title_body: Why does the video cut out on HX-100 drone? I have a BetaFPV HX-100 drone which I recently got. When I tried to fly it FPV the video feed would cut out and leave a grey screen. The OSD still showed up in the goggles so I'm not sure if there is a problem with the camera or video transmitter. 
  
  The VTX was hot to the touch and the camera was warm. It was not the output power setting of the VTX because it cuts out even at a close distance to my goggles. I would appreciate any ideas on how to fix this issue.
  
  This happens when flying normally or even hovering and the grey screen is a solid grey, not static. I have not had any big crashes with it.
upvoted_answer: This sounds like a loose video wire from your camera to your flight controller.  Since you still see OSD, but a gray screen, it indicates that the connection from the flight controller to the VTX is good (that's why you are seeing OSD), but the gray indicates that something is wrong on the camera end.
  
  A warm camera is a little alarming.  A warm VTX is normal.
  
  I would check all of your connections to your camera.  If they all seem fine, then the problem could be the camera (the warm camera seems culprit to me).
