Mini Drone with Camera for Adults Kids, 1080P WiFi FPV Camer…
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.
【✈Multiple Functions】 The mini drone can be controlled by a remote control or APP. Multiple functions include one-click 360° flips, 3-gear speeds adjustable, gravity sensing, gesture control photograph/video, path flight. These functions will provide you a fun and exciting flying experience. (Please note that the app is free and does not require payment!)
【✈After-sales Guarantee】We recommend that you take your first flight indoors or in an open space without wind. (Notes:Use outdoors may be disturbed by wind). If the drone/remote control /APP has any problems during flight, please feel free to contact us, we provide 24-hour technical support. We are responsible for the quality of our products, and we provide refund and exchange service due to quality problems.
It can prevent damage to the propeller and also prevent personal injury. It is a very user-friendly feature for beginners.
90° Adjustable90° manually adjustable camera lens to provide a wider field of view, allowing you to see the world from a bird's eye view.
Emergency StopEmergency stop function -——the drone loses power and descends vertically. In the event of excessive wind or loss of control, drone loss can be avoided.
The packaging comes with a storage bag, making it easy for you to carry all the accessories to play drones outdoors.
Users' ManualWe provide two detailed user manuals that will help you better control the drone. If you have any questions, we are always available for assistance.

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!)
