Mini Drone for Kids
The sky is full of dreams. Let our drones be your dream catcher.
Everyone should have easy and inexpensive access to the flying dream. That’s why we dedicate ourselves to creating high-tech, affordable, and fun-to-fly drones.
Since 2014, Holy Stone has become the best choice of entry-level drones for beginners and drone lovers. More than 5 million customers have enjoyed flying and captured great life moments with their Holy Stone drones.
Straightforward Operation: With the help of One-Key Start and Altitude Hold, the drone will take off and hover at a certain height. In the Headless Mode, you can operate the drone easily without the loss of direction. Emergency Stop can prevent most urgent situations. Flight has never been this easy.
More Fun Features: The drone can be Tossed to Launch, it can perform stunts like 3D flip, Circle Fly and High-Speed Rotation. You can customize a flight path through the APP and the drone’s flight path will follow the one you draw. What’s more, High and Low-Speed Modes make the drone fit with both experienced and novice pilots. The joy of flight is endless.
720P HD FPV camera: The mini drone is equipped with a 720P HD FPV camera including adjustable angle, which captures high-quality video and clear photos by specific gestures, as well. The WiFi Real-Time Transmission can broaden your view. Photography is easy as pie.
Two Batteries Double Fun: 2 Modular Batteries extend your flight time and guarantee enough time for you to enjoy the splendid flight. Moreover, the modular battery is much easier to change and far safer to charge. Free flight without endurance anxiety.
Mini and Portable: You can take this Pocket-Size drone to wherever you want to go, which only takes tiny space in your pocket or bag. The propellers are completely wrapped by the protection guards. Kids won’t be hurt by running propellers. Taking it to the party, school, fishing, hiking, or long journey would be an extremely great idea. Seize every wonderful moment.

Product Description
【✈1080P Camera Lens & FPV Function】The kids drone with camera is equipped with a 1080P HD 90° manually adjustable camera lens to provide a wider field of view, allowing you to see the world from a bird's eye view. With your phone /iPad connected to the drone WIFI, you can watch the wonderful scenery in real time. Photos or videos are automatically saved in your phone's album, which you can easily share share on social media.
【✈3 Batteries】In order to increase your flight time and get more fun. We upgraded the battery configuration. The small drone is equipped with three 1,800mah rechargeable batteries. Each battery provides approximately 10 minutes of flight time. In total 30 minutes endurance. Note that more flips and frequent flight altitude changes will reduce the flight time per battery.
【✈Easy to Use】The camera drone has user-friendly features that make it easy for kids or beginners to control. Just press the one-click take off/landing button to fly. Compared with other drones of the same type, we have added the bottom camera lens and optical flow positioning function, which allows the drone to maintain at a very stable altitude and easy to be controlled. Headless mode, emergency stop, and propeller guard all make it easy for beginners to control this drone.

Simplified UAV Design for Students
Every year, hundreds of students participate in UAV design competitions such as AIAA Design Build Fly or SAE Aero Design: Each team has less than one school year to design, build, and fly an airplane, ranging from a small remote-control airplane to a large autonomous vehicle capable of flying itself and of dropping packages (or even smaller airplanes) that land on a target.
For students without an aeronautical engineering background, who are majoring in fields like mechanical engineering or computer science, many questions naturally arise, such as:
• What wing area is necessary for good flight characteristics?
• How are the optimal aspect ratio and wingspan determined?
• What is a realistic weight goal for an aircraft of this size and engine power?
• How is the best airfoil selected?
• What is the ideal length for the tail cone / tail boom(s)?
• How are the sizes of the tail fins and control surfaces calculated?
• Fewer ribs require a thicker spar, so… What rib spacing will lead to the minimal total structural weight of the wings?
• How can a wing spar be designed that has the required strength and stiffness as well as minimal weight, while also allowing the wing to be easily disassembled into multiple sections for transportability?
• What electronic components are typically found in an RC airplane? How do they work? How can their required capabilities for my airplane (e.g. power and torque) be calculated?
I have mentored multiple groups of students. This book collects my answers to these questions, mostly consisting of step-by-step analyses that use methods and best-practices from the aeronautical industry, from engineering textbooks, and from the expertise of RC airplane builders and ultralight designers.
This book is also a great resource for any hobbyist who wants to design and build an RC airplane while doing at least a little bit of engineering beyond “That looks about right” or “I’ll just copy the way it’s done in similar airplanes”. The simplified analyses in this book can be done by anyone with an understanding of high-school physics and will allow for an airplane that has minimal weight and minimal drag while being able to perform a desired mission (i.e. carrying a desired payload at a desired speed, and being able to take off and land on a desired runway length and to climb out at a desired angle).
The same principles apply to designing an airplane that can carry one or more humans… but, for that, I recommend Daniel Raymer’s Simplified Airplane Design for Homebuilders, a terrific book that was my main inspiration for writing Simplified UAV Design for Students. (In other words: Please do not trust your life to a vehicle that was designed using the simplified equations in my book!)
