Hello folks.
Here's the good news: I got some great shots.
The bad news: My P4P v2 got pretty beaten up.
This challenge is for those with some experience diagnosing and repairing these drones and, specifically, the gimbals.
I've got it back to full flight capabilities with the exception of a rear sensor that needs to shift slightly to sit properly in its opening.
The challenge now is to diagnose the gimbal problem(s) based on the following symptoms:
I've done an ICU calibration, gimbal and compass calibration. I'm not getting any errors (other than the backward vision sensor calibration failure).
I understand that the yaw motor is usually the first to be impacted in a crash but it seems OK. But it is not being activated during calibration.
The roll motor seems to function under normal flight conditions even though it's not being activated during calibration, but it would seem it's taken some damage.
The pitch motor seems to be working but what is the deal with the slightly downward angle after pushing it upward (but not downward)? Electronic speed controller? Something else?
None of these parts are easy to find--if I don't want to take my chances waiting a month or two for a part that may or may not actually work. So would you be replacing the roll motor, pitch motor, yaw arm, ESC? None of the above? All of the above?
Maybe it's all working fine but my drone is mad at me for letting a tree beat it up, in which case I'll talk to it nicely until it comes around. I'm guessing that won't prove successful, so any advice would be greatly appreciated.

The challenge now is to diagnose the gimbal problem(s) based on the following symptoms:
- The gimbal yaw arm is bent (see the images). That's an easy one (although getting a replacement that's been manufactured with the slightest quality control may not be so easy). BUT, weirdly enough, the camera is tracking the horizon and the video is smooth (see the test flight video).
- The gimbal autocalibration thinks it's calibrating successfully, however it only pitches the camera up and down then sits there for the rest of the calibration without moving the roll and yaw motors.
- When fired up, the gimbal occasionally makes an unhappy sound, pitches the camera up and down, then settles into a proper leveled position (see--and listen to--the video of startup).
- With the power on, the camera keeps itself in the proper position, snapping back to center after being moved in all three directions (startup video)
- BUT, two other issues are occurring:
- You will note in the video that when the camera is rolled to the left far enough, I get an ugly grinding noise. In flight, the drone would rarely roll that much except perhaps during a significant course correction at high speeds in sport mode. But, still, there's a problem there.
- Also, note that when the camera is pitched downward, it snaps back to level, but when it is pitched upward it snaps into a slight downward tilt and stays there until the power is cycled off then on again.
