In this complete guide, we are offering a strong knowledge base about drones: the various sorts and categories of these devices, what can you use these uncrewed aerial vehicles for, as well as what to think about when being in the market for a drone.
What Are Drones?
Also called UAV (unmanned aerial vehicles), they have numerous sizes and shapes and cater to an ever-increasing number of industries and purposes. These machines can be fixed wing or multi-rotor. Multi-rotor models are likely broken down into octocopter (eight rotors), hexacopter (six rotors), quadcopter (four rotors), and tricopter (three rotors) drones
According to the widespread consensus, these models are crewless flying airplanes under control from a human drone pilot.
But be that as it may, this is not wholly true anymore amid the technological evolution for drones. Today, the term also includes underwater UAVs and AI-powered and autonomous units. It even encompasses self-flying drones.

That is not all; there is a growing quantity of terminology surrounding this type of flying device. Other names utilized for them include ROA (remotely operated aircraft), RPA (remotely piloted aircraft), UA (unmanned aircraft), and UAS (unmanned aircraft system) to define airplanes without a flight crew.
From widely-publicized military utilization of drones (fixed-wing UAVs for most of the time) to popular culture with references, for example, the Black Mirror TV shows, we can see that this product benefits a continually growing series of applications.
Is drone worth it for photography? To be sure, hobbyists and professionals have leveraged this innovation in not only video and photography but also in various other applications such as racing, transportation, delivery, inspection, to name a few. Thanks to the cutting-edge advancements of drones, they become faster, smarter (making use of AI (artificial intelligence)), smaller (or more sizable), and carry massive payloads.

How Much Do They Cost?
Their range of price is immense, mostly because of the wide assortment of drones in the market these days as well as purposes that they serve. Their costs can vary from a large number of US dollars (surveillance and camera models state-of-the-art military UAVs) to below 50 dollars (toy units and micro selfie products).
1. Expensive drones
EHang 184, the costly commercial model
Beside military-use units that are not for commercial deals, the pricey reported automaton is the EHang 184, a kind of “flying taxi” concept device from EHang, a Chinese tech firm. The cost for this sizable, autonomous passenger quadcopter model is high when compared to others out there today.
This product gets kitted out with comfortable chairs, a best-in-class control deck, and air-conditioning. What is more, the EHang 184 (dubbed EHang’s Autonomous Aerial Vehicle AAV) gives around twenty minutes of flying time and is capable of attaining speeds of more than 62 mph (100 kmh). The company has also designed a two-seater EHang 216, a hexacopter.
Augmented Aerigon Drone, the pricey camera drone
The Augmented Aerigon Drone is known as one of the most expensive uncrewed camera aircraft vehicles. BRAINFARM custom-constructed this premium device to carry the professional, high-speed filmmaking camera Phantom Flex4K.
2. Mid-range units
In the middle price range, you may want to discover excellent flagship drones from well-known brands, for instance, DJI:
3. The cheapest
You can find the least expensive crewless airplanes for under $20 US dollars. Yet, they usually are toy drones.
The great news is that whether you are looking for drones for beginners or veterans, they have been increasingly easy to purchase, being accessible in toy shops, electronics stores, as well as online affiliates. You can indeed effortlessly buy them on reliable e-commerce sellers, for example, Amazon, AliExpress, Banggood, and GearBest.
Categories of Drones

They can be split into various classifications: racing drones, camera drones, toy drones, micro/ mini/ nano drones, and underwater drones.
1. Camera drones (also known as video drones)
Video/ Camera flying models are a broad classification, but it, for the most part, incorporates professional and hobby drones intended to capture stunning video footage and photographs from the air. In case you do not know, at the top end, professional product units come with 4K cameras, are likely autonomous, and have different cutting-edge obstacle avoidance sensors.
Though the flight times and range differ, half an hour is regarded as a fantastic flying time. And for the range, it can, without much of a stretch, arrive at 7-10 km. Plus, these automatons come with various camera and video modes to optimize the quality of photographs and footage captured.

2. Racing drones
These vehicles are perhaps the largest classification of drones, and drone racing as a leisure activity and pro game becomes more and more common.
FPV (first-person view) racing uncrewed aircraft vehicles are typically a less sizable quadcopter drone or UAV (unmanned aerial vehicle), which is explicitly made for drone races. They are light, sturdy, and swift.
With regards to flying duration and range, these automatons are more limited as compared to many other drones, yet racing models are quicker than different types of drones.

3. Marine/ Underwater drones
It is a small yet quickly growing category of aircraft vehicles without a pilot, which have been, in general, more costly and, for the most part, targeted at professional users. The typical examples of professional applications are marine biology research or submerged surveillance and exploration.
For the live video feed, underwater drones usually need to get tethered to a cable. Though that way limits the range, these models can arrive at depths of many meters with ease.
Also, the products are commonly equipped with great lighting, which is fantastic for seeing underwater. They feature sensors as well for tracking purposes. What is more, the camera specs are often high to capture incredible quality film despite challenging environments at submarines.

