@Bunny Clark Hi Bunny, thanks a lot for your great profile. I have set it up all the viewports are working fine but seems like the connection on Armament, NVS mode and Video panels to DCS are broken, however the external/internal light panel is functioning....you might have a hint for me how to fix it? thank you.
btw the DCS.AH-64D.hif.json file is in place according to your instruction...
