A front view of my orginal mech drawing I did a few years back.
first drawing--> [link]
not to be mistaken as a fast moving type of mech, the obvious load and design of its wings is meant for it to hover like a helicopter, although it has after burners to dash in short burst of speed, its more of a mech strap to a huge jetpack. Such mechs won't be seen wondering too far out from their mother ship/carrier. they have high fuel consumption and have short air time before forcing to return back to ship to refill its fuel.
Other lighter variations of this mech are designed for much faster speed, and more of airel ship hijacking, boost off from mother ship, deploy onto enemy ship, detatch jetpack and hijack.
This version however is more for defence and direct assault. Other heavier variations may be seen carrying missile payloads and bombs
