A quadcopter, often called a drone, is a special kind of flying machine with four rotors. These rotors are like the quadcopter's engines, helping it stay steady and move precisely. Here are the key parts:
Visible parts include the frame, motors, propellers, battery, remote controller, propeller guards, gimbal, camera, and the remote ID module.
Inside, there are hidden parts like Electronic Speed Controllers (ESCs), flight controllers, radio transmitter and receiver, a GPS module, and an integrated remote ID.
All these parts work together, making the quadcopter fly smoothly and with great control. It's like a well-orchestrated performance in the sky.
【Frame】
Think of it as the quadcopter's skeleton, the sturdy structure that holds everything together. When we talk about quadcopters, we're talking about those drones with four arms, and that's why they're often called "quadrotors" or "quadcopters." Now, drones, come in all shapes and sizes, and depending on the frame, they can be divided into Fixed-wing drones and Rotary-wing drones.
Rotary-wing drones, they're the ones with rotors. And in the world of rotors, we've got helicopters, which usually have one or two big rotors on top, and then we've got multirotor drones. Multirotor drones are the real stars of the show here, and they can have three, four, six, or even eight rotors. But when most folks talk about quadcopters, they mean those drones with four rotors, and those are the ones we see most often in our daily lives.
Foldable Quadcopter
Now, let's take a closer look at quadcopters. The foldable quadcopters have become the mainstream choice nowadays, and it's easy to see why. Their foldable design adds a remarkable level of convenience, allowing you to effortlessly carry them around and stow them away when not in use. Models like the HS190 (a mini toy drone), HS440 (a beginner drone), HS360S (ideal for hobbyists), HS600 (suited for adventure seekers), and the HS720 series are all excellent examples of foldable drones.
Non-foldable Quadcopter
However, on the other side of the coin, we have the non-foldable quadcopters, which shouldn't be overlooked. Most of them boast sleek, streamlined designs, the aerodynamic profiles, granting them a significant edge when it comes to battling the wind as they soar through the skies. This, combined with their robust construction, results in outstanding stability and dependable performance across a wide range of conditions.
Take models like the HS110G, HS110D, and HS700E, for instance. These drones shine as excellent choices for locales where windy conditions are the norm.
【Motors?】
You've got four of these little powerhouses, one at each corner, driving those propellers. The motors can be brushed or brushless, with brushless motors being more common due to their efficiency and durability.
Those spinning blades on top of each motor, they're what lift the drone into the sky.
【Battery】
This is the power source, typically a lithium-polymer battery, keeping everything charged up.
【Remote Controller】
The pilot's essential tool， is a handheld device equipped with joysticks for sending precise commands to the drone.
【Propeller Guards】
Now, these are extra safety measures, often seen on indoor mini drones. They come in various forms and protect young or novice pilots from accidents.
【Gimbal】
If you're into photography or video, you might have a camera drone with Gimbal. Such as HS720G, and HS600 are 2-axis Gimbal drone, and HS720R is 3-axis Gimbal drone.
【Camera】
Most quadcopters are camera drones. On platforms like Amazon, they're sometimes called FPV drones, short for First Person View Drones. However, among drone enthusiasts, "FPV" is often reserved for describing racing drone or freestyle drones, like DJI's XX models.
【Remote ID】
If your drone isn’t a Standard Remote ID drone, you could add an external Remote ID broadcast module.
【ESCs】
Electronic Speed Controllers (ESCs): These are like the drone's throttle managers, hidden beneath the frame, responsible for regulating motor speed and direction.
【Flight Controller】
The flight controller is the brain of the quadcopter. It processes data from various sensors and user input to stabilize the quadcopter and execute flight commands. Modern flight controllers often include accelerometers, gyroscopes, barometers, and other sensors to provide stability and position control.
【Radio Transmitter and Receiver】
These wireless communication devices bridge the connection between your remote control and the drone.
【GPS Module】
It's the navigator, providing location data and aiding in navigation.
【Built-in Remote ID】
If your drone is a Standard Remote ID drone: it will come with a built-in Remote ID broadcast.
Drones are not just fun flying toys — they are powerful STEM learning tools that combine science, technology, engineering, and mathematics. By understanding the main parts of a drone, such as the frame, motors, propellers, battery, sensors, and flight controller, kids can learn how real machines are designed and how different systems work together. This kid-friendly beginner guide explains drone components in a simple and educational way, helping young learners build curiosity, problem-solving skills, and a strong foundation in STEM.
1. Structural System
In the first years of life, babies learn mainly through their senses. Carefully chosen sensory toys channel all that touching, seeing, hearing and mouthing into safe, structured exploration and support early brain wiring.
Includes: rattles, cloth books, high-contrast visual cards, crinkle toys, bath toys, soft sensory balls, teething rings.
Age focus: 0–2 years.
Personality: curious little explorers who reach, grab, stare and react strongly to new sounds, textures and lights.
Typical scenes: tummy-time on a playmat, stroller rides with a rattle, floor blanket exploration, bedtime wind-down with soft toys.
Value for kids: builds early visual tracking, grasping, cause–effect understanding and whole-body awareness.
Supports developmental needs: sensory integration, secure exploration, hand–eye coordination and basic emotional soothing during 0–2 years.
Keywords: sensory toys, baby rattles, cloth books, high-contrast cards, early development.
2. Power & Propulsion System
For many children, a favourite plush becomes a “portable piece of home”. It supports emotional stability when they face separation, new environments or strong feelings.