Drones Buying Guide: What to Consider Before You Purchase
Performance-focused and hardware-focused, there are different elements to think about before picking a flying machine.
1. Types of UAVs and drones
You can find three major types of drones are available currently:
- Underwater drones
- Fixed-wing drones
- And multirotor drones
These automatons can satisfy your hobby, commercial, and professional demands. With that being said, people mainly utilize them for professional applications.
2. Range and flight duration
Though a few tethered drones are capable of flying for extended periods, most of the time, the crewless aircraft vehicles are made – or restricted – to operate for constrained timeframes.
Toy drones and racing drones just provide five to ten minutes of flying time. Meanwhile, top-grade commercial and camera models can last somewhere in the range of half an hour and 45 minutes (or longer). In case you missed it, the maximum time of flight has to do with the quantity of range or distance that the automaton can cover.
You also should have an idea of other factors which likely impact the range, say, signal/ transmission power between the controller and receiver, battery life, weather, etc. For the more favorably-priced racing and recreational drones, the range is commonly short (from 100 meters to 200). The bigger and pricier aerial (two km) and long-distance drones (ten km) have a considerable range.
3. Size and weight
Mini/ micro drones, toy drones, and racing drones tend to measure no more than 30 cm long and weigh at most 500 grams. Amid the continuous development of commercial, delivery, and autonomous drones, the weight and size of these units have been increasing.
A few drones today would be viewed as gigantic. China, in 2018, tested the FH-98 (Feihong-98), an uncrewed transport aircraft that can convey a 1.5-ton payload and a 5.25-ton takeoff weight!
Besides, Boeing tested the biggest prototype octocopter in the world in 2018. It has a substantial weight of 340 kg (747 pounds), is 5.5 meters (18 feet) wide and 4.5 meters (15 feet) in length!
On the other hand, the SKEYE Nano 2 Drone by TRND LABS is known as one of the least sizable camera drones. It is also only 2.2 cm high and measures just four cm diagonally. The weight of the model is merely 11.9 grams.
4. Remote control/ Controller
More often than not, you need to control drones employing an RC (Radio Control) transmitter or remote controller. These controllers, generally speaking, look like those you would see running RC toys.
They enable you to operate the UAV remotely. Also, their sizes and shapes vary. Moreover, they may have or not have LCD screens, and even tablets and smartphones are likely mounted.

Most preferably, the controller ought to have at least four channels. Besides, many automaton controllers run on a frequency of 2.4 GHz; for a more extended range, you will need a controller that has lower frequencies. RC transmitters can operate through Wi-Fi as well.
Last but not least, aside from checking an assortment of other technical specifications, you should get yourself a controller, which is ergonomic and convenient to use, with the control knobs and buttons simple to operate within your hands.
5. Speed
Different factors contribute to the speed of drones; they can be weather conditions, the weight of the model, its dimensions, and motor power.
Sizable professional uncrewed aircraft vehicles and camera drones usually arrive at speeds of 30-50 mph. Also, they often have a long range and flying duration and manage flights far better in adverse weather conditions.
A couple of professional and lightweight racing unmanned aircraft units are the quickest commercial drones out there nowadays. RTF (Ready-To-Fly) racing automatons can, without much of a stretch, reach more than 100 mph, yet a lot of other drones will maximize at about 75 mph.
The DRL RacerX has been the quickest recorded drone thus far. It managed to set the Guinness World Record for the fastest ground speed in 2017 at up to 163.5 miles for every hour.
6. Battery
The battery is significant for any automaton. You must account for the capacity of the battery along with how long it takes to charge fully.
The quantity of time your battery lasts relies upon its capacity (mAh, milliampere-hour as the measurement) and some other factors:
- Weather conditions (for instance, with or without wind)
- Ongoing use of the camera,
- The drone’s speed and load
The period it takes to recharge the battery may vary yet easily take as long as 120 minutes.
7. Portability
Based on the drone’s sort and size, most drones would be regarded as convenient. Racing, hobby, and toy unmanned aircraft models, specifically, are compact and relatively lightweight. Not all, the high chance is that they are modular in construction; hence, they are anything but difficult to disassemble.
For more costly camera drones, extra carry cases are increasingly typical. Moreover, a few models are foldable, which implies that you can retract the drone’s arms.
For top-of-the-line professional drones, each exertion is made to make these automatons simple to move and deploy quickly, since there may be needs for them in surveillance or emergencies.
8. Quantity of rotors
As mentioned above, drones come with various rotors (though some premium models are fixed-wing) and can be divided into the following:
- octocopter, eight rotors.
- hexacopter, six rotors,
- quadcopter, four rotors (the most common),
- and tricopter, with six rotors
There are exceptions, such as the UVify Draco 4×4. It features 16 rotors.
Another thing to know, underwater drones have numerous thrusters that are usually powerful to alter the direction and help with controlling the automaton in strong underwater currents.
9. Automated modes of flight
Drone producers have been paying more attention to adding new features to their product units so that they can become simpler to steer. Below are several most common automated modes of flight found in these flying devices:
- Follow-me: Thanks to this feature, you can ask the machine to chase after them without having to pilot the automaton manually. The drone will “follow” your controller (not quite the same as tracking with facial recognition).
- Altitude hold: This flying attribute enables the model to sit at the preset elevation and keep up its position.
- Return to home: Generally speaking, it is a one-touch function that returns the device to a preset GPS area or its pilot. A few drones “come back home” automatically since the battery is running out of juice.
- POI (point of interest)/ Orbit: Owing to the orbit mode, your UAV can hover around a particular subject you indicate. The subject can, for instance, be a vehicle, a tower, a monument, an individual, among others.
- Waypoint: You can leverage this function to plot a course for your aircraft to follow effortlessly.
10. Drone accessories
There are endless drone accessories accessible from generic suppliers of drones and particular manufacturers. They include upgrades to the drone parts, which just about any drone features, for example, propeller guards, propellers, charging units, batteries, goggles, controllers, backpacks, carry-cases, camera filters, memory cards, and others.
