How do you remove the GAU8 from the A10?

[Sandy106 1]

I've been fighting with the editor for over an hour now and no combination of

this removeWeapon "GAU8";

this removeMagazinesTurret ["1350Rnd_30mmAP_A10",[0]];

this removemagazines "1350rnd_30mmAP_A10"

Will get rid of it. The AI pilot keeps using it instead of the bombs I want him to drop, what am I doing wrong here?

this removeMagazinesTurret ["1350Rnd_30mmAP_A10",[-1]];

{this removeMagazines _x} forEach (magazines this);

{this removeWeapon _x} forEach (weapons this);

works in script version
