I sent the drone in for repair, providing DJI with photos of the battery issue, the drifting and spinning of the unit while not even touching the controller, the massive real time video feed lag from close proximity between remote and aircraft, proof of purchase and several other identical forum complaints.
Immediately upon receiving the drone back, all problems were still present. Including the issued batter NOT able to clip into the aircraft battery housing.
The red non clasped battery indicator very present and aircraft will not fly with that battery due to inability to seat.
Message sent to DJI:
An update since the last messages sent to DJI. I had taken the drone to effectively test once again away from any cities or areas of significant electrical interference. Even in the remote locations the drone failed to reach any acceptable distance without significant real time video transmission feed loss, nor would the drone hold position. On several occasions, the drone drifted or spun in place without any controller manipulation whatsoever. During flight, the additional movements outside of my control made it difficult to control the unit effectively.
During final location takeoff for the day, I once again went through aircraft setup as I always do. IMU and Compass calibration, ensure firmware is up to date, and location is valid for safe and non restricted flight. Initially, the remote, once again, continued to beep but for no apparent reasoning. The battery was exchanged for a fully charged component, the remote was at 4 battery bars and the samsung galaxy s9 plus, connected, was at near full charge. I reset the controller and aircraft several times, noticing that the system had also been attempting to bypass the connection phase, in pairing between remote and aircraft. As soon as the application was rebooted, the view would jump straight into the drone camera view, making me manually back out for calibrations.
Once I finally got the controller to quit beeping and the drone paired and calibrated to my satisfaction, I placed the unit on concrete roughly 6 feet away from myself, my wife and her car. I initiated liftoff and let the drone hover in place while I set the controller down and my wife and I turned around to her can and began organizing the equipment.
The sound of the drone began to increase so I turned around and saw the unit drifting slowly in a backwards arc towards us. I grabbed the controller and attempted to push the forward thrust remote stick only. The drone failed to respond, so I pushed the elevation stick and the drone lifted slightly but did not look as though it would effectively clear her rear cargo hatch without contact.
By this point my wife turned around face to face at eye level with the drone backing into her at head level. Without being able to safely adjust elevation, and the inability to move the drone forward due to malfunction I instinctively raised my hand to shield her face from being struck, and attempted to stop the drone by the back plate at the pairing button. The drone somewhat bounced off of my fingers and bumped forward with a slight change in pitch to where the propeller caught my finger, and sliced two of my fingers open and broke one nail.
I am, however grateful, that the propellers stopped spinning after hacking into my fingers, because my wife instinctively caught the drone, and luckily didn't suffer the same painful infliction as myself.
What doesn't make sense, still, is the pitiful video transmission at a small fraction of the marketed specification distance.
The reasoning for the drone to continue spinning while the controller is not being manipulated. Not to mention, this was supposedly replaced and tested by DJI's repair facility. Once again, this is another supposed repair that continues to malfunction.
the drone also did NOT issue a backup proximity warning, as it was set to do. The aircraft did NOT beep, nor did it stop, as it was closing the distance to my wife's face. The size of the car alone should have offered enough surface area for the drone to register, but it did not. The drone was NOT on sport mode. Instead of potential costly damage to the new vehicle, the aircraft damaged my hand which still has not healed.
DJI's representatives still fail to offer any type of assurance they will or even can solve the aircraft's problems. DJI also ignores their own promises to provide analysis and bench testing reports to prove repairs were effective and show signs of drone even being able to achieve the DJI marketed specifications published, as my screenshots suggest, during the time of purchase back in the summer of 2018.
Reduction in posted capabilities since that time alone, suggest DJI failed to support the numbers originally published for the DJI Mavic AIR.
However, DJI can't even get the drone to adequately represent the numbers currently published for these particular units. |
