice.
When should you change your props?
If you crash and a prop is bent, often times you can bend it back and it will fly fine. Some prop models will bend back to original shape and stay there and will fly fine. Some may keep a crease where the bend was.
Creases, cuts, nicks, or chunks missing will all cause poor flight performance. The newest betaflight software with dynamic filters can filter much of this out, but keep in mind you may be putting additional stress on your electronics in these scenarios.
If you are absolutely low on props you can keep flying but always check your motor temperatures when landing to make sure that bad prop is not warm.
The last thing you want to do is risk burning a pricey motor or electronic speed controller over a fairly inexpensive prop. Rule of thumb? When in doubt? Change it out. Keep in mind, that newer props fly better, smoother and many times faster. And when you are learning you do not want your muscle memory to build up on bad props, so keep those in mind and change them at your discretion.
If I am doing light free style, a set of props can last a long while. But if I am racing, I may change props 2-5 times in a single day to make sure I am getting maximum performance, and when doing hard throttle, on a bend or banged up prop is when you are the most in danger of putting electronics at risk.
How many sets should you keep in your personal stache? Nothing can keep you grounded faster than not having a few $2-3 sets of props. So when the sales hit, stock up, buy big and take advantage of the prop discounts at the large retailers like www.piroflip.com and www.rdq.com.
Drone Propeller Price
It’s a good idea for every FPV pilot to both select a favorite quadcopter props and stock up, but also try new offerings always searching for more control, more speed, more durability and a better cost. To have a prop that allows you to fly to your full potential is a constant quest to become better at FPV.
I personally take advantage of the prop bulk pricing discounts and usually order 20-40 sets at a time and keep a large stock. This allows the best bang for the buck, and allows you enough stock that you can combine these bulk discounts with seasonal sales and stock up for the lowest price possible.
The Basics of Drone Buying
Drones are remote-control (RC) multi-rotor flying devices that provide new ways of looking at the world by taking photos and videos from different perspectives. Many of today’s RC drones offer first-person viewing (FPV) in real time, putting users in the driver’s seat for an exciting joyride where they can explore the air with a pilot’s perspective.
Before it’s time to fly, it’s important to first consider three main things: Budget, experience, and intention. Each of these will vary between shoppers since, ultimately, the perfect drone is different for everyone. Here are some quick tips on what to think about before buying:
- Opting for a cheaper toy drone is a great way to learn the basics before investing in a higher quality device.
- Most drones on the market today will fall into two price categories – under $100 or over $500. Cheaper drones will have very basic features and controls while pricier ones can include high-definition camera equipment and autonomous flight modes.
- A majority of drones are fairly easy to repair following a crash, but the cost of parts can add up.
- Flight times for all types of drones is limited by battery life.
- Learn to stay within the drone’s signal range.
- If possible, use a simulator to get to know the drone better before flight.
Types of Drones
At the lower end of the drone spectrum are toy drones, like the Parrot Mambo and the Hobbico Dromidia Kodo. These simple and inexpensive drones come in at about $100 and are more focused on fun than features. Their controls are straightforward and easy to learn, and they can be accessed through a smartphone app or included remote control.
The flight times of beginner drones and drones for kids are also more limited – generally less than 10 minutes, or even fewer than five for the very cheap models. Designed to perform some tricks, like midair flips, spare parts are available at fairly low prices if anything goes awry. Some small drones also come with video cameras, though the quality captured tends to be poor. But don’t count them out too soon – getting a cheap drone is a fantastic way to learn to fly before upgrading to a more expensive model. They also won’t cost a fortune to fix or replace in the event of a crash.
Drones with cameras – like the DJI Mavic Mini, the Parrot Bebop 2, and the GDU Byrd – are specifically designed to capture images, and range in price from $500 to $1,500. Built to provide a steady platform for the lens, which can either be an add-on or built-in, these sophisticated flying machines are more focused on recording high-quality video and still images than performing midair tricks. Because the equipment needed makes them larger and heavier, video drones need to be registered with the FAA.
Video drones often come with gimbals, which is a system designed to pan and tilt the camera – and cushion it from the motors’ vibrations – to cancel out the drone’s motion and keep the lens steady. Gimbals can either come as an electronic system built into the camera, as seen in the Parrot Bebop 2, or as a physical system made of motors and gears, like in the Mavic Air. Either way, the gimbals allow users to direct the camera at whatever angle they like, to capture beautiful pans like those seen in nature documentaries.
Bigger drones need bigger batteries, which often translates to longer flight times. A fully charged battery typically lasts a video drone around 20 minutes, and they can usually be swapped for spares to extend the session. Like toy drones, video drones are also built to be repaired, and replacement parts are generally easily available. Parts are relatively inexpensive as well, with Mavic Air’s replacement rotor blades running about $20. The quality of video these drones capture can vary widely, from the Bebop 2’s decent but sometimes choppy HD video to the Mavic Air’s super-smooth panning shots. While the videos produced by cheaper models like the Bebop 2 will be good enough for most use cases, it’s worth investing in the more sophisticated DJI drones when quality’s the main focus.
