Damn. Oh well, that's life....hmm...
What if two addons were to be linked together as one? What I mean is, there is one half of the helicopter which has the pilot and a gunner (this is one addon) and can hold half the amount of troops a whole blackhawk can, and the other half has one gunner position and the gun changes with addweapons depending on what gun the person who fills the space is holding?
The two halves are put together permanently as if one were carrying the other, and they are created as a group rather than as a unit.
I think it could work. If a blackhawk addon is able to carry a humvee, this should be able to work, right?
