I've posted this a number of times, but here goes again:
Was the battery in the drone updated to the same firmware revision as the drone had?
I updated my mini, the RC, and my phone from 1.0.3 to 1.0.4 a few nights ago. When I did the update to the drone, that automatically updated the battery that was in the drone at that time. But that left my other two batteries with their older firmware (could have even been from before 1.0.3, since my drone updated to 1.0.3 when I first fired it up, and again, I did not update its batteries because I saw no indication that this was required.
Anyhow, when I flew with the two NON-Updated batteries, the drone did a very strange thing.
It flew normally up until the battery level got down to around 50%. Then it suddenly descended to only 1 foot above the floor. (I was flying indoors, thankfully). When this happened, no amount of up-stick with the left stick could get the drone to rise. It hovered at 1 foot above the floor for the remainder of these flights. I think ground effect is what allowed it to actually sort of hover, but had I been outside, this loss of power would have caused a crash or loss of the drone.
I later found out that you need to update the battery firmware any time you update the drone firmware. So I have updated the other two batteries, and now the drone flies OK with those batteries, too.
Is it possible that you were flying with a battery that had not been updated to the same firmware revision as your drone had when you had this crash? If what happened with my drone happened to yours, the effect would have been exactly what you saw. I'm just lucky that I was unable to fly outdoors here due to the weather. Otherwise, I probably would have lost my Mini, too.
I can probably find the flight logs for my two "non-updated battery" flights and upload them, but they have no GPS data because I was just flying in my office area.
Anyhow, I think these drones should always auto-check to make sure the battery firmware matches the drone firmware before they allow you to fly. This seems like a serious problem. |