From photographing special occasions to surveying construction sites, drones are being used for an ever-expanding range of purposes. In fact, dedicated drone film festivals have popped up in major cities like New York and Berlin to showcase the creative new ways amateur moviemakers are utilizing their flying machines. Not only that, but the more innovative drones – like the Mavic Air – have built-in autonomous flight tech to make journeys on their own. They can even use cameras to detect and avoid obstacles in the way of their flight path. These more advanced drones allow users to play with their device’s autonomy by letting them navigate a predefined course on their own via GPS. Autonomous flight does, however, come with some restrictions – these drones must be registered with the FAA and have to be kept in the pilot’s line of sight at all times. The pilot must also be able to take back control of the drone at any point.
With the rise of drones came the rise of drone-based competitions – and drone racing might just be the most exciting of all. Racing drones are on the smaller side and designed specifically to offer pilots speed and agility. Users see through their drone’s lens via first-person-view headsets, navigating around a course and trying to beat other fliers. Most racing drones are adapted by hand to shed unnecessary weight or increase motor power. Cheaper models, like the Aerix Black Talon 2.0, start at about $115. Ready-to-fly drones on the higher end of the spectrum, such as the Uvify Draco, can run up to $700.
Drones can be an incredibly fun and fruitful new hobby, but they must be flown responsibly. Even a small toy drone can hurt someone if hit by it, and fingers can get injured if caught in the rotor blades. To fight this, some drones have built-in shields to protect the rotors, but even these aren’t foolproof. It’s best to fly any kind of drone, big or small, with proper care and caution. Here’s five quick tips for drone safety:
- Know the drone. Before the first flight, take the time to read through the instruction manual and get familiar with the controls.
- Check the drone before flight, looking for any damage to the motors or rotors that could fail in the air.
- Never fly near people or animals.
- Fly with caution, particularly when first using a drone or taking a new one for a spin. Always be sure to land before the drone’s battery runs outs.
- Fly with care. Drones can be noisy, annoying and even scary to those near their flight path. If someone asks to stop flying, be reasonable and courteous.
To learn more about drone safety, the Academy of Model Aeronautics (AMA) is a fantastic resource on all things drone. The AMA can help connect drone enthusiasts with others in the area to share both beginner’s flying techniques, and more advanced tips and tricks. Remote-control flying clubs often meet regularly to discuss and fly drones together. But remember that with great power comes great responsibility. Make sure to update all software and firmware before any takeoff, and read the drone’s manual thoroughly before use. For FAA registration requirements and further information on drone safety, check the FAA website. Additional local jurisdiction requirements may apply, so it’s important to stay informed on the latest drone regulations for the area.
Drones & The Law
Recently, the Federal Aviation Administration (FAA) introduced registration requirements for anyone flying a drone weighing over 250g recreationally. Most drones that fall under the toy category will not have to be registered, while those built for video, racing and autonomous flight likely do. Drone registration can be done via the FAA website – and separate, more stringent requirements are applied to professional drone fliers.
Once registered, the registration number must be displayed on the drone. This can be as simple as a sticker or shipping label placed under the battery, along with the owner’s name and number in case of theft or loss. The FAA also defines restrictions on where drones can be flown. They can’t be flown higher than 400 feet, in restricted airspaces, or over emergency areas, like traffic accidents or wildfires. They’re also banned from flying through national parks and cannot be flown within 5 miles of an airport without informing the air traffic controllers. Federal, state, and local regulations can vary, so check with the organizations directly if unsure.
Drone Accessories & Add-ons
Additional hardware can be added to drones that have ample lift from their propellers and motors. Lift specs can be found via the drone manufacturer’s website. In general, drones built to support external cameras are usually equipped to carry an additional half pound or more of weight above that of the drone on its own. Added weight increases stress on the motors and can affect flight time and stability.
The most popular and useful drone accessory is undoubtedly the spare battery. Drone batteries can provide between 5 and 25 minutes of power in the air per charge but can take an hour or longer to recharge. Fortunately, most drone batteries can simply be replaced with a freshly charged one when the power levels get low. To get the most airtime out of each flying session, users should invest in several spares.
The next most useful accessories for drones are spare propellers and parts. Because occasional mishaps and less-than-perfect landings are an inevitable part of flying drones, they were designed to survive crashes. The exterior components are made from sturdy materials – such as polypropylene foam and carbon fiber – that protect the more sensitive parts, like the CPUs, motors and transmitters. The parts that break the most easily, like the propellers, are the cheapest and easiest to repair or replace. New drones often have extra propellers included, and additional spares are usually available for purchase separately as well. Remember that drones need different propellers to spin clockwise and counterclockwise for stability, so it’s wise to get both kinds of spare propellers.
Depending on use cases, other drone add-ons that may be of interest include LED bands, propeller guards and extra landing gear. For photography drones in particular, various lens filters can be added to alter saturation levels, reduce glare, and more. Getting a quality bag or case specifically designed to carry a drone is an important investment as well. Drone bundles can often be found with a number of accessories. Drone cases should have a foam interior built to fit the device and its accessories and protect them from damage during transit.
