Command to delete player copters?

Is there a command that will allow "Admins" to delete a player's copter?  And perhaps a command that will delete "ALL" player copters?

I can see a problem with ppl just spawning in Copter after Copter after Copter.. Since there isn't any cost and they don't appear to take damage, They could become a real strain on my server..
Maybe an option to have the copters cost something?  And have that configureable in the config files?

Thanks
