This is a really funny voice pack, I'm amazed at all the voice lines you used hahaha.

I actually do some tf2 audio splices from time to time and I happened to have one here that you may be able to use. In the voice pack, the heavy references gunships as "Tank birds" and helicopters as "birds".

I have an audio here were I did manage to make him say "Helicopter", so if you want to use it, feel free to do so.

Love the mod and I hope you'll do the same for other classes as well, I literally cry with laughs when on a squad with multiple heavies hahaha.
