Oh yeah also the rockets don't seem to hurt hunter-choppers, but work on gunships fine.

I could swear it was in the description, but apparently it isn't. Try out zapc_health on the server I think. There's quite a few cvars you can tweak (what was the command again to list them? `cvarlist zapc`?), including the health if I'm not mistaken.

As for not hurting them, the damage should be tweakable, too. But it's been a while, so I might be mistaken.

Thank you greatly. I'll check all that out.
