Lore:

These last times few scavenger that were recuperating primary materials in the Great Junkyard, awell nicknamed "The Haunted Scrapland" admit that they would have seen a big garden worm that has terribly mutated with a plane… concrete informations about it are not clear. It would leave horrible howls when diving and scare out every forms of life with its intimidating face that breathes as strong as a tornado. When on ground it sounds like an army of bulldozers making it shaking.

BUT, there is a logical explanations of this myth creature. According to experts of robotic and mechanic it would be a droneification of a plane using impratical mechanisms for articulation and a doubtful turbine system as propelling gear.
To prevent the user that it is landing well it has Jéricho trumpets equipped on both legs. The Plane-y drone would use articulated splints-sledge at the front to amortize frame when landing on ground as well very sensible but powerful tracked feet.
The terryfing aspect of this metallic monster is due to the plane decoration touch at first started by the installation of plane wings with steering plates replaced with standard sliding plates.

Feel free to leave comments, it wont bite you (gear bite are terrible) :)
