I think I have been fortunate in that I've not experienced the flight stability issues after the firmware upgrade but I only did two test flights, taking the battery down to around 60% on each flight. I upgraded the P4 with via DJI Go on an iPad Mini 4, got the 99% issue and realised I had to upgrade the RC unit as well.
Being suspicious that each battery needed updated and that DJI GO wasn't offering to update my two additional batteries, I then connected the P4 to DJI Assistant and forced each battery to update. Whether this did something additional to the P4 firmware that using GO alone hadn't is unknown.
After that, I calibrated the IMU on the kitchen top which, by good fortune, is as level and solid as I could ever hope for.
I wonder why some P4s are affected by the stability issue and others are not. Could it be manufacturing tolerances between IMUs that are not readily accounted for by the new IMU calibration process? I've always been irked by the P4s internal fan coming on during an IMU calibration as I'm sure that will introduce some vibration and skew the measurements. Purely conjecture on my behalf but it sure would be interesting to see a comparison between raw IMU calibration figures between affected and apparently unaffected P4s, not that we knowingly have access to those.
I have yet to try recording to see if the gimbal/camera reboots in flight... |
