One of my favorite builds from last year (and one of the few that I still have together). I built this one for the "Maschinen Krieger" Starfighter contest on flickr back in Oct 2011. Although not entirely visible, the engines can articulate at various angles.
Heavily inspired by the Lunadiver / Stingray.... and it does fit a minifig (see cockpit photo below).
Cool build - really diggin' the shark motif. I think it might look a bit more sleek with the radar-dish rig on the underbelly removed. Great work, though - You gotta love hover-gunships. - Huss Q.
