1 Setting a whitelist
To set a whitelist, set the ace_pylons_magazineWhitelist variable with an array containing possible magazines.
For example, place an AH-9 Pawnee, with the following in init line:
this setVariable ["ace_pylons_magazineWhitelist", ["PylonRack_7Rnd_Rocket_04_HE_F","PylonRack_7Rnd_Rocket_04_AP_F"]];.
Blacklists are set in the same way. Set the ace_pylons_magazineBlacklist variable with an array containing banned magazines.
this setVariable ["ace_pylons_magazineBlacklist", ["PylonRack_7Rnd_Rocket_04_HE_F","PylonRack_7Rnd_Rocket_04_AP_F"]];.
This would set the only available loadouts to be Hydra 70s. This will not change what is loaded by default, or affect whether it can rearm.
