Can't calibrate the compass

[Stall]

Hello, a few months ago I dropped my P2V+ in the water and the gps stopped working so i replaced the gps module and it works fine now. But i still have some problems.

1) Everytime I try to calibrate the compass it fails. The horizontal calibration works fine but after the vertical calibration the LEDs start blinking red no matter how many times I tried. Should I replace the compass? If so, could anyone link to a tutorial and an online store?

2) Before every flight the display says "Remove Gimbal Cap" or ''Gimbal Motor Error''. I also feel like the image is not as smooth as it was before the crash in the water.

1) Yes you could start with replacing the compass on the leg. Good luck finding one.
2) That usually indicates your camera gimbal is not moving smoothly or it is locked up temporarily. The water may have damaged your gimbal motors or the pots that act as a control feedback of their position. Don't know how to fix that though.

Sorry I am not much help
