One of the most compact and affordable Spark drone from the Chinese manufacturer DJI shows problems during operation. At least 14 users complained that the drone freezes during the flight, and then falls to the ground with a stone. Some drones fell from a small height, so they were able to recover and study diagnostic data: no technical problems were found. Others simply drowned in reservoirs, fell in dense forests or mountains. One of the users even shot a video, as Spark, having lost control, continued to fly, shooting his rapid escape. This problem was also confirmed by a number of independent tests. Experts believe that users themselves are often to blame for accidents who incorrectly configured proximity sensors to the ground. As a result, the drone inaccurately interpreted its position and turned off the engines. However, some pilots shared their flight logs, where there was no information about some mistakes that might have caused crashes. Recall that last year GoPro Karma users faced a similar problem and experts explained it to battery malfunctioning. But, given the impeccable reputation of DJI, which specializes in producing drones, Spark accidents have received more resonance. While developers are trying to figure out what happened. Perhaps the reason really lies in some kind of internal defect and the manufacturer will have to recall this model at a cost of $ 499 or it will be enough to update the firmware.
