Something is missing. Make sure that the file/folder structure of the LC130 is correct

folders in CS_EX2_LC130:

model.13
model.13g
panel
panel.g
sound
texture.us_pol

files in CS_EX2_LC130:

aircraft(.cfg)
C130(.air)

Is the entry in the aircraft.cfg the same as this:

[fltsim.0]
title=CS LC130Extra2 0
sim=C130
model=13
panel=
sound=
texture=us_pol
kb_checklists=
kb_reference=
atc_id=130
atc_airline=
atc_flight_number=
ui_manufacturer=Lockheed
ui_type="LC-130"
ui_variation="US NAVY (polar)"
ui_typerole="Multi-Engine TurboProp"
ui_createdby="Captain Sim"
description="'C-130 X-perience' Pro Pack v.1.3\n(c) 2008 Captain Sim www.captainsim.com"
flg="USA"

Make sure that sim=C130 is there and correct. If it isn't then you won't see the model either.
