Maximum flight time

Maximum flight time of a quadcopter on one full battery charge. This indicator is quite approximate, since it is most often indicated for ideal conditions - in real use, the flight time may be less than stated. However, by this indicator it is quite possible to evaluate the general capabilities of the copter and compare it with other models - a longer declared flight time in practice usually means higher autonomy.

Note that for modern copters, a flight time of 20 minutes or more is considered a good indicator, and in the most “long-lasting” models it can exceed 40 minutes.

Viewing angles

The viewing angle provided by the standard quadcopter camera; for optics with adjustable zoom, usually, the maximum value is taken into account.

The viewing angle is the angle between the lines connecting the centre of the lens to the two opposite extreme points of the visible image. Usually measured along the diagonal of the frame, but there may be exceptions. As for the specific values of this parameter, in modern copters they can range from 55 – 60 ° to 180 ° and even more. At the same time, a wider angle (ceteris paribus) allows you to simultaneously fit more space into the frame; and a narrower one covers a smaller space, however, the objects that are in the frame look larger, it is easier to see individual small details on them. So when choosing by this parameter, you should consider what is more important for you: wide coverage or an additional zoom effect.

Camera stabilization

Stabilization system built directly into the complete drone camera.

Any stabilization system is designed to compensate for vibrations and shakes, thus providing a stable image, without shaking or sudden movements in the camera. This function slightly increases the cost of the device, but the video quality increases noticeably. On the other hand, stabilization makes it difficult to perform complex maneuvers, since its use worsens the feedback: changes in the camera image do not quite correspond to changes in the drone’s position in space. In light of this, in devices that have an acrobatic mode (see “Flight Modes”), such a system can be switched off.

Note that specifically in the camera, stabilization is most often carried out according to the electronic principle: reserve space is allocated at the edges of the matrix, and in the event of vibrations or shocks, the camera “pulls up” a fragment of the image from this reserve, keeping the image in the frame motionless. This format of operation somewhat reduces the useful area of the matrix, but is inexpensive, does not affect the weight of the camera and does not complicate its design. A more effective, but also more complex and expensive option is a built-in optical stabilizer, which uses a lens with a moving lens system.

In addition, another method can be used to stabilize the image - a mechanical gimbal stabilizer. However, such a gimbal is not part of the c...amera, so its presence is specified separately (see below). At the same time, some copters provide both functions at once - both built-in stabilization and gimbal; this ensures maximum efficiency.

Memory card slot

The presence of a slot for memory cards in the design of the quadcopter.

Usually, this function is provided in models equipped with cameras (see “Camera type”), and the cards themselves are used primarily for recording captured photos and videos. However, in some models, other data can be stored on such media — GPS tracks, flight routes, flight programs, etc. Anyway, cards are convenient, first of all, by the ability to quickly transfer data between the device and other devices that have a card reader (in particular, laptops).

It is worth noting that different devices can be designed for different standards of memory cards, and the media themselves are usually not supplied in the kit. Therefore, before choosing a card, you should clarify according to official data which type will be optimal for your model.

Flight modes

Return home function. With this function, the quadcopter can automatically return to the starting point. The specific details of this feature may vary. So, some models return "home" at the user's command, others are able to do it on their own — for example, when the signal from the remote control is lost or when the battery charge is critically low; in many devices, both options are provided at once. Also note that this function is found even in models that do not have a GPS module (see "Sensors") — the copter can navigate in space in another way (by inertial sensors, by a signal from the remote control, etc.).

Follow me mode. A mode that allows the quadcopter to constantly follow the user at a short distance — like a "personal drone". The way to implement this mode and the equipment required for it can be different: some models track the direction to the transmitter and the signal strength from it, others constantly receive data from the GPS module of a smartphone or other gadget and follow these coordinates, etc. Anyway, such a mode can be useful not only for entertainment, but also for quite practical purposes — for example, for using a quadcopter as an “air chamber”, constantly located next to the operator and at the same time not occupying hands.

Dronie (distance). Initially, the term “dronie” refers to a selfie (photo or video) taken from a...drone. This mode is mainly intended for such tasks. And its essence lies in the fact that the copter smoothly moves away from a certain object along a given trajectory, keeping this object in the centre of the frame. The classic version of flying in Dronie mode is moving away first horizontally, then horizontally and up; however, in some models, the copter’s trajectory can be further configured. Frame management can also be carried out in different ways — from simple pointing at a certain point and ending with the selection of an object on the screen with further "smart" tracking of this object. Anyway, for all its simplicity, such a shooting technique allows you to create quite interesting videos: for example, in this way you can first capture a group of people in close-up in one video, then the beauty of the landscape around them.

Rocket (distance up). A flight mode in which the copter smoothly rises to a predetermined altitude along a strictly vertical trajectory. Similar to the Dronie described above, it is mainly used when shooting video: first, a certain scene is shot in close-up, and as it rises, the camera covers an increasingly wider area around this scene. Usually, in Rocket mode, you can pre-set the height at which the device will stop.

