& to be honest, that should be it for data files. Try it out in-game at this point & check that it spawns. All that's left after that is to open 'newsmav.ytd' & export & edit the texture/s to that of a news helicopter/replace the texture/s with one/s premade from the site etc.
Alternatively, grab an add-on mod like this & use that instead. Just install it & then enter it's name in the '<Vehicle>' line of your choice in 'dispatch.meta'.
You may also have to add 'FLAG_LAW_ENFORCEMENT' to it's '<flags>' line in it's 'vehicles.meta' file to get it to spawn in-game as a dispatch vehicle & hang about the action etc although this isn't always necessary.
Where am I adding this to? The dispatch.meta or actual vehicle.meta or something?
