Comparison Syma X12S vs Syma X11

General drone specialization.

This parameter is specified in cases where the device has a clearly defined specialization and is noticeably different in equipment/functionality from conventional quadcopters for entertainment purposes. In our time, the following types of drones are distinguished: mini-drones, racing vehicles(including in the form of racing mini-drones), selfie drones, kits for battles, as well as industrial/commercial solutions. Here are the features of each of these options:

— Mini-drone. Miniature devices with dimensions of no more than 150 mm (length and width) and a weight of no more than 100 g. This allows them to be easily transported from place to place, as well as to fly even in confined spaces - right up to city apartments. At the same time, many mini-drones are intended exclusively for entertainment, but there are also models with quite advanced characteristics. But the communication range of such equipment, as a rule, is quite limited (although, again, exceptions are possible); the same applies to carrying capacity.

- Racing. Devices originally created for drone racing. Such races require not only fast completion of the tracks, but also the ability to accurately fit into a given trajectory; Therefore, racing quadcopters differ not only in speed, bu...t also in control accuracy. In addition, among such machines there may be modifications for complex aerobatics (freestyle, 3D) - in their characteristics the emphasis is even more shifted to accuracy and responsiveness. It should be borne in mind that most racing models are not only expensive, but also quite difficult to operate and are designed for experienced pilots; so it hardly makes sense to buy such a device for initial training or entertainment use.

— Racing mini-drone. A variation of the racing machines described above, characterized by reduced dimensions and having corresponding features. On the one hand, these features include ease of transportation and the ability to be used in confined spaces, on the other hand, a relatively low load capacity and communication range.

— Selfie drone. Copters designed primarily for taking selfies. Among the main features of this technology are its small dimensions and the absence of a classic remote control: control is carried out either via a smartphone or using gestures through a special compact controller. This format of work eliminates the need to carry a bulky remote control and allows the operator to look natural in the frame - posing for a photo, rather than being distracted by controlling the drone. And some advanced models provide additional functions that make shooting even more convenient: face detection with autofocus and auto-centering, Follow Me mode (see “Flight Modes”), etc.

— Industrial/commercial. High-quality copters designed for professional use: photographing and video shooting from high altitudes in high resolution, “inspecting” industrial facilities and land plots, spraying fields, etc. In addition to their large dimensions, they are characterized by a long range and flight altitude (and even and others are usually calculated in kilometers), high carrying capacity and extensive functionality. Thus, many models allow the installation of heavy advanced cameras (some are even initially designed for certain models of professional cameras), others have built-in “optics” with advanced capabilities (for example, with a high magnification factor or support for shooting in the IR range). The design usually provides for a large abundance of sensors. And some models may have more specific functions - for example, detecting other aircraft nearby. Of course, such functionality is not cheap.

— Combat (sets for battles). Drones designed to organize air battles. As a rule, they are sold in sets of two cars - so that the fight can be organized immediately, without purchasing anything additional; and most models allow you to organize group battles (at least “all against all”) - for this it is enough to buy several identical sets. The role of the “gun” in such a copter is usually played by an IR emitter, and hits are recorded using appropriate sensors. For control, a smartphone or other gadget is usually used, and the control application can provide very interesting and unusual functions - for example, statistics for each player with experience points received for battles, as well as special “skills” (temporary invulnerability, unusual maneuver, etc.) . p.), purchased for these points and activated by clicking on the corresponding icon in the application.

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.

The capacity of the battery supplied with the quadcopter.

Theoretically, a larger battery can provide a longer charge time. However, keep in mind that this time also depends on the power consumption of the copter — and it is determined by the power of the engines, dimensions and weight, as well as a number of other features. In addition, the actual battery capacity is determined not only by ampere-hours, but also by its nominal voltage. Therefore, only quadcopters with the same battery voltage and similar operating characteristics can be compared by amp-hours; and it is best to evaluate battery life by directly claimed flight time (see below).

Battery model for which the quadcopter is designed. Most often, such a battery is supplied with the device, and data on the battery model is not needed for everyday use. At the same time, such information can be useful, for example, if the battery or "charging" to it is out of order and needs to be replaced, or if you are looking for a backup battery.

General dimensions of the device. A fairly obvious parameter; we only note that for models with a folding structure (see above), in this paragraph, the dimensions in the working (unfolded) position are given, and the dimensions in the folded form are specified separately.
