How we (not) found the sniper using a quadrocopter

It is a serious model of the reconnaissance drone, which can fly around the corner or climb to a height of 9+ storey houses, broadcasting live video for 12,000 rubles.



Initially, I had an idea to make a story about how with the help of this drone it is easy to find a sniper in an abandoned house. Why not? The speed with which I gained height - 3 floors in 5 seconds, the speed of horizontal flight is even higher. Flight time is 9 minutes. A 9-storey house with 20 columns of windows can have time to scan (15 seconds to lift 9 floors + 2 seconds to offset sideways + 15 seconds to lower) * 10, provided that one person controls the copter, and the second is carefully watching the contents of the picture on the subject of signs of a person / rifle.

But after several calls to my acquaintances asking “I need a rifle”, I received the answer “Lech, it’s clear that the crisis, but not to the same extent”, my enthusiasm subsided, and I focused on enhancing the flying skills and speed passing the track).

So, let me introduce you a Hubsan X4 H107D radio-controlled quadcopter with a transmitting video camera and 2.4G equipment (thanks to the Ypapa.ru store for the equipment provided).

Under the cut there is a sniper, which I did find, as well as a description of a cool quadcopter and several videos with a test for flight speed (25 mph), a 100+ meter altitude test and DIY gadgets

Remote controller
Very close to professional remotes.

Very precise control (compared to toy consoles):

• Transmits live video to the control panel with a resolution of 720 by 480
• Records video to the memory card (the video quality will be without interference on the remote control).
• You can watch recorded videos directly on the control panel.
• The range of the remote control is 150–200 meters (I flew about 70 meters, this is practically the limit of sight of the parking lights).
• Automatic stabilization system (allows you to cope with drafts in the apartment and light wind on the street, I flew even in the snow).
• Able to do somersaults (in the directions "to yourself, from yourself" and "right-left").
• Additional blade protection and 4 extra blades are included.
• Responsive management (easy to put on a target-size book size).
• Flying through the eyes of birds at a height of 17-storey building using glasses (glasses sold separately)

Points for this helicopter:

The image is transmitted to the glasses via a dedicated communication channel in real time, on the virtual glasses monitor everything that comes into view of the video camera is displayed. Due to the high refresh rate of the image and the selected video transmission channel, the image is transmitted without delays and lags.

The US military resolves the issue like this:



Beautiful video demonstrating the possibilities, incl. landing on a lotus leaf in a pond:



Speed ​​test on the car from foreign colleagues:



Test height in Moscow:



The Germans raised their Habsan 100+ meters:





Batteries last for 8-12 minutes of flights, so I advise everyone to buy 2-3 more spare batteries and chargers in order to fly 30-40 minutes

Craftsmen insert high-capacity batteries:

DIY

Quadcopter disassembled and assembled in 5 minutes. Here is what's inside:









I came across an interesting video on the Internet from American and Chinese homemade products about Habsan 4x FVP:

Conclusion

If you already have basic skills (don't hit walls or cats, don't confuse top and bottom, right and left, can calibrate the remote, you can fly around the room with people without hitting anyone, etc.) of the drone control (and for that the light version of the Hubsan X4 2.4G ), then in order to learn how to operate on a professional remote, learn to fly around the camera (FVP), and take the next step towards managing drones that cost more than $ 500, the model I described is ideal.
And welcome to the club pilots drone.
