Adding armed vehicles without ammo when bought

[Hammer]

Is there a script that removes ammo from armed vehicles when they are bought from a trader? I'd like to add jets or many of the other helis, but they all spawn with ammo. Is there a way to get them to spawn without ammo? Also it may be a problem with the rearm script I have because players can then just pay to rearm their armed vehicles after. Is there a way to disable the rearming of the vehicles?  Thanks!

Still the best way imo http://opendayz.net/threads/release-remove-weapons-ammunition-thermal-from-vehicle-epoch-version.18044/
