You can use FS Panel Studio for the panels in the VC, if you intend for it to be a 2D Gauge on a 3D backround. If you are trying to make a VC for the Posky-Project Airbus aircraft, I would suggest using Gmax to start on a model, then add more parts, such as switches, levers, and knobs before trying to add gauges. But the good thing about it being an Airbus is that it has a glass cockpit. This means that basically you can add gauges to the VC like you would a 2D panel in FS Panel Studio. And what sim are you using? I ask this as it can make all the difference, as I have no experience with FS2004, only FSX.
Zero Visibility? Not an issue when you fly with the RNZAF. Our 757s are specially modified for cargo and acrobatics.
