Just a quick update, I added skirts and a turbo jet to the rear section. I figured one, but slightly larger, jet should be sufficient to propel it.
The complete OGRE. At the front I've added some styrene strips to fill the gap that was originally going to be an air inlet. But I felt it made the front too vulnerable, and OGREs need a solid front for smashin' up things anyhow, right? I will carve it to match the standard Mark III profile.
Though not 100% satisfied, This is the arrangement I am going with (though I may tweak the tower). I need to get this thing finished up and painted. Thanks for looking, Don.
