Tencent Digital (John) announced in May last year that GoPro announced the launch of its own brand of unmanned aerial vehicle Karma. This marks GoPro's official entry into the field of aerial drones and direct competition with the industry leader DJI. After a long wait of more than a year, this drone finally met with everyone. The GoPro Karma drone has a four-axis folding structure and is a small-sized drone. The remote control part adopts the design of a flip touch screen, equipped with a 5-inch 720P resolution display, and two joysticks can control the flying attitude of the drone. The Karma drone is equipped with a 5100mAh battery. It takes 1 hour to fully charge and it can take up to 20 minutes for a single charge. The Karma drone itself does not have a camera, but it needs to be used with a Hero 5 or Hero 4 motion camera. The Karma drone will be listed in the United States on October 23 (domestic will be listed early next year), priced at 799 US dollars (about 5328 yuan), and the domestic retail price after listing is 6498 yuan, Karma no Man-machine standard host, handle, stable head and backpack. Hero 5 Black Edition is priced at US$399 (approximately RMB2,660), Hero 5 Session is priced at US$299 (approximately RMB1994) and will be available in the United States on October 2nd. The domestic market will also be used by e-commerce companies. Sites are listed simultaneously. The combination of Karma and Hero 5 Session is priced at US$999 (approximately RMB 6,662), and the Hero 5 Black Edition is priced at US$1,099 (approximately RMB7,329). Here's a look at the evaluation of this drone by major foreign media. TheVerge The advantage of Karma is ease of use, and in most cases it is very easy to operate. It has an automatic takeoff/landing function, an "easy" flight mode and some semi-automatic modes. After the remote control is turned on, the upper part is the screen, which you can use to manage the settings, change the flight mode, and watch the pictures taken by the drone in real time. The lower part provides the standard rocker, the left rocker controls the altitude and direction of flight, and the right controls the tilt angle of the drone in all directions. There are two buttons between the joysticks, one for starting/stopping the motor and the other for automatic landing. There is also a control button on the shoulder of the controller and a dial for adjusting the angle of the camera. Unfortunately, Karma did not follow the model. For GoPro, a company that specializes in producing self-portrait cameras, it lacks the automatic follow-up mode. Life, Karma's battery life is only about 20 minutes, you can see the current remaining power at the top of the screen. With the depletion of power, this power indicator will gradually change from green to orange and finally to red. When the remaining flight time is less than 4 minutes, the unoccupied space will automatically return to the takeoff point. Karma has a modular design and comes with a backpack. Its four rotor arms and the landing gear on the bottom are all foldable. In the folded state, Karma occupies about half a meter. GoPro also stated that rotor arms and rotors can easily be replaced in the event of damage and can be completed within seconds. Techradar As an aerial drone, Karma is moderately priced and can take a stable image at a height of 1,000 meters. The maximum speed is 54 kilometers per hour. The 3-axis stabilization head can be used to ensure stable and clear images. The entire drone adopts a black-and-white color scheme, and the matt black landing gear plays a good buffer role when the aircraft lands. There is an indicator lamp below each propeller arm. The first two indicators are green, and the latter two indicators are red, which is convenient for the user to judge the direction of the head. However, it is still difficult to distinguish under strong light conditions. The control aspect is different from that of DJI Phantom 4 and does not require watching the real-time image through the iPad. The remote control of the Karma drone has its own display screen and can synchronously transmit video signals with a resolution of 720P. In terms of portability, the Karma drone can be easily folded and put into a backpack. It is ideal for outdoor shooting. The propeller can also be stored separately for transport safety. The weight of the whole machine is only 1006 grams, and the folded size is 117 x 224.3 x 365.2 millimeters. In addition to the actual flying ability, the 3-axis head for stabilizing the camera can also be removed and connected to the handheld base for user-friendly shooting. The handheld device has a built-in battery that can power the cloud platform and can also charge the GoPro at the same time. Karma's stable head is installed at the head position and can be adjusted vertically by 90 degrees. The head itself cannot move horizontally, but you can rely on the right side of the drone to adjust the direction