Hello again ICE,
XFLIGHT has no plans for the panels, it has printouts for the panels wich are 1:1 or very near to, so you can get a good aproximation. Like I said I haven't started that build no, and if I actually get to build something it will be more generic and less F-16. You don't have to take those plans to the letter, and you can easely add height, even though you dint mind the low height aproach, you ,may prefer diferently, I think at the thime I was designing it that way to build on top of a bunk bed (not very high ceiling).
On those plans if you check you'll find that the seat Position and general ergonomics do aproach that of the F-16 closely.
As for the measurements I got them from various sources, a lot from Viperpits.org, sure there are people there selling plans that are extremly acurate, but you can also find a lot of Measurement information on some of the build treads themselfs.
It's a lot of work to browse through them, as most of the treads easily span several dozen pages. But it's there.
I though the sketchup file could be usefull to you if you want an aproximation of the F-16 cockpit ergonomics that are easy to build, but if you want go near to the actual thing you need to do further research. Take the plans on xflight as an example, they are way off the actual thing, but the guy built in the past a perfectly functional and aproximate cockpit (that I would love to have) on those plans. If it's functionality and ergonomics you are after, those general dimentions should not fail you.
