If you want the MA-2A Zunis plus bombs loadout, in the F-4B data ini change the two sidewinder sections to this:
[sidewinderStation3]
SystemType=WEAPON_STATION
StationID=12
StationGroupID=6
StationType=EXTERNAL
AttachmentPosition=-1.77,2.59,-1.20
AttachmentAngles=0.0,-1.0,-90.0
LoadLimit=120
DiameterLimit=0.5
AllowedWeaponClass=IRM,RP
AttachmentType=USN
ModelNodeName=
PylonMass=
LaunchRailNodeName=
MinExtentPosition=
MaxExtentPosition=
[sidewinderStation4]
SystemType=WEAPON_STATION
StationID=13
StationGroupID=6
StationType=EXTERNAL
AttachmentPosition=1.77,2.59,-1.20
AttachmentAngles=0.0,-1.0,90.0
LoadLimit=120
DiameterLimit=0.5
AllowedWeaponClass=IRM,RP
AttachmentType=USN
ModelNodeName=
PylonMass=
LaunchRailNodeName=
MinExtentPosition=
MaxExtentPosition=
As you see from the screenshot they are horizontal not vertical. Does anybody have a better solution?
