Spark seems to be VERY sensitive to metal structures. I tried to take off about 20m from quite a big garage made out of metal and immediately got compass error. When I moved a bit further away from it everything was fine.

The same thing happened to me this evening. Was flying in the same place that I have done several times, just finished taking a panoramic photo directly above my head, and then suddenly flew off in 1 direction without any sticks being touched. Only had my spark for a few days!

Have no idea how far it could have gone or how to find it. Uploaded flight logs to DJI cloud, DJI Diana please help!!

I'm closely watching the Spark flyaways, as I just purchased one a couple days ago.  One thing I will say, is that people calibrating their compass before every flight are just asking for trouble.  I have a Phantom 3 that I bought in December of last year, and as of today, I have 85 flights on it.  You know how many times I have calibrated the compass?  Twice, and that was during the initial setup.

In my case I updated the firmware of the Spark and the RC and the app requested I calibrate. All my flights (14 that day) were fine.

Except the last one lol.

Hi there, i have had 3 fly aways leading to a crash. Everything has been fine then all off a sudden my spark flys off uncontrollably and crashes. I have calibrated the compass at the location and there are no metal objects anywhere. I dont know what to do. I feel at this stage that i have wasted my money

I think i know what is going on. I saw identical flyaway on FB.



First - reaching heigh limit
Second - Compas Error
Third - NFZ error
Fourht - ATTI mode forced

When a drone is hitting heigh limit something is crashing in f/w or app. Maybe not always, but it may be a trigger.
Another issue because of stupid NFZ idea.

In fact it was not fly away. Copter just switched to the ATTI and drifted by the wind.
Switching to ATTI may happen in due to compas interferences, lack of GPS or a bug. Its a daily situation, nothing extraordinary what could happen.

Bug is a theory, but also compas could be calibrated in magnetic field, and after flyig of magnetic field a compass may be just badly calibrated then may be turned off, what will result as switch to atti.

Another thing - stupid CE range limitation. Its really dangerous. People have no time to react after loosing GPS to take control over situation and return in atti.

DJI - you may try to replicate that issue. Everyone can make a test.
Set limit to safe altitude, for example 8 meters then hit it few times and try to trigger switching to atti.
