In this article, we will talk about what quadrocopters are and what they are. Let’s talk about which ones are suitable for beginners and professionals, and touch on the features and limitations that are best known before purchasing and the first flight.
How do quadcopters work?
Quadrocopters are aircraft with four propellers. They are battery operated and controlled by a smartphone or remote control. The basic principle of operation is to adjust the rotation of the screws, and advanced models are stuffed with additional stabilization improvements and other sensors.
Some models have useful features such as automatic obstacle avoidance and hovering. Quadrocopters differ in design, functions, size, purpose, control method and additional features. All this also affects the price – the more complex the filling, the more expensive the copter.
Drones can be used for training, stunt and shooting. Training courses are designed to withstand the mistakes of a novice pilot. Stunt ones fly more sharply and faster, while filmmakers have cool photo and video capabilities due to the built-in camera.
In the beginning, it is better to buy a small copter in order to learn how to operate it from the remote control and not harm anyone.
What kind of quadcopters are there?
First, you must select a device. Beginner drones will fall and crash into obstacles anyway, so they usually have small dimensions, protection and a spare set of propellers. Small devices are also suitable for children, they can fly indoors.The control of such copters is greatly simplified and is designed to practice basic skills. There are only the most essential functions – takeoff, stabilization, landing and automatic stunts. In order to better understand the functions of the selected model – see the reviews for a particular model.
The choice of medium-sized drones is much wider – there are training, stunt, filming and even home drones. From the nuances – stunt and racing copters are distinguished by bright colors, and filming drones have an advanced camera with gimbal and stabilization system. There are also professional models with a large load capacity, but they are designed for highly specialized tasks.
What do you need to know before launching a drone?
Before turning on the aircraft, understand the instructions, read the specifications and learn how to operate the aircraft. It is necessary to clearly know the purpose of each button on the remote control. Be sure to connect the aircraft to your smartphone if available. Open the app and look at the options – there they are usually presented in more detail. In addition, the drone may not find GPS without connecting to a smartphone, and then it simply will not take off.
Fully charge the aircraft before flying. In some advanced drones, there is a self-control mode – if the device is not used, its battery goes into storage mode, having previously charged up to half. As a rule, in the models by default all possible restrictions are included and there is a training mode for beginners, so the aircraft “does not want” to fly indoors or too high. Do not forget about the restrictions under the law of the Russian Federation, because a drone is an unmanned aircraft, and its owner is an external pilot. Models weighing more than 250 grams are subject to mandatory registration .
What do you need to fly a quadcopter?
A smartphone and / or remote control are used for control. The remote control usually has two levers, the left one is responsible for moving the aircraft vertically (up, down and turning left and right), and the right one is responsible for horizontal control. The presence of other functions and the corresponding buttons is determined by a specific drone model, so you need to study the instructions for it. There are buttons for shooting, landing home and performing tricks, the difference can even be hidden in the way you press the button – long and short presses can be responsible for different actions.
Typically, the joysticks are “spring-loaded” in the middle, and the drone straightens out horizontally and stays at the height you set. Also learn about the copter control modes. The most common modes are Normal, Sport and – the most difficult – Manual. It allows a professional pilot to manually control the device, without stabilization systems. Most often, the copter creates its own Wi-Fi access point, it is to which you need to connect your smartphone. Although sometimes there are old ways – with a wire connection. The functionality of the application depends on the model of the drone, but usually you can watch the picture from the camera, monitor the state of the copter, control modes, functions, overflight points and restrictions.
To prepare for the flight, you can use the mobile simulator on your smartphone. Some manufacturers make special simulators for “native” remotes. Mechanical controllers can also help, although the touchscreen is unlikely to give the feel of real flight.
When and where can you fly a drone?
The copter can fly during daylight hours within the line of sight. Avoid electromagnetic interference and other obstacles as much as possible, select the field away from trees and power lines. Do not launch the drone during bad weather – fog, wind, rain. First, fly the drone in beginner mode. Do not set additional parameters until you feel that you are confidently operating the device.
You cannot fly over strategically important objects or airfields, as well as in crowded places, so as not to injure anyone. It is forbidden to shoot mass sports events and climb to a height of more than 150 meters. To see the locations where you can fly, visit the flight plans website . It is recommended that you check your seat on such a site before flying. Actual data specifically for your area will have to be clarified.
Getting ready for the flight
You have read the reviews, charged the battery, learned from the simulator, selected and checked the area, the weather is good.
Now you can turn on the remote control, and then – the quadcopter, this is necessary in order for the equipment to synchronize. Calibrate the drone – it needs to find as many GPS satellites as possible and determine the exact coordinates. Without them, the drone runs the risk of not returning home. Usually, the calibration takes place automatically, the main thing is to prevent error messages and check the correctness of the obtained coordinates.
When flying for the first time, stand behind the aircraft. You can determine the backside by the green lights, and in front – by the red lights or by the camera. Try to slightly raise the drone and land it. Raise the copter by 0.5-1 meters at once, as otherwise it may get caught in an air vortex near the ground.
Always keep the aircraft in line of sight and do not turn the front of the aircraft sideways or towards you. Select the starting and ending points of the flight and try to navigate the aircraft to the desired point without turning it around. Then repeat the same, but with a turn. Take your time and do the figure eight.

If you forget which side the nose is on, swing it forward slightly. Make sure that the aircraft does not fly too far and that there is enough charge to return to the starting point.
Quadrocopters can be useful helpers or interesting entertainment for you . For some it is a toy, but for others it is a professional filming tool . The main thing is to understand, learn and choose the model you need. And don’t fly far until you gain experience.
