Weapon group configuration on the F7C-M Super Hornet can be a pain to get it done right. It seems like the weapon selection is random, but there is a logic behind it.
I loaded the hornet with 2 panthers on wing, I replaced the canard turret with another Panther, I replaced the ball turret with a flashfire specialty mount.
Press F6
1st place is the canard Panther, 2nd place is the left wing Panther, 3rd place is the ball turret, 4th place is the right wing Panther. The ammo is sorted on the bottom
As you can see, fg1 has a Panther on 2nd and 4th place, fg2 has a Panther on 1st place a cannon on 3rd place.
Do you see the ammo places? fg1 on 1st and 2nd place a Panther, fg2 on 1st place a Panther and 2nd place the cannon.
If you go with your mouse over fg1, then next image will appear.
Don't look at the guns, look at the ammo. If you want to group all 3 Panthers in fg1, then you must select the 3rd weapon. The picture says cannon, the ammo says Panther.
Result is below, all 3 Panthers in fg1, 3rd Panther seems not to be selected, but ammo says it is selected ;)
If you move out off fg1 with the mouse, next image will be shown.
If you want to remove the Panther from fg2, then you must deselect the 1st place, but remember, when the Panther is gone, the cannon ammo will move to 1st place.
If you really messed up, you can fix this simple. Deselect all weapons from a firegroup. The ammo is matching the selected status, 1st, 2nd and 3rd place is a Panther.
Leave the firegroup with your mouse and reenter it again
As you can see, since no weapon is selected, weapon and ammo match again. Select all weapons you want to have in fg1 without get focus off fg1 (get mouse out off fg1). 1st, 2nd and 4th weapon.
With 3 Panthers and one cannon it is really simple, bullet ammo (100%) is Panther, cannon shells (120) is cannon. With mixed repeaters you can't tell on the ammo which kind off repeater you have.
I loaded the hornet with 2 panthers on wing, I mounted 2 Bulldogs on the canard turret, I mounted 2 Badgers on the ball turret.
1st and 2nd place is the canard turret, 3rd place is the left wing gun, 4th and 5th place is the ball turret, 6th place is the right wing gun. 2x repeater ammo in fg1, 4x repeater ammo in fg2.
If selected all weapons in fg1.
The ammo position will match with the weapon image.
If I remove the left Panther form fg1 (3rd position), leave fg1 and reenter fg1, then 1st and 2nd place will match, 3rd ammo is 4th weapon, 4th ammo is 5th weapon, 5th ammo is 6th weapon. To remove the right Panther I now must deselect the 5th ammo.
It is al little bit confusing, but once you get the hang of it, it becomes very logical ;)
[EDIT] Damn, the forum didn't follow me. Now I must repeat the whole process to get all images fixed :(
