Quadrocopter for beginners: the pros and cons, how to choose

Today, popular technological innovations that can be used for entertainment or other purposes. One of them - quadrocopter - radio-controlled aircraft.

The device quadrocopter

quadrocopter apparatus depends on the class. They are similar, although some models are equipped with additional equipment, representing a complex structure. Quadrocopter includes the following components:

1. Protective case.
2. The control unit is located beneath the outer shell.
3. The base on which to place the propellers.
4. Attachment for the camera.

Quadrocopter moves around, turns and changes the pitch. The movement is provided by rotating the propellers in opposite directions. It is controlled by a remote control, in the hands of a man. Depending on the feed quadrocopter team performs motion:

• Rise occurs with screws rotating at the same speed.
• Rotated by the rotation of one pair of propellers faster than the other.
• Tilting copter possible with rapid rotation of the propeller.

Pros and cons of quadrocopter for beginners

Quadrocopter design simple and does not have a complicated and unnecessary details. The main elements - the engines. In the fall can break the screws or the frame. Manufacturers have thought through the different options and details made removable so repairs should be no problems.

Quadrocopter We have the following advantages:

1. Low-cost operation.
2. flight stability.
3. Capacious battery.

Some models fly in any weather thanks to the powerful engines. They are stable in air and cope with the wind.

quadrocopter costs up to a thousand dollars, but they are inexpensive operation. Details are available in stores and, if desired, be replaced independently, though the need arises rarely. If you like modeling, the copter can constantly improve and establish advanced components.

Capacity battery allows a long use quadrocopter. With it, move small loads. The design maintains stability in the air, which is indispensable in video.

The disadvantage is the price. Quadrocopter from a trusted manufacturer is expensive. Not everyone likes the design and management, though simple, but requires training.

Fields of application

Some hams quadrocopter used for entertainment, but it is not the only way to use them. Quadrocopter facilitate implementation and utilitarian tasks.

For application areas include:

1. Videography.
2. Agriculture.
3. Use in rescue operations.

quadrocopter often they used when shooting movies. It is indispensable, because is able to shoot from a height, to get to remote places and create incredible shots. The device is used by operators of movie bloggers, on television, or when creating a wedding video. Attaching to a special tripod camera, you remove the video from interesting angles.

Sometimes farmers use quadrocopter to control possession.

rescue services quadrocopter workers use to gain access to closed areas, to blockages and slozhnodostupnym to such places. This allows you to assess the situation and make the right decisions in difficult situations.

How to choose a quadrocopter for beginners

The market offers a huge number of models that differ in price and in characteristics. Beginners are recommended to get the average value of the model. Do not buy the cheapest, because they will quickly go out of order.

Advanced will not work, because the lack of ability to control the copter can cause loss of control, resulting in a fall and breakage.

Quadrocopter choice is based on the following criteria:

1. Number of Blades.
2. Price.
3. Dimensions.
4. Control Principle.

The more powerful model, the more the battery is loaded. Therefore, the following selection criteria - the battery.

The high capacity battery, the longer flies. As a rule, the duration of the flight quadrocopter medium price range on a single charge is about 10-15 minutes. If this is not enough, you should pay attention to the advanced devices. Install an additional power supply unit in a small complex, because the motor capacity is not sufficient to take-off.

Way out become large and powerful copter, which is higher than the cost. Thanks to improved engine, it increases the duration of the flight to an hour of battery life.

two sets of batteries can be purchased, and when one discharged - replace it and continue the flight. Do not let the loss of power in the air, because it will cause the fall of quadrocopter and the failure of individual components.

Pay attention to the type of engine. This may be a collector or a brushless motor. It is recommended to choose the first option, which has reliability and long life. Commutator motors are equipped with cell phones average price category and higher.

Brushless power plants are less reliable, but their price is lower by several times. Some models are equipped with an additional motor.

The plastic quality is important. Cheap models are made of durable material, so they vibrate excessively during takeoff. Fall copter leads to destruction of the screws.

An important factor when choosing - dimensions. They can be:

1. Large.
2. Medium-sized.
3. Small (ultrafine).

The first group are quadrocopter, used by professionals. This large vehicles with powerful engines and additional equipment, the price of which is greater than a few thousand dollars. They are rare, because for ordinary users are not suitable because of the size.

Large copter can climb to an altitude of several kilometers and carry heavy loads. Dimensions allow you to install powerful batteries, optics, and other equipment.

Medium-size devices are most common. They are easy to transport, they are placed in the bag folded. This is a pretty good option for beginners who already understand the principles of management and are able to control quadrocopter in the air.

For people who have no experience in the use of aircraft best suited small copter. They are small in size, it can fit in the palm of your hand. Moreover, such a device can be put in a backpack, glove box, and constantly carry with them.

Disadvantages - low weight and powerAnd therefore boasts a stable flight, they can not. Moreover, even a small wind is critical.

Additional options

Standard quadrocopter not equipped with a camera. Controlled by it through a special console. For a beginner this is enough. If not, then you should pay attention to cell phones with cameras.

Optimally - a device the size of a medium-sized chamber 10-12 megapixels. This is enough to get a good picture. Manage such quadrocopter possible through a smartphone, running his finger across the screen.

If the connection is lost, the unit will fall to the ground. It is better to combine, display images on the phone's screen and controlled by a special remote control.

Depending on the cost, quadrocopters equipped with cameras, Wi-Fi or fixtures for the carriage of goods. Return to the specified point on the GPS signal loss, the ability to hover in the air - useful options. Having mastered control and gain experience, choose the advanced model, and enjoy your hobbies.

Exploitation

Quadrocopter presents a danger to others.

Correct operation will extend the service life.

• Do not store in direct sunlight. The device does not tolerate fluids, moisture and other substances.
• Strong impacts lead to damage and contamination when copter should be immediately cleaned.
• Do not install additional hardware on the device.
• It is not necessary at the same time to put old and new batteries. Even power supplies from different manufacturers may have a negative impact on the unit, as the chemical composition is different from the batteries.
• Special attention is paid to the battery charging quadrocopter. Ensure correct polarity. The process must be carried out on the surface of non-flammable, and battery charging and positioned away from each other. The battery is stored outside the copter.

• Use the device only in safe places. Quadrocopter allowed to run on the roads, in crowded places, in parks or playgrounds.
• It is not necessary to run the copter in a strong wind. Depending on the model, but even the wind force of 4 meters per second - too strong for that device.
• If next to you people use models to manage, keep your distance to avoid an accident. If you notice strange behavior of the device and malfunctions, immediately stop and check flight design.
• Use a fully charged battery, because the degradation of the signal - a common cause of loss of control.