"Orbit mode" (flying in a circle). A mode that allows you to launch the copter in a circular orbit around the specified point. It is also used mainly for shooting video: in such cases, the camera remains constantly pointed at a given object, but the angle and background, due to the movement of the drone, are constantly changing. In the "orbit" settings, usually, you can set its radius, height and direction of movement, as well as the angle of the camera.

Helix (circle in a spiral). Another mode used as an artistic technique for filming videos. In this mode, the copter, keeping a given object in the centre of the frame, moves around it in a spiral, gradually moving away and increasing its height. This allows you to get the maximum variety of angles and angles of coverage.

Note that Dronie, Rocket, Helix, and Orbit modes originally appeared as part of the proprietary QuickShot toolkit in DJI's Mavic series drones. However, later similar functions were introduced by other manufacturers, so now these names are used as common nouns.

Flight plan(Waypoints). The ability to set a specific flight route for the quadcopter, by control points. This feature is very similar to the GPS waypoint flyby (see above), but it works differently, without the use of GPS navigation. One of the most popular options is building a route in the smartphone application through which the copter is controlled; when the programme is launched, the smartphone issues a sequence of commands corresponding to the route to the device. In general, the Waypoints mode is not as accurate as a GPS waypoint flyby and offers fewer options. Therefore, this function is mainly for entertainment purposes; if the copter has a camera, it can be useful for taking a selfie or a simple video.

Flight by GPS points. A mode that allows you to launch a quadcopter along a specific route — by setting individual route points to the car in advance (according to GPS coordinates) and the order in which they are passed. In addition, additional settings may be provided — for example, speed and altitude on individual sections of the route. This function is similar to the Waypoints mode (see below) in many ways, but it is found mainly in mid-range and high-end devices. At the same time, the use of GPS provides higher accuracy, which allows the drone to be used for professional purposes. For example, if you set a route for shooting from the air in this way, the operator will be able to fully concentrate on working with the camera, without being distracted by controlling the copter.

Acrobatic mode. A special mode for performing aerobatics. Note that the specific meaning of this mode may be different, depending on the level and purpose of the copter. So, in the simplest entertainment models, automatic programs are usually provided that allow you to perform certain aerobatic manoeuvres literally “at the touch of a button”. And in advanced devices in flight mode, the stabilization system is turned off, and the drone is very sensitive to operator commands; this requires high precision in control, but gives maximum control over the flight.

Gesture control

The ability to control the copter with gestures.

The implementation of this function can be different. The simplest and most inexpensive option is smartphone control, when commands are given by turning and tilting the gadget. There are models where the accelerometer and gyroscope are built directly into the remote control, and you can control it with hand gestures with the remote control. Another, more expensive and original way is to recognize the position of the user's hands using the built-in camera. Such devices usually have a set of commands tied to rather specific movements. For example, by folding your fingers into a “frame”, you can turn on the burst photography mode, with a wave of your hand you can call to yourself, and the device will perceive the outstretched palm as a landing pad.

In general , gesture control provides at least additional entertainment, and in some cases can be useful from a practical point of view.

Range

The range of the drone is the maximum distance from the control device at which a stable connection is maintained and the device remains controlled. For models that allow operation both from the remote control and from a smartphone (see "Control"), this item indicates the maximum value — usually achieved when using the remote control.

When choosing according to this indicator, note that the range is indicated for perfect conditions — within line of sight, without obstacles in the signal path and interference on the air. In reality, the control range may be somewhat lower; and when using a smartphone, it will also depend on the characteristics of a particular gadget. As for specific figures, they can vary from several tens of metres in low-cost models to 5 km or more in high-end equipment. At the same time, it should be said that the greater the range of communication, the higher its reliability in general, the better the control works with an abundance of interference and obstacles. Therefore, a powerful transmitter can be useful not only for long distances, but also for difficult conditions.

Video transmission frequency

The frequency of the radio channel used to transmit the video stream from the camera on board the drone to the receiving device: smartphone or tablet, control panel or pilot’s video glasses. The most common frequencies are 2.4 GHz and 5.8 GHz; video data transmission at a frequency of 1.2 GHz is less common. This parameter directly affects the quality and stability of the video signal, depending on environmental conditions, as well as accompanying interference from other devices. Thus, for receiving video from FPV drones, the most preferable frequency is 5.8 GHz, which is due to a wide selection of channels and high data transfer rates.

Information display

The presence of an information display on the quadcopter control panel.

Note that this feature should not be confused with the FPV broadcast screen (see below). The information display is usually a simple segment display capable of displaying numbers, individual letters, and, on some models, a limited set of special icons. However, even such equipment significantly expands the capabilities of the remote control and allows the operator to receive a lot of additional information: battery charge, signal level, range, flight altitude, etc. At the same time, the auxiliary screen is inexpensive and can be used even in low-cost models. And in advanced drones, it may well complement the broadcast display: separating data into different screens contributes to ease of control.
