I didn't have to change the gains, I noticed it was alot more stable in Atti Mode, like when it started to shake (when I booted it up while it was warm) I would switch to atti and magically it would quit shaking. I turned every damn sensor off, vps, obstacle, upward obstacle landing check, auto landing gear etc. I did a job recently in -30 Celcius, it worked like a champ, but I noticed it was unstable in GPS mode, so I used Atti as much as possible, I kind of had to anyway was flying under a glacier. Did you try using a different device? Such as an android tablet or phone? When I first got it to quit shaking I was using a Samsung S7 which I'm not 100% certain it was the fix, but maybe the android app was better at telling the bird to chill out.
Oh and I did a firmware rollback one by one to the lowest firmware they allow you to go back to. Starting with a factory reset (in DJI assistant, using a PC not a MAC). Then upgrading one by one to the latest. Following this I did the IMU, Gimbal, Sensor calibration with that rorschach board. Putting it outside (it was -36 at the time) I allowed it to cool, leveled the case out with a spirit level, and made it do its IMU check. Boom! it was solid again, even in GPS Mode. Super relieved. At -36 the landing screw froze, well I would say the grease froze and jammed the screw in flight mode. I had to hand catch it and it struggled to enter landing mode but it did. (afterward I took it home thawed it out and removed as much grease as I could from the screw using a toothbrush and Isopropyl alcohol, then I lubed it up with Remington Teflon Dry Gun lubrication spray) (in -36 when you go hunting, you have to strip the gun of all the oil residue on the action, usually with gasoline in order for it to work. very similar with this landing screw) |
