Panic Attack Drum Removal

This mod is a basic model edit. It removes the drum from the Panic Attack.

It was a distraction to me and rather pointless in my opinion, so I removed it.

It should be completely compatible with skins, and the shell is loaded like it should've been originally (but Valve didn't check the model before adding it)

I'll add a version to SFM with a posable/bodygrouped drum.
