Is there somewhere to download a manual since all I have is digital copy? I don’t know how to change from cockpit to external etc and remove the outside gauges.
The outside gauges can be removed in the menu :
Options -> General -> Camera under Chase Camera : Instrument HUD off
The external cameras can be changed depended on your keyboard settings. Default is “END” to view the outside camera then move with the mouse. Or there are then fixed cameras.
The best way to view your plane is the drone mode. Not sure about the default keys. But its easy to use with an Xbox controller.
Is there a button to just push to make it go away and come back?
No i dont think so. YOu can either have it switched on or off.
I suggest you look at YouTube and the tutorials by Squirrel and others.
