Well, tonight I sat and did research to learn more about just what I was building!
First, I had no idea what these panels were that get cemented to the left side of the aircraft:
I thought they were armor plates or something.
Seems they are actually part of the XM35 gun system. The panels cover the added wiring for the operation of the gun, which consists of a 20mm canon mounted under the left stub wing and 900 rounds of ammunition carried in the pod fairings mounted over the skids.
The gun:
Seems that this machine is armed to the teeth! Along with the cannon, it also carried a 7.62 mini-gun in the chin turret with 4000 rounds of ammo, and a 40mm grenade launcher with 300 rounds. Not to mention the rocket pods carried at the end of the stub pylons!
The only thing I can't identify is the pod carried opposite of the 20mm on the inside station, starboard side:
I'm going to pop over to the helicopter forum and post a query there. I don't think it's a weapon.