of the drone to control the horizontal direction of the shot. In actual experience, the Karma drone takes off smoothly and can be viewed on the 5-inch screen on the remote control. The pitch/yaw joystick is very sensitive and controls the drone like a game console. For beginners, a takeoff/landing button can make it easy for rookie users. Even at the top of a mountain with strong winds, Karma can hover steadily and maintain a clear video transmission. In past evaluations, some drones always have problems in this environment. The remote control is very compact and does not have an external antenna, but the maximum brightness of the monitor is 900 nits, which can satisfy most weather conditions, but if it catches up with the very strong sunshine, the brightness of the display is still somewhat inadequate. Due to the addition of the 3-axis anti-shake pan/tilt, we encountered windy weather in actual tests, but the shots were still stable and clear. Although you can only get 20 minutes of battery life on a single charge, you can increase battery life by extending the battery life. There is enough space in the backpack to accommodate the extra battery. The remote battery can last 4 hours and the charging time is 2.5 hours. The built-in battery of the shooting stick can last for 1 hour and 45 minutes and the charging time is 2 hours. Engadget After a long wait, GoPro finally released its own Karma drone. As we would expect, the Karma drone has a four-axis compact design with a sleek profile, the propeller arm can be folded, and can be easily folded into the included backpack after folding. We first met its true colors in Squaw Valley, California. At the launch of the new drone, GoPro also released two sports cameras, Hero 5 Black and Hero5 Session, which can be used together with Karma drones. The Karma drone operation is very simple, using a traditional joystick controller, the user interface is very user-friendly, easy for beginners to start. GoPro stated that they do not want to complicate the operation of the Karma drone, which is why the menu on the remote control is also very simple and intuitive. From the menu, you can set the drone from point A to point B. The complicated switches and plugs on many professional remotes cannot be found on the Karma remote. In addition to the two joysticks, there are only two buttons on the front of the remote control. One is responsible for taking off/landing, and the other one can be used for one-stroke return. After 10 minutes of actually experiencing the flight, Karma drone left a deep impression on me. I think the biggest advantage of this drone is that it is very easy to use. It can be used with GoPro Hero 5 Black camera or smaller in size. Hero 5 Session can be used in conjunction with, or can be installed previously purchased Hero 4, can save some money. Says the price, although not very competitive, but it is also within the acceptable range, Karma drone alone price is 799 US dollars (about 5328 yuan), with Hero 5 Session and Hero 5 Black camera prices are 999 US dollars (about 6662 yuan) and 1099 US dollars (about 7329 yuan), is expected to begin shipping on October 23 next month. Pcmag GoPro’s Karma drone has been brewing for a long time and has repeatedly hinted that HD cameras with multi-rotors will be released and will be officially released in 2016. The newly released Karma drone does not have much of an appearance, and its portability is that the four rotor arms can be folded so that it can be easily carried in a backpack. The four direction indicators under the rotor arms are bright and are easily visible in the deep blue sky of Nevada. These are not bright spots. The most interesting thing is Karma's remote control. Compared to the DJI Phantom 3, which costs $599.99, Karma's remote control comes with a 720p-definition screen. The flying experience is like playing video games. Press and hold the one-button take-off button in the center of the remote control. A countdown prompt will appear on the screen. After a few seconds, the propeller starts and Karma starts to take off automatically. At this time, the screen will switch to the perspective of the drone camera and transmit real-time video images. The knob of the remote control adjusts the shooting angle of the universal joint. By gently pushing the right stick, Karma will release the hover mode, but even if you quickly push the stick, the drone will execute the command smoothly, which is very conducive to stable shooting and flying in unstable wind conditions. But if you want Karma to do some quick manoeuvres it is not possible. After about 4 minutes of test flight, the battery power dropped by 20%. Since there was no strong wind, I could not experience the extreme flight performance of this drone, nor could I change the parameters of the flight control system. During the flight, the video signal transmission is very smooth, and the camera also recorded a 1080p format 60 frames per