Just finished adding quite a bit of detail to the a-4c attitude indicator.  A
few things to bring up:

1) The flags.  There are four of them in the photos I've seen but so far I
haven't found any information on which is which.  One has the word "Off" on
it, and I assume that it means the entire assembly is unpowered.

2) The calibration of the turn-rate indicator is just a wild guess.  If anyone
knows how it should respond please let me know.

3) The GS indicator is not enabled yet.  Also note that there is an aircraft
sillohette behind the cross hairs.  I'm not sure how to animate it (maybe it
stays with the gs arrow)?

4) The size of this thing is somewhat difficult to judge from the photos,  but
comparing it to other items on the panel, my guess is the ball is about 4" in
diameter and the outer bezel is about 5 or 6".   It looks bigger in the one
A4-C cockpit photo that I have, but I believe that the A4-C panel is narrower
than later models.  AFAIK the A4-C is the first in the A4 series to have this
"all attitude" instrument.

5) The X15 (see http://www.sierrafoot.org/x-15/panel_large.jpg ) used what
appears to be the exact same instrument (with the exception of the glide slope
scale in this diagram).  So, I'm bringing up the issue of where to locate 3D
instruments in our tree.  Currently this one is in the Aircraft/A4/Models
directory,  and I'm not sure where we ultimately want these to end up.  I'd
prefer not to mix them up with the 2D models.

Best,

Jim
