I put all the vehicles into a members group for entities and set the ruleset to "players can hurt vehicles" and all the vehicles take damage except the minicopter. Minicopter wont even take fall damage. I don't have the flag for it to be immune so I don't know what the heck is going on. I used "minicopter" as the member name along with "minicopter.entity.prefab" when that didn't work and still no luck.
