So, I've been having a few problems lately. I've tried farting around with different things to see if I can resolve them without luck. I'd appreciate any suggestions or advice.
Background
I've had my P3P for about 2 months. Many dozens of flights & 30+ hours logged. I did have a crash about a month ago and sent it in for DJI Care repair. It came back and now I've had the following problems. I'm frankly not sure if some of them are just noticeable now that I'm slightly more experienced or if they've only cropped up since the unit was returned from repair. I will say that I suspect they gave me a new-to-me unit as opposed to repairing my original. Not sure though.
Problem #1
The good old horizon tilt. I adjust it after takeoff but it will slowly reappear during the course of a 10 min flight or so. Frustrating. Pretty sure this wasn't there pre-DJI Care, but I honestly can't say.
Problem #2
On two occasions the gimbal has gone batshit crazy immediately after takeoff with actions awfully similar to the first 15 seconds of the video in this thread. I've reset all the settings via DJI Go after the first incident and it happened again. This is two occurrences out of dozens of takeoffs since returned from DJI Care. In both occasions I landed the aircraft, turned it & RC off and restarted. Everything fine for remainder of session.
Problem #3
The P-GPS stability when hovering is simply atrocious. Again, this is in dead calm conditions. The aircraft will "bounce around" five feet on any axis whilst hovering. I always have 14+ satellites and usually 16-17. This most definitely did not happen pre-DJI Care. Another P3 pilot saw it doing this and said it looked to him like the thing was going to flyaway, then changed it's mind. Repeatedly. I can always easily enough bring it home, but it's unnerving how unstable it is.
Problem #4
This certainly did not happen pre-DJI Care and I suspect is related to #3. The near-ground (ie. 2-3 feet) performance is horrific. Up/down, all around. I'm scared to land so I've resorted to hand catching which can be challenging because of #3. At first I though it was because the VPS was having trouble determining altitude since I was landing in wavering, but not tall, grass. I don't think this is the case. I've taken to landing on a flat grey rubber mat which, I assume, VPS can get a fix on. Landing is an adventure every time now. I have gimbal guard that I thought was interfering with VPS, so I took it off. No change.
Problem #5
Aircraft yaw will not hold steady. Calm conditions. Move forward. Yaw left slightly/softly (w/left stick) and release. Aircraft will slightly, but immediately yaw part way back to the right. The net effect is that if I want to change direction whilst flying forward I need to keep an ever so slight left yaw pressure on the left stick to hold that new direction. Aircraft will also "drift" when not even touching the left stick. Simply give it forward right stick and don't touch the left. After a few hundred yards of travel, the aircraft could be 10-20 yards, maybe more, off the center line of it's direction of travel. This one is the most annoying as it's making it impossible for me to get good video as I'm constantly dicking around with the yaw.
Any thoughts? Thanks!

- P3P -- 1.8.80
- RC -- 1.6.0
- DJI Go App - ios 2.8.3 although these problems existing on 2.8.2 as well.
- All my problems are in calm conditions (certainly less than 10MPH wind, most often near zero).
- I've done IMU, compass (only once after return from DJI Care), RC and gimbal calibrations a few times. No errors reported; no apparent effect on problems.
- 90% of my flying is with DJI Go although I'll use Litchi & Autopilot occasionally. Problems exist in all three. When in DJI Go, I am always in P-GPS mode.
- I'm always flying in the same 2-3 locations. Wide open for thousands of feet in any direction.
