Adding seeking rockets to pbr

[swordfish]

Hi
I downloaded a pbr that fires shells from the machine gun at the front. And i wanted to change the weapon to them rockets on helicopters that you put the box on the target and the rocket homes in on the target.
Heres the config, im not sure what i have to change to change the type of weapon it fires.
