Hey here are some updated versions, i put a piece of sheet metal underneath and ontop of the major structure, for aesthetics and it made it easier to mount all the parts. This can also act as parts of the floor.

by the way x marks the front.

i also rearranged some of the components to fit into the chasis between the motors. the highest point is the frame holding the motors, and the shocks which bolt into the frame which should be the part that tan is doing i think...
