Wow, that's really pretty. The bumper concept is simple and neat.

How are you dealing with the difficulties of adding a drop using the chain-in-tube system? Were you able to add a drop somehow or are the wheels different diameter? If so, how do you think that will impact the 6WD version, considering at all times the wheels touching the ground will be running at a different speed?

(or is that 3x1 tubing and I'm just missing it)
