Quadcopter mini foldable selfi drone


When the Air Selfie project, then at the crowdfunding campaign on the Kickstarter platform, was unveiled, I was very cautious. Too small, without stabilization of his camera. The project was funded, he fell behind as always, but it is now available for purchase. What is it really worth? Here is the result of the tests. Note that this device was given to us by the Bang good store. As usual, tell us if you think that practice has influenced our judgment. Note that an Airselfie2 is out, available in France. It's the same, exactly as this Air Selfie. 

Owner’s tour
The Air Selfie surprises by its featherweight, 61 grams on the scale with its battery. Anyway, there is no choice, we cannot remove it is integrated and not removable. The device measures 6.8 x 9.5 x 10.6 cm. It's slightly wider and thicker than a smartphone, and shorter.  Impressive especially as the 6-blade propellers are built into the hull, made of aluminum. They are animated by brushless micromotors. At the front of the camera is the lens of his camera. At the back is placed a micros connector. On the sides, they are ventilation grilles. Under the Air, Selfie is housed the on / off button, an IMU chip that combines a gyroscope and an altimetry barometer, and a vertical camera.

 Before taking off?


The Air Selfie must be recharged via the micros connector. It only takes one USB port that delivers at least 2A for the load to be operational. It takes about 25 minutes for a full charge. The version I tested comes with a portable battery, type "Power Bank". It has an external micros connector, but it also allows you to host the entire Air Selfie! Once slid inside, the charge starts automatically. 

The settings

Long press on/off button to turn on the Air Selfie. It emits a triple beep - in the absence of a diode, it is the only way to know that it is on. It appears in the list of wife access points. Once connected, launch Air Selfie. The top-right icon allows you to calibrate, select photo settings, determine control jitteriness, and get a summary of component versions. The settings of the camera? Let's say they are sketchy: you can determine a delay before the triggering of a photo and take several snapshots. That's all. Back to the main menu which gives access to 3 driving modes and the photo and video gallery.

Selfie Beginner mode

Why selfie? Because the camera is flying with the camera facing you. Why beginner? Because orders are given by pressing virtual keys on the screen. The interface is presented vertically, and the video return compressed in a square that tightens the image.  It's not really nice. The latency is high, and the number of images per second displayed on the smartphone screen is low. An icon makes it possible to start the recording of a video, another one cuts the engines in urgency. To take a picture? No icon, just touch the image. 

What should be done?

The principle of taking off the Air Selfie is to launch it by hand! Very slowly, to make him leave the palm of the hand. Astonishing, but it works pretty well, it detects the absence of the hand and stays in the air. Finally.it stays more or less in the air. Because maintaining the altitude, with the help of the barometer altimetry, is not really effective, it's the least I can say! The Air Selfie goes down a good meter, sometimes more, and goes back up. But not always. In this case, it's up to you to push the throttle. 
So this mode "Selfie Beginner"?
It allows you to go up, down, turn right, turn left, rotate right, turn left. But to move forward and back? It's not planned. As the stationary is non-existent, this absence is synonymous with a crash in the minute after take-off! The Air Selfie does not always stop during a crash, it is up to you to cut the engines with the virtual key. This first flight is very disappointing! Switch to "airSelfie Motion Control" mode. The presentation is the same, but the interface shows a virtual pad with 4 keys: up, down, right rotation left rotation. For advance, recoil, slide right and left, you have to press the screen and tilt the smartphone. Automated stationery is still inefficient, but driving is a little easier.

How to Choose Your Mini Drone

This is not new, the drone has seized the sky at high speed for some years. You just have to look up to see how fast it is changing. If driving a drone in France is like pure leisure, more and more professionals from all sectors adopt the aircraft in turn. The family of drones is relatively large and lists several members to his credit. The mini drone is one of the favorite little ones because of its maneuverability.
The small size of the mini-drone allows most neophytes to use without deep learning. It is also a recommended equipment before moving towards a larger drone. But what exactly is a mini drone, and above all how to choose It.? Since the market continues to offer new models, it is relevant to take stock together. 


Mini drone for maximum pleasure
The mini FPV drone is different from the more conventional drone. But small size does not imply fewer sensations. Indeed, its reduced size allows it to sneak with ease where you want. In addition to its simplicity of piloting, the mini-drone is particularly adapted to the younger ones. Indeed, whatever the age of its pilot, this mini aircraft can be remotely controlled in a garden or a closed room. Depending on the model chosen, this particularly identifiable flying object will be more or less stable. This is why it is necessary to seriously inquire about each feature of the mini drone before buying it. A good choice will help maximize driving pleasure.

What to do with a mini drone.
Before orienting you towards this or that category of mini drone, it is important to understand the usefulness of such material. Answering this question is difficult, as each brand, each model has a particular use. In most cases and depending on the sector, the mini-drone will offer a variety of application.
The French army also uses mini drones, with a view of recognition in particular. It should also be noted that the massive use of the drone tends to reduce the exposure of men to a dangerous situation. Another case, that of audiovisual production; with the onboard camera located on the mini drone, it is possible to film beautiful images for cinema, television or advertising. But professionals are not the only users of mini-drones! Individuals love it more and more, for the simple pleasure of driving to film or photograph aerial views.

Buy a drone what should you watch.
Difficult to end up in this jungle that is the flying drone market. Like many new technologies, the development of this flying world is realized at the speed of light. If the regulation around the drone tends to tighten, several models flock by offering more and more features. The fervor generated around the FPV drone experience is not unrelated to this general craze.
It is in this sense that manufacturers are always pushing their ingenuity to offer enthusiasts equipment that lives up to their expectations. Thus, mini drones of all kinds are born, an additional difficulty for the pilot in terms of choice. When one wants to select the best dome for its own use, there are several parameters on which it is essential to support one's attention.

The main advantage of a mini drone is the presence of an HD camera for aerial photography. Today, it is possible to find mini-drones capable of recording images in VGA, XGA, HD 720p, HD 1080p or 4K. Do not turn to the best possible definition, this one may not be for you. Also, whether it's a Parrot mini drone or a DJI drone, a brand will not offer the same rendering with the same feature. In addition to the mini camera, pay attention to the field of view and stabilization. These elements are essential so that the recording of your video is sufficiently qualitative. Whatever happens, know that a mini drone, unfortunately, cannot offer performance as strong as a professional drone. In addition, mini-drones have a relatively small autonomy a, it is advisable to bring you extra batteries to not shorten you’re driving prematurely

Should we opt for a pre-mounted mini drone or a mini drone to make yourself?
Another possible specificity, that of the assembly of the affordable mini drone. You should know that FPV drones are listed in two categories; loans to steal (RTF) or loans to binder (BND). In this case, it is above all your level of experience that will determine the most suitable equipment. The beginners will thus be more willing to turn to a   mini RTF drone. It's a fact, build your camera drone involves some skills that beginners will have trouble performing. A mini drone RTF is a better solution since it allows you to do your hand on his piloting before understanding the assembly of his pieces. This will ensure you have a good flight experience before moving to another more complex model.
