Artificial Horizons/Altitude Indicators are a common staples of both real life aircrafts and drones along with various simulators. It would be nice for the newly added VRChat drone to also reflect this common tool.

For context an Altitude indicator or Artificial horizon is the orange/blue ball showing the tilt of an aircraft or the degree indicators used in a game like Elite Dangerous when trying to land on a planet. As far as incorporating it into VRChat, this could be an overlay like the grid we already have or it can be rendered on the edge of the controller or FPV mode.

As far as the benefit of this addition, as a lot of players would be newer to flying FPV drones (even more so in VR), this would help keep track of the drone's current state. Currently the drone can be a little awkward to control given the camera tilt's adjustable state. I personally find it difficult to stay level with auto centering off since my only point of reference is if my drone is drifting in any direction.
