Thank you for the answer! The developer said that it is ok to modify his program but he did not provide any further help.
Now I read the document about setting up GPS and about 2d and 3d views, but I am still confused. When I place gauges in there, they don't even appear. I don't quite understand this because I have watched videos on how other people do it. Still, when I open the helicopter in X-Plane, I follow the instructions but the gauges do not show in the sim. Is there another resource (text or video) that I can be looking at to learn how to properly design this cockpit? Especially the 3d cockpit, because that's where I fly from. When you open it, it is basically a black background with the gauges / displays on the black background, but it seems that there is no rhyme or reason to the layout. i.e. The 3d layout in plane maker does not look like the in-game 3d cockpit layout.
Help .....please.....and thanks!
