I have a Mavic Air
and have an issue since yesterday.
the main controller says "Main controller data error ,
and when I click on the "overall status" I have many errors poppin up:
Gimbal cannot receive main controller data
Accelerometer failed
Gyroscope error

this Mavic air is brand new, just a month old, flew it just a couple of times and I never crashed.

would be curious to hear whether people have had same issue and if they were able to solve it
Thanks

Try to refresh the craft and controller firmware, then do a factory reset on the craft, then refresh it again i.e. twice in total.
If you're still getting failure errors (specifically), I suggest you return it - failure errors out of the box are unusual.

My unit has the same error last year and it was motherboard defect. I sent back to DJI for warranty claim and now my unit flying flawlessly. You need to raise a case and DJI Support will check your case. Hope you get back to the air soon.
