I just got this message for first time. I turned on drone for 1st flight today and within 30 seconds saw "Processor chip critically overheated. The aircraft will turn off in 10 seconds"
yea fan was running and since it had been on less than a minute I dont think it was overheating, I think maybe maybe a glitch in the app. I did factory reset and tried again and at first it wouldnt unlock nfz and then "rth in nfz message would pop up and then go away. Normally that message I have to clear by touching it and the app has froze a few times at startup recently.
Anyway it seems to fly fine so I will keep a close watch on it and hope for the best
