Network exposure of DJI UAV design flaws DJI customer service: signal difference into attitude mode caused

Recently, Mr. Lin, a drone consumer in Wenzhou, posted through his personal social platform that "DJI Yu 3 may have major design defects." The upstream news reporter ([email protected] of the newspaper mailbox) saw in the online post that DJI technicians analyzed this and said that the flight accident was caused by the improper operation of the pilot (referring to the drone consumer). But Mr. Lin did not recognize and said: "As long as I delete Weibo, you can compensate me for a gift, it is really a shame that they came up with it." ”

Netizens posted screenshots of "DJI Royal 3 design may have major flaws"

On April 6, the upstream news reporter called the DJI service hotline, and the customer service responded: "There are cautious flight tips, but the APP window is relatively small, if there is too much information, it will only reveal the previous part of the prompt information, and the flying friends should always pay attention." ”

Mr. Lin wrote in a post titled "DJI Royal 3 May Have Major Design Flaws": "Yesterday (March 24) when my Yu 3 drone took off, it suddenly drifted at a height of about 20 meters, flew obliquely to 50 meters away, and finally hung on a tree. DJI technicians contacted me, let me upload flight data, and then they analyzed the flight data and called me to say that when I took off, the signal was not good, there were less than 10 satellites, and the return point could not be located, so it automatically became an attitude mode, automatically looking for a good signal, so drifting occurred, at this time the obstacle avoidance function would automatically close, so it drifted to 50 meters away and hung on the tree..." However, for the explanation of the DJI staff, Mr. Lin did not approve, " If the Yu 3 drone does not automatically change into an attitude mode when the signal is not good, it will not float to a place 50 meters away; if the Yu 3 does not automatically turn off the obstacle avoidance when the signal is not good, it will not hang on the tree. ”

Apparently, the technical analysis of the DJI staff did not quell Mr. Lin's doubts. Under the online post, the account nicknamed "DJI Technician" replied to Mr. Lin, "If you have any questions about this analysis of the data, please inform the corresponding doubt points, and arrange for the staff to contact you." On April 6, the upstream reporter contacted Mr. Lin, who told reporters: "If the satellite is insufficient, the obstacle avoidance function will be automatically turned off, and the phone will be called many times, but it is not admitted that it is their problem." ”

Netizen hot discussion: This problem has appeared many times

The question of whether the design of DJI drones is flawed has also aroused heated discussion among netizens. Some netizens said that "this problem has appeared a lot, before taking off to search for stars to reach the set number of stars, it is fine, and I don't know what DJI thinks." Some netizens said that "without gps signal and can not enable visual positioning, or can be manually controlled, as soon as possible to land." The upstream news reporter saw that a netizen in the post also recounted the "bomber" process of a new Yu 3 that suddenly crashed into the trees on the side of the road.

Mr. Lin wrote in an online post: "Although the plane was slightly damaged, it cost a lot of money to remove it from a tree so high. I contacted DJI several times, and this was a major flaw in their design, so I should be reimbursed for the cost of rescue. ”

On April 6, Mr. Lin told upstream reporters: "At first they said that there was no funding to change the way, but then they disagreed. In the screenshot of the chat record sent by Mr. Lin to the upstream news reporter, for Mr. Lin to expose DJI's design flaws, DJI technical support responded: "For the sake of user experience, this side can apply for some peripheral gifts for you. Mr. Lin finally wrote in the online post: "They finally contacted me and said that as long as I delete Weibo, you can send me a gift, T-shirt, cloth bag, hat to choose one." I lost a lot, gave me a gift of dozens of dollars, it was really a loss for them to come up with it. ”

Customer service response: The "Fly with Caution" prompt window is smaller

In interviews with upstream journalists, Ms. Zhou, a citizen of Chongqing, had a similar experience. On the afternoon of April 6, she told the upstream news reporter: "Because some time ago, the DJI Royal 2 at home was bombed without knowing it, and recently I was watching the Royal 3." Ms. Zhou was also very curious about the "defects" that netizens Mr. Lin pointed out that could lead to the explosion.

On the afternoon of April 6, the upstream reporter called the DJI service hotline, and the customer service told the reporter: "When the number of satellites is insufficient, it will enter the attitude mode, in this case, we must pay attention to the aircraft, if it drifts, it is necessary to play the rod in time and operate manually." Customer service also admitted: "This requires the pilot's technology and timely attention, and if the operation is not good, it may lead to the explosion." For Mr. Lin's question that "there may be design defects", the customer service did not respond positively, saying that there is an explanation of the attitude mode in the manual, and in the upper left corner of the APP window, the flying friend will also be reminded that "it has automatically entered the attitude mode, please fly cautiously." "Because the prompt window is relatively small, so if it prompts too much information, it can only reveal the previous part of the information, but also need to click to view, at this time, the flying friend also needs to always pay attention to the relevant satellite information."

For the reporter's "cautious flight" text warning effect is weak, why not use the more intense effect of the "may bomb" warning, customer service said that it will record it and feedback to the relevant departments.
