Unfortunately, because i'm using the demo p3d, there is no proxy for handguns, there is probably a way of implementing it with O2, i'll ask on the official forums.
So for the time being I will make Pilot with no helmet, no pack, and an mp5
@erfworm, pilots don't, they have a gunholster on their left, at the bottom of the ribcage:
( g) - arms
I I - body
^ - legs
g = gunholster
will post a better pic when i get home
