The only way to solve the Jello problem is by eliminate the gimbal calibration. Either by changing the gimbal rubber absorbers or by replacing the gimbal completely. The first you can do it yourself, the second if under warranty can be done by DJI.
Thank you for giving these valuable information. Something which makes me wondering is the "value" of this controller modification, because I have flown to a range of 8.250km (27000 ft) with stock antenna (no modifications at all) and the remaining battery at landing was 15%.
Let me give you a different answer. YES!
The reason is that the rubber vibration absorbers which are inside the shell, are under pressure when you use the gimbal lock only. On the other hand this pressure is reduced when you put back that thing. In this way you prolong the life of the vibration...
If the slide at manual focus is at infinite then you noticed gimbal movements and if you set the slide at the middle (lets say) then the gimbal remains steady?
Yes, I had the same thoughts about focusing vs camera movement. Yes, also I noticed movement of the camera without taking photos or anything else (but I will test this again to confirm). Please explain the "... Next I switched to manual focus and as I used the on screen focus slide, I observed...
Yes, I noticed sometimes that the gimbal is moving a little even without touching the RC. I will check that again and I will let you know, however, I do not have access to my P4P until next Sunday.
I checked the 4 photos you took (without video) and I see that the camera does not stay exactly...
I would appreciate it very much if you can take some sequential photos (let's say every 2s) while drone is sitting still on a table, and upload them here, in order to compare it with the behavior of my drone. Would it be that possible for you?
