Just finished successfully updating everything - aircraft, rc, batteries and the new IOS app.
I got the MC Error today for the first time flying over water. I freaked out, immediately thinking it was a "Mission Control Error" and neither Major Tom or Houston were anywhere to be found
After reading up top, I am happy to learn it is only a memory card error. I am still using the stock MC. If I am caching my videos with the new director, would this be the reason I received the error?
My memory card was formatted before the flight.
If I want to cash the video I take, am I going to need a higher capacity MC?

Main Controller error. Is that MC Error or MC Data Error?
I suspect it's related to the SD card in Main Controller which is used to save flight logs, when the card is full there will be a "MC Data Error" hint.
It's ok, don't worry. Reboot your bird then SD card will empty itself and re-save the data.

Ty for that info Autumn I had the same issue this evening...MC and it instructed me to reboot the air craft ..I did so and all was good.
I about had a stroke....just loaded the new FW too...had a few glitches but I reloaded it and all is good.


Question: will this happen often???

Same happened to me over water, I almost had kittens ( a saying here in Scotland) it was by my side and on the ground In less than a minute.  Didn't fly it again until I found out what it was.  DJI why the red warning and not yellow or orange as it does not effect flight safety?

LMFAO @ Major Tom!

Did you take your protein pill and put your helmet on?
