How to choose a quadrocopter: what to look for

The quadrocopter market is counted in hundreds of models that vary in size and purpose. According to the second parameter, can be divided into two groups – “entertainment” and “for video “.

  1. The “entertaining” quadrocopters are usually relatively small, inexpensive and low-functional. But at least they fly, and on this thank. Sometimes such quadrocopters are equipped with a small built-in camera to make it more fun however her photographic characteristics are far from perfect.

  2. Quadrocopters “for video” are large in size, high price and lack of an internal camera. She is either external either not included. Devices that are not complemented camera, you can equip GoPro or a similar device. In this case It is important to evaluate the presence of the mount.

According to the type of supply, quadrocopters come in two types – RTF (ready to fly out of the box) and national teams. First maximally easy to use, but are expensive, and it is advisable to buy them in offline stores: when ordering from abroad, transport companies may not handle the goods carefully enough. National teams quadrocopters resemble IKEA furniture: there is a bunch in the box parts from which the device, ready to use, is assembled. You will also have to configure them yourself, according to the instructions. But they are cheaper.

These are the two most important criteria when choosing a quadrocopter. Need to determine the intended purpose of use and willingness to conduct a couple of evenings for the assembly and configuration of the device. Among the others important parameters can be identified:

  1. Type of quadrocopter;

  2. The presence of a camera;

  3. Flight characteristics: range, speed and time;

  4. Type of drive;

  5. Additional features and specifications.

  6. Equally important is the manufacturer.

Types of unmanned aerial vehicles

Drones, or unmanned aerial vehicles (UAVs), vary by the number of screws used.

  1. Tricopters, as the name implies, are equipped with three screws. Such devices are cheaper than other drones, but bad Suitable for flying outdoors. Tricopters unstable stay in the air, so due to the wind they stray off course or even are falling. In addition, such lifting force of such drones is small, therefore they are not equipped with an external camera. But thanks to the highest maneuverability tricopters calmly go through complex trajectories.

  2. Quadrocopters are the most common type of UAV. These drones equipped with four drives providing high lifting strength, stability in the air, optimal maneuverability and range flight. Quadcopters are recommended for both beginners and professional users.

  3. Hexacopters and octocopters are equipped, respectively, with six and eight screws. Due to this, they are distinguished by high carrying capacity and the “upper bar” of flight. And finally, such drones retain flight ability even if one is damaged screw. However, hexacopters and octocopters are usually superior in price. quadrocopters and tricopters.

The main criteria for choosing a quadrocopter

quadcopter selection criteria

Camera availability

The presence of a camera directly determines the purpose of the quadrocopter. So if you just need a radio-controlled drone for fun, models that are not equipped with a photographic module are suitable. Drones without cameras are cheaper than others and are suitable, for example, for training piloting.

Drones with integrated camera are suitable for undemanding users. In such devices, a sensor is installed with resolution from 5 to 13 megapixels, shooting with a small detailing.

Drones with an external camera – a solution for professional operators. GoPro or professional DLSR is attached to them, receiving videos and photos in high resolution or with required optical properties. The only drawback of such drones – high cost: quadrocopters with an external camera belong to the highest priced options.

Flight characteristics: range, speed and time

When choosing a quadrocopter, it’s worth evaluating possible options use. Then it will become clear which of the flight characteristics is prevailing.

So, for fans of just entertainment, drones with maximum time spent in the air (from 20 minutes); for operators – with a maximum range (from 300 meters); and for riders – at maximum speed (from 100 km / h).

type of drive

In quadrocopters, collector or brushless type. The first are low in price, but with prolonged use overheats and therefore needs periodic replacement. Quadrocopters with brushless drives differ in durability and the minimum take-off time, however are more expensive and are installed only in large drones.

additional characteristics

Among the additional characteristics and capabilities of quadrocopters can distinguish:

  1. Programmable flights. Can pre-draw trajectory of movement on the map or through a simple algorithm. Movie enthusiasts will especially like this because automates scene creation;

  2. Follow me mode. Useful feature for sports lovers (e.g. snowboarders). In this mode, the quadrocopter independently follows the person to be shot;

  3. Wi-fi module. The quadrocopter equipped with it can be controlled with a smartphone or other mobile device;

  4. GPS module. Useful feature for creating programs or just tracking the movement of the quadrocopter on the map;

  5. Protection for the blades. Structural solution involving installation on a quadrocopter of a special “mesh” that protects device with bumps and falls. Useful solution for newcomers.

