I received my Mavic Air a little over a week ago, and it has been a lovely drone to fly so far. I have no complaints about packaging, delivery, or initial setup - it has been a great experience from the beginning. Great work, DJI!
But then, today came the day that put all that to a halt. The drone crashed into a tree, lost a landing gear, took multiple instances of chassi damage, and probably has internal damage as well. Now, I have to go through the RMI process, and I have no idea what will happen.
I am very saddened and disappointed by this and have gone over the scenario multiple times. What I do know is that this was not a pilot error. The whole sequence was as follows:
1. Choose an open location in a park as takeoff and home spot.
2. Liftoff
3. Bring drone to about 4-5m height
4. Start moving around slowly (no sport mode, no auto features, etc)
5. Suddenly, drone starts giving warnings about "maximum flight altitude reached", despite being at 5m. Maximum height is 500, and I have without issue brought the drone up to 80+m just a few days back.
6. Drone starts moving backwards at a about 1m/s
7. Drone stops responding to stick controls - I push forward (the drone is facing me), nothing happens
8. Drone drifts towards a nearby tree
9. I am still trying to get it to move in opposite direction, it remains unresponsive. There is no indication that connection has been lost.
10. Drone reaches critical range of tree, and at this point the obstactle avoidance system should be kicking in (the sensors are facing the tree directly).
11. Sensors do not kick in, there is no obstacle warning. If they do work, they neither stop the drone or initiate obstacle avoidance - drone keeps drifting.
12. Drone drifts into treee foliage, carnage ensues, it falls to the ground. Rear-left arm takes the bulk of the blow, landing gear comes off.
I am wondering if anyone else has had something similar happen to them, and how you dealt with the service afterwards? To me, this is a clear case of multiple software failures in the drone itself - both the loss of control and the failure to avoid a clear obstacle. As such, I believe it should fall under warranty. Yes, I realise in retrospect that I could have tried to force land the drone, but everything unfolded very quickly, I paniced, and did not consider it at the time. I do hope DJI will it the same way.
Thank you very much for any and all feedback!
