I think DD looked into that, but couldn't find the option, Malo. And I do believe that he looked rather well. I remember that he posted a list of possible things we could change about the heli.
On another note, I think the point of the heli is to get in the face (back) of the good players so that the newbies get a chance, too.
I'd rather have the chopper has the current armor made of wet newspapers than a flying circus of death though.
