Okay, I'm sure some of you have seen the M-505 I've been creating.

I am desperately in need of some help with it.  I'm a fairly decent 3D designer, but I'm just crap at panel design.  I want to do some glass cockpit stuff, mainly in the VC, but I have no idea how I'm supposed to do it, anymore.  I once made a full VC for an older project that I never released, but that was a full two years ago and I don't remember how I did it, anymore.

What I'm really looking for is some gauges for a twin turboprop, all glass.  Things like an FMC, and whatever else a small turboprop should have.  That's the other problem: I have no idea what gauges are actually NEEDED for such an aircraft.

As always, any help is appreciated.

For a little adendum:

How can I open up *.gau files (specifically "747-400.gau") so I can extract all the bits and see them laid out?  I want to modify some of them to suit my needs, and my gauge programming skills are horrible . . . right now . . .
