The models are very modular, allowing for multiple weapon options. I took them a step further and mounted two sets of weapons: plasma and missile pods, in an under and over fashion (normally the weapon is only mounted on the bottom of the model).

|GZG UAV Grav Drone with Plasma Guns and Rocket Pods|
This conversion was unplanned. I buggered up this first model and had to put a rail gun on the top and the missiles on the bottom. I guess he could be an anti armor/aircraft model.
Overall I am happy with the way they turned out. They fit in perfectly with my Cyborg army and can be used as either heavily armored AI controlled Warbots or lightly armored Floating Weapon Platforms.