  6. These are not the only optional features, however “universally useful.”

Features of choosing a quadrocopter for a child

choose a quadrocopter for a child

Best for training piloting quadrocopters with blade protection. They will “survive” after collisions with a wall or tree.

A good version of a quadrocopter for a child is a mini version. Such devices are low cost and help learn skills piloting. Depending on the interests of the child, you can purchase both the RTF version (ready to fly out of the box) and the national team.

If the child plans to take video, you can turn attention to quadrocopters with a built-in camera. And after he “gets his hand”, it is worth picking up a larger model, to which You can connect a GoPro or a DSLR.

Features of choosing a quadrocopter with a camera

The most important quadrocopter parameter with an integrated camera is photographic characteristics of the sensor itself and the complete the lens. First of all, pay attention to the type of lens. Wide-angle lenses are better for landscape photography.

In addition, the physical resolution of the sensor is important. The higher it is the more detailed the resulting image will be. Wherein extrapolated resolution (for example, from 13 MP on the sensor programmatically easy to get 4K on the finished video) special doesn’t matter.

However, high-resolution video (Full HD, 2K, 4K) is usually takes up a lot of space on a memory card and requires speed external drive from 10 Mbps. Therefore it is very important that quadrocopter supported MicroSDHC or MicroSDXC (up to 64 GB or up to 2 TB, respectively).

Choosing a quadrocopter with a video camera

For professional photography quadrocopters with built-in The camera does not fit. Qualitative “picture” can only be obtained to an additional device – for example, a connected GoPro or “DSLR”. Therefore, it is very important that the quadrocopter is equipped appropriate mount.

In addition, quadcopter lift is important. Even the smallest DSRL cameras and mirrorless cameras weigh around 500 gram, but more professional equipment complete with the lens can have a mass of more than a kilogram. Choosing a quadrocopter under the used camera, you should pay attention to the maximum weight that the device can lift.

Not only high-quality quadrocopters are suitable for video recording (like DJI Phantom 3), but also hexacopters or octacopters. Such devices are more “reliable” held in the air, better resist wind, and also have great lift.

Choosing a quadrocopter for beginners

First of all, when choosing a quadrocopter for training, it’s worth pay attention to the budget sector. It is there devices at a price of up to 10,000 rubles – which, in principle, is not much “hit the pocket” if they break on the first day use.

The disadvantages of budget quadrocopters are low time battery life, small distance and flight altitude. And dignity of course, that they are able to educate piloting – that is, basic device management skills, moving in a three-dimensional, dynamically changing space. And then You can buy this flagship quadrocopter.

Features of the choice of a racing quadrocopter

racing quadrocopter

When choosing a racing quadrocopter, you should pay attention to “format” of the device: micro or nano (up to 50 and up to 20 grams of weight in assembled condition, respectively); as well as the maximum the speed he develops. However, such drones are usually small flight time – about a few minutes.

When choosing a full-sized drone, you should pay attention to its mass (the smaller – the better) and, again, the speed of flight. Usually it is indicated by the manufacturer directly in device specifications.

How to choose a battery for quadrocopters

The main criteria when choosing a battery for a quadrocopter are:

  1. Weight and dimensions;

  2. Number of cells and output voltage;

  3. Capacity;

  4. Current output;

  5. Connector

  6. Estimated parameters.

Weight and dimensions

The main requirement for the battery is that it fit into the battery quadrocopter compartment. Dimension information is usually indicated in specifications of both devices.

