When I open Plane Maker, in an attempt to modify the standard C172 panel, the panel is blank - no dials.

I then try to re-open the standard C172 but there is still no panel content and the program will often then freeze.

I recently did the latest X-Plane 11 update.

Any ideas?

I'd like to add a DME and HSI to the standard C172 panel.

Thanks,

David

You tried 2d or 3d panel...Anyway instruments are fully 3D, there no much you can do to edit the plane.
