I have a problem with my APM2 where it thinks it's -5 degrees when it's level. I've measured absolutely everything to make sure it's not my floors, my quad, my construction, etc. Just to show how much it is, I tried to take this picture to show how bad it is. It's not easy to see it due to picture quality, but in the mission planner, it's almost level while you can see the bubble being all the way to the left.
Is there anything wrong with my sensors or is there a way I can reset them? I'm running the latest firmware and newest mission planner. I don't dare to try and fly it the way it is now.
