I started tweaking FS for my personal use about 14 years ago and I hope to give you some hints tuning 3rd party aircraft and the CSWeapon.xml ... <HudFov3d>17.00</HudFov3d> This variable only changes the size of the FOV, not the position. Looks like the position is linked to the aircrafts CG and can only be modified by changeing the eyepoint´s height (third variable, here 3.358) from the aircraft.cfg Example: [Views] eyepoint = -17.0, 0.0, 3.358 But that means that the pilots seat position might not be correct anymore... Now back to the weapons and HUD-aim Example: <CollimationData>0.0,14.01,3.358,0.307</CollimationData>                             A  ,B     ,C      ,D A - is actually equal to the second variable of your aircraft.cfg´s eyepoint B - same as above, first variable (if you change the - to + or viseversa the HUD is mirrowed ;-) ) C -same as above, third variable D - IS THE MOST IMPORTANT (and difficult to set up the right way). It changes the size of the HUD in VC. The HUD might be way to big at first installation or just as big as a few dots...I had to change this value very often. In some aircraft reducing this value increases the size, others react just the other way. Next example taken from the gun section: <Station name="Nose" params="0,9,0,0,-0.039,0,578" />                                                 A,B,C,D,E      ,F,G A - adjusts weapons position IN METERS! Left negative, Right positive (here 0=straight on the nose) B - same as above, Aft - negative, Forward - positive C - Negative - lower, Positive - higher D - E - Weapons angle (the variable you all are looking for!!!) Negative - below Horizont, Positive above Horizont - in this example -0.039 means 3.9° above horizont. For the IRIS F-14 it would be 0.033 to match the original HUD´s aimpoint F - Weapons angle Negative to the left, Positive to the right of the airvrafts longitudinal axis. Not sure but I think 0.1 equals 10° G - Ammount of Ammo (here 578 bullets) Whenever you want to adjust any part of the CSWeapon.xml, you must switch to another aircraft in FSX, since the xml is updated when leaving the aircraft. Otherwise, you don´t change anything at all. I understand that CS is not able to support any 3rd party aircraft on their page but I´d love to see some kind of CONFIG DATABASE for those aircraft in this forum or on the product page. Sorry for the bad language, but I´m writing this on an aircraft somewhere over europe with a lot of ATC...;-) Have a bandit day, Marc

Merida72,
Looks like the eye point is to low in the second picture, raise it to get calibration red circle higher, in game press shift+backspace(up), shift+enter(down) and watch that red circle move on the hud..Cntrl+spacebar resets. Change it in the aircraft.cfg, and update the .xml. And in the panel.cfg keep tuning it. Your almost their! The second pic. As for the first, I'm having the same problem with some aircraft, the gauge gets the top cut off of it. I don't really get it.
 
This is a very useful post, well was useful to me.
