You need to be careful with the wind warnings and your battery level when that far out 39 % at 3400 feet out.

I get errors all the time with my spark and mine always drops into attitude mode every now and then. The spark doesn't have redundancy GPS or compass so it always happens just don't panic when it happens I absolutely love it when the spark goes into attitudes mode I don't know why dji don't give us a switch for it.

so it means when i got compass error spark went to attitude mode ? that is why it started to yaw so badly?

Yours didn't go into attitudes mode you just had yaw errors then it sorted itself out. It could of been anything that gave you the yaw problems, if it's flying ok now just keep an eye on it you should be ok.

Yeah do a imu use a spirit level to make sure the surface your doing the imu calibration is level and then what I do is do the compass calibration at the open field I fly at so I definitely know that there's isn't anything there to interfere with the compass calibration.
