First time flying the Mp today after having the ribbon cable replaced, all seemed good then this happened


Not just once but 3 times whilst flying, i landed and restarted everything and all seemed fine, as you can see (thank god I screen record all my flights) the compass is showing as green in the app yet it states compass error
Im on 01.04.0300 firmware all original.

I did a compass calibration and it didnt happen again, but im a bit worried as im off to Portugal on Monday and will be taking Bugsy with me.

Fly it as much as you can now, before your trip, and if it does it again or does it every flight, pay another visit to the repair shop. A compass error is my least favorite message because it could lead to flyaways...

I know that further investigation of the logs is coming, but I am intrigued by a device called CFixer (CFixer is the Compass Error Fixer) and am wondering if this could fix the compass issue. I have read some posts where it has.

It depends on the exact nature of the compass issue. A demagnetizer may be useful if the problem is caused by magnetization of a ferromagnetic component or components (such as screws) on the aircraft that cannot be calibrated out.

Maybe when the repair shop did the work, some of the screws became magnetized.

I'm confused - that log is riddled with yaw and compass errors.
Your confused mate ? im seeing green on all the sensors, where do you see errors ?

Any how ive just test flown it and it seems fine now

The notifications tab is the first place to look. That is generally the only place that will note the errors. Without having seen the actual log files my guess from the notifications would be that the problem was caused by powering up the aircraft at a location with a distorted magnetic field rather than a compass calibration issue.

Wow I don't know how that mavic didn't fly off from you

You had about 300 yaw errors that place you are flying or taking off from has massive amount of magnetic interference

Ive flown the same place for 3 years now, most weekends our group meet up and fly there, this was the first time ive had any issues, im wondering if the sun and the weather played a part, or was it all that was needed was a compass cal after it had had the cover removed for gimbal cable replacement, guess ill never know as its flying fine now
