ok I'm getting frustrated in regards to the VC 3d hud!!
I've tried this on the
Iris Fulcrum K,
the AlphaSim SU33 and the
vitrivia / alpha F4 package 3
Swapped the standard hud in the panel.csweapons/panel.cfg file for the csweapons hud using pos:x and Pos:y from the standard hud and dimensions of 550 x 550  (I assume I should keep it at 550x550)
upper left corner of hud starts where it should but VChud size is wrong  it's is huge!!!

Sooo go to csweapons.xml in the mentioned aircraft folder and changed the vchud FOV from 17 to 8  This gives multiple results;
no change at all, (most often)
mirrored hud same size (large),
mirrored hud low and to the right (like it starts at 550 in and 550 down
right size right orientation and right position but the font is so mushy and pixelated it can't be read

I have acquired the x and z co ordinates from the aircraft.cfg and got the y co ordinate from moving the eye point.

Sooo reset the csweapons.xml to stock
went back to panel.csweapons  panel cfg changed the hud size to match the original hud dimensions  got a good size well placed but unreadable hud

what is the magic combination?
how do I un-mirror a hud?
How do I get a clean hud?
where do I find smart pills?

Is hud radius; the 4th entry realative to the aircraft model size or the computer generated image?  4" (.307 feet) seems a bit small for a hud in relation to the size of the aircraft

I have found that FSX needs to be closed when editing the csweapons.xml on an individual aircraft

Collimate need to be set to 1 (turned on) to see the changes


(edit)after a few hours and setting x y and z correctly!!! I still have a huge hud or a mirrored hud
