I looked through quite a few pages and couldn't find anything on this.
Why not have a list of all the things that could be damaged on your own plane and choose to damage one, or a
few of them, so you can practice flying without a wing or something? I'm pretty sure it doesn't exist already,
and having it on the Training mode or offline practice mode would really help you when you're in the actual
arenas, in a situation that you can't really practice for offline, again and again, until you have gotten in right.
It could also make some interesting fights, someone flying around with no wing taking out a whole lot of people
before they can no longer hold on.
