I've been trying to looking for decent drawings of the UD-4L "Cheyenne" Dropship's cockpit for the last 5 years, without much success. Last week, I have eventually found something that I use:
I also found a bunch of good movie stills, including photos of Dropship interior. This one of the 'cargo bay' has been very useful.
However, in the image below I spotted something that looked very wrong, guess what it is:
The HUD. It's too low and would make it totally impractical to use! I've watched this film many, many times and I missed this detail.
Anyway, I've made improvements to the cockpit and the next stage is to add the consoles and that useless HUD...
