Today, drones are getting easier and more fun to fly. When it’s becoming a trend for drone companies to make consumer drones for more common users, drones have transformed from a geeky enthusiasts affair to a full-on cultural phenomenon.
If you are completely new to UAV, or you just got yourself a new DJI drone, there are quite a number of things you need to know about them, but you certainly won’t be wrong to start with the features below. Let's check them out!
1. How do drones work?
· Basic components
To understand how drones work, the first thing you should know is the basic components of drones and how these parts work together.
TX – The Transmitter
It means your remote controller. RC enables you to control the aircraft from a distance.
ECS – Electronic Speed Controller
The electronic speed controller controls the rotational speed of the motor.
RX – The Receiver
It is an electronic device that receives radio waves from the transmitters and converts the information carried by them to a usable form.
· Principle of Control
The movement of drones relies on the pulling force generated by the rotors. When the rotor is rotated by the engine through the rotating shaft, the rotor applies the acting torque to the air, and the air inevitably acts on the rotor (or anti-torque) at the same time. And with the equal and opposite reaction torque, the rotor transmits this reaction torque to the aircraft. If no measures are taken to balance it, the reaction torque will make the aircraft rotate counter to the rotation of the rotor. In other words, spin occurs. So that's why on a quadcopter, the propellers are usually used in pairs.