second video. When landing, you can use the "one-click return" function, or you can manually operate the landing. I tried to land manually, but GoPro's staff has been watching me nervously, and it is too small to call me the old driver. GoPro also stated that the App for the App will also be coming soon. Your friends can connect with Karma remote controllers to view real-time video of Karma's flight, and even adjust the angle of the UAV's head with a program. Although this app is not yet officially released, because the connection is a direct wireless connection, the quality of the transmitted picture is guaranteed and should be the same as the picture seen on the remote control. Mashable Nick Woodman, CEO of GoPro, in Squaw Valley, Calif., said the company’s launch of Karma will be more than just a drone. Indeed, Karma's stable pan/tilt can be connected to GoPro Hero 4 or Hero 5 series sports cameras, while the pan/tilt can also be disassembled and mounted on a handheld stand to form a handheld shooting platform. Karma sells for $799 (about RMB 5328) but does not include a camera. If you have purchased GoPro Hero 4 or 5 earlier, you can save some money. Karma's sleek design and remote control are also very simple. Compared with the professional aircraft's remote control, Karma's remote control is more simple and easy to use. It is very suitable for beginners, does not need to adjust complex parameters, and has many automation functions during the flight. use. Normally, the drone's remote control needs to be installed on a tablet or mobile phone to be able to view the returned real-time image, but Karma's remote control comes with a 5-inch screen and a polarizing filter is installed to allow the user to The drone-observed picture is clearly seen under strong outdoor light. Karma's battery life is 20 minutes. It is possible to extend battery life by adding batteries. The remote controller can be used for 4 hours at a full charge. Karma's propellers are also detachable. If they are accidentally damaged, the installation is very simple. Karma's wind resistance is very good and the driving force is very good. GoPro claims that it focuses on the flying experience, especially for beginners, and of course, if it is an old driver, there are many advanced features that can be used. latest news According to the latest news on November 9, GoPro announced that it recalled Karma drones that had been sold since October 23, and recalled 2,500 vehicles. The reason for this is that some of the Karma drones lost their power during the flight in rare cases. However, no personal injury or property damage has been caused so far. Users who have purchased Karma drones can return their equipment directly to GoPro, or they can return them to their distributors for a full refund. However, GoPro will not replace new equipment for users, but will re-sell after solving the problem. GoPro CEO Nicholas Woodman said: “The security issue should be the first place. Currently only a few Karma users have encountered this situation during use. We launched an investigation and quickly recalled all sold Karma drones and provided A full refund will be given, and we will also work closely with the US Consumer Product Safety Commission and the Federal Aviation Administration of the United States. We apologize for the inconvenience this brings to consumers and will take steps to streamline the return process. ." to sum up If it is too early to say that Karma is a major rival of DJI, for the first time in the field of drones, the Karma drone has a lot of eye-catching features and features, but there are still many places that are not perfect, such as The Passenger App has not yet been officially released. Advanced features such as automatic follow-up shooting and automatic obstacle avoidance have not yet been added. In addition, just shortly after the release of Karma, Dajiang Mavic Pro made its debut, apparently as an effective weapon for Dakar to deal with Karma. Although it uses a folding design, Mavic Pro can be folded into a bottle of water, and it is even lighter. Compact, it can be carried directly into a purse or a pocket of a garment. In contrast, Karma needs to be packed into a professional backpack. Functionally, Mavic Pro also added automatic avoidance obstacle function. Although the price is slightly higher, it has a built-in camera. This way, Mavic Pro is cheaper than Karman+Hero5 Black. advantage: The portable, collapsible design occupies a small space, is equipped with a handheld shooting stand, and flight and video shooting are smooth. Disadvantages: The screen brightness of the remote control cannot be clearly seen under strong light, and it lacks functions such as following shooting and automatically avoiding obstacles. 48V Desktop Switching Power Supply 48V power supply are Anti-jamming performance, and reliable performance.DC ripple is small, high efficiency.Insulation performance,high electrical strength.
