The Orion 7-G52 Mining Cruiser was first produced in 2499. It served as an orbital base for smaller craft, which were the actual mining vehicles. The titanic mass accelerator cannon on the side of the ship always pointed away from the planet it was orbiting, so that it could easily fire capsules full of ore to the nearest planet or moon needing the cargo (the firing of the cannon was always timed perfectly so that no "accidents" would happen on the target planet's surface).
I just really wanted to use those ostrich heads. It went all downhill from there... :P
On another note, FBTB's Mech Madness contest is almost over, so that means voting is about to begin! I would appreciate your votes, but as always, be sure to look at the competition as well!
The conveyor/mining saw thing on the side caught my eye first: nice design! Then I saw the parts on the front and began to wonder what on earth they were. Great use of an unusual part. I think that the face on the minifig head is perhaps a bit too recognisable and distracting. I suppose that the blank head would be too blank though. Lastly, nice engines!
