1.Quadcopter Drones vs. Fixed-wing and Helicopter Drones 1.1 Consumer-grade Drones Quadcopter drones are commonly found in aerial photography equipment and remote-controlled toys. "DJI" is a well-known manufacturer of consumer-grade drones, and its details are not discussed here. In comparison to fixed-wing aircraft, helicopters, and other drones, quadcopters have a more intuitive control mechanism and higher flight freedom. However, their flight endurance is...

What is a Racing Drone? A Racing Drone, also known as "FPV Quadcopter," is an emerging extreme hobby sport globally. While it falls under the category of quadcopter drones, it differs significantly from consumer-grade drones. Racing drones can achieve speeds exceeding 200 kilometers per hour and execute various complex aerial maneuvers, such as spiral flips, inverted flight, rapid ascent, and descent. To...

Performing drone operations during the cold winter season presents challenges for both the pilot and the aircraft. The drone's battery is particularly susceptible to the effects of low temperatures and environmental conditions. Proper maintenance of winter batteries can significantly enhance operational efficiency and prevent unnecessary accidents. Risks of Battery Operation in Low Temperatures The performance of batteries is severely affected by the...

The full name of the electronic component is an Electronic Speed Controller (ESC), commonly abbreviated as ESC. Its main function in unmanned aerial vehicles (UAVs) is to convert direct current into alternating current and control the motor's speed, much like a gearbox in a car. ESC Classification: Based on functionality, ESCs can be divided into two types: those with a Battery Elimination...

How to determine the quality of a brushless DC motor? There are several common methods: Observing the Motor's Sound: When the motor operates at low speed, you should hear a faint and continuous sound. As the motor's speed increases, the sound may gradually become louder. If you hear abnormal noises, excessive noise, or an irregular sound pattern, it may indicate poor motor...
