I was having trouble controlling the Phantom 3A while doing video of a bike race over the weekend so later decided to calibrate the RC to see if that was the culprit. During the process I discovered that all the gains were set to zero.
I concluded that the lack of gain must have been the reason for lack of control and a resulting crash that damaged the camera which I replaced prior to the race coverage.
So, I reset all the gains to 100 (80 on yaw) but noticed that they would revert to zero after exiting and reentering that area of the settings.
Next step was deleting the DJI GO app and reloading. Then noticed that the gains were set to 100 except the yaw which was at 80 and I was able to exit and re-enter the menu without losing any settings.
I have the CSV file of the flight where the craft hit a tree , crashed and damaged the camera in spite of using full forward pitch to avoid. I can post the CSV file if anyone is interested in deciphering it. Also wondering if anyone has run into this issue of gains mysteriously setting themselves to zero.
Incidentally, I was running Litchi at the time of the crash.
