GENERAL:
The standard Tri-wing chig attack fighter is apparently designed for air superiority/combat air patrol type missions, as it is not commonly seen to be invloved in bombing style attacks, except as escort. Observed in space, the fighter is extremely hard to detect visually, as it is painted a pure black, with a marking on one side, probably for identification purposes, or the "flag" of the chig homeworld.
WEAPONS: The chig fighter has only been observed to have a plasma firing weapon of some sort, which probably works via an electromagentic firing mechanism, based on observations of chig technology.
CONTROL: Little is known about this particular fighter's control methods. No gases have been observed from the craft that would indicate a rocket mechanism. A likely possiblility is that the craft uses electro-magnetic and intertial shifting of its mass to create an imbalance that "throws" it off of its straight-line path. This would seem to correlate with other observations on chig technology.
Like other chig craft, the tri-wing fighter is probably controlled via a bioconductive gel, which senses nervous impulses from the pilot's brain (assuming they have one) as if they were impulses to a particular muscle.
PROPULSION: The standard Tri-wing uses a complex electomagnetic "hand-off" style propulsion system in which an electromagnetic field, generated via the eletric conductivity of the plasma contained within the craft's engines, pushes on the craft and the surrounding space, causing a warp, which pulls or pushes the craft in the correct direction. This theory also suggests how the ship might be propelled, as the ship could cause differences in the strength of the field to pull the ship in a certain direction.
