For using Dinno Catanneo's F-14D default HUD for aiming & shooting the
CS Weapons, you may do the following :

1. From plane's "Panel" folder, copy & paste all folders & files except "PANEL.CFG" in "panel.csweapon" folder

2. For aligning 2D CS HUD aimpoint with default F-14D HUD aimpoint, use the following parameters in weapons .xml :

<Weapon>
           <Gun>M61 Vulcan</Gun>
           <Shell>Vulcan Bullet</Shell>
           <Unlimited>0</Unlimited>
           <Station name="Nose" params="0,9,0,0,-0.000,0,1200" />
           <Mode name="AUTO" shotrate="100" setshots="0" sequence="1" skipFrm="0" />
           <Mode name="X10" shotrate="100" setshots="100" sequence="1" skipFrm="0" />
           <DefaultMode>AUTO</DefaultMode>
       </Weapon>

Changing with "-0.000" at all weapons you use accordingly.

3. For the Gun Aimpoint to show up at F-14's HUD, press "SMS" in MFD screen & then the other button as in video (2nd button from left top - don't remember name...)

Another way of course, is just to turn off default F-14 HUD from the HUD switch at right panel (3nd switch down) & with shift + 3 to turn 2D CS HUD on with screen centered...
