Keep drone upside down

[KwanYong Cho (kwanyongcho7)]

I am using Px4 with HITL, and I want to keep my drone upside down when it collided.

Now, Airsim automatically fixes upside down, which my drone thinks it is still upside down..

Is there any way I can remove automatic fix for upside-down?

This can be achieved by disabling ground lock in the FastPhysicsEngine setting:

{
  "SeeDocsAt": "https://github.com/Microsoft/AirSim/blob/master/docs/settings.md",
  "SettingsVersion": 1.2,
  "PhysicsEngineName": "FastPhysicsEngine",
  "FastPhysicsEngine": {
      "EnableGroundLock": false
  }
}