In addition, the weight of the battery must be such that the quadrocopter, along with the battery and the connected camera, had a mass less than the maximum calculated take-off. Otherwise the balance of the device will be disrupted, and the drone will simply fall.

Number of Cells and Output Voltage

The design of a lithium-polymer battery – namely, these more often total used in quadrocopters – includes several individual battery cells included in the series circuit. it provides an increase in voltage.

The output voltage depends on the number of cells. Each of them “gives” 3.7 V. As a result, 3 connected cells provide voltage at 11.1 V, four at 14.8 V, etc.

The design of quadcopter drives budget and medium price segments implies a direct increase in capacity in depending on the supplied output voltage. The higher it is, the blades rotate faster. So if weight and volume allow battery compartment, for maximum lift is worth taking battery with large output voltage.

At the same time, it is worth considering that most quadrocopters have voltage limit that can be applied to the drives. His it is impossible to exceed.

The following indicates the number of cells in the battery. marking:

  1. 1S – one cell, 3.7 V;

  2. 2S – two cells, 7.4 V;

  3. 3S – three cells, 11.1 V, etc.

Capacity

Battery life directly affects battery life the quadrocopter in which it is installed. Measured this indicator in milliampere-hours. The higher the capacity, the accordingly, the drone will last longer in the air.

Current output

Quadcopters are resource-intensive devices, so they need “hardy” batteries. Longevity parameter is also indicated directly on the battery case and measured in speed current output.

The optimal discharge rate (current recovery) is within 20C-100C. C is a conditional parameter showing the time during which the battery can completely give back the accumulated electricity without prejudice to yourself.

So, for example, a battery with a current output of 30C can be discharged in 1/30 hours (or 2 minutes) without reducing its capacity, and with current output 60С – in 1/60 hours (or 1 minute).

Connector

To turn on the battery in the quadrocopter circuit special connectors are used. Despite simplicity designs, adapters between them practically does not exist (and those that are, can lead to energy overruns resistance). Therefore, it is important to make sure that the battery connector corresponds to that used in a quadrocopter.

Design parameters

The current power depends on the current output and battery capacity, which he is able to withstand. And it is she who is the main a characteristic showing whether the batteries in use will “pull” drives.

For example, four 10 A drives are installed in a quadrocopter every. It is planned to install a battery of 1500 mAh and 10C in it. We calculate the current consumption: 4 × 10 A = 40 A. We calculate the current, which is produced by the battery: 1.5 A × 10C = 15 A. Since 15 significantly less than 40, this battery will not work.

Among the best manufacturers of batteries for quadrocopters can distinguish:

  1. Kokam, Thunder Power. Relatively inexpensive, high quality, suitable for various UAVs;

  2. Gens Ace. Have high quality, are expensive;

  3. Turnigy Inexpensive, but relatively good;

  4. Zippy. Inexpensive, characterized by optimal quality, excellent Suitable for budget quadrocopters.

Top quadcopter manufacturers

Among the best manufacturers of quadrocopters can be identified:

  1. DJI The largest, most famous manufacturer quadrocopters. Uniquely flagship devices with rich functionality and excellent flight characteristics. The only drawback is the price. For example, the flagship model Inspire 2 in Russian stores can be sold for more than 500 thousand rubles;

  2. Syma. Manufacturer of budget, but at the same time very high quality quadrocopters, which are perfect for beginners;

  3. Husban. Another manufacturer of quality, but inexpensive quadrocopters;

  4. Parrot. Launches mid-range drones custom design and nice functionality;

  5. Walkera. Manufacturer of quality quadrocopters for amateurs aerial photography not ready to spend a huge amount of money on a model from DJI.

  6. Of course, Xiaomi is worthy of mention with its quadrocopters of the middle class, but its lineup is very limited.
