Hybrid Walker/Flyer Plasma "Flappy"
This is something I threw together to satisfy my bombing/walking needs: the hybrid bomber "Flappy".
As you can see, "Flappy"s main structure is a basic skeleton frame, making it light, agile-and easy to destroy. One good hit from a SMG on the body and your front/back parts are gone. As such, even I don't really rate "Flappy"s survivability rate. Yet, this bomber's power is quite good, able to fire all 7 plasmas at a 45 degree angle to easily strike enemies down. Got a pesky rail walker parked on a mountain? Sneak up to them and blast them in the face with the 4 walker legs you have. If all else fails, the cockpit does have engines attached to try and rocket you back to a medic.
As always, feel free to use, edit and comment on what "Flappy" can improve on (I know there is a lot to improve on, but what with my RP count and pFlops...)
