This type of mecha is a hybrid of the Aerofighter and Battroid mecha, resembling birds or winged humanoids. They're capable of both flight and ground based movement.
-3 MV, +0 TR. The bastard child of a Battroid and a Hoverfighter. Doesn't need to move forward to fly, and has a low maximum walking speed. It does nothing well, but also does nothing badly. GerWalkers get a 25% bonus to Flying Thrust (calculated toward speed).
