The MonoBrunt is a transport carrier that utilizes sixteen rocket engines to provide lift for the cargo tank while the front wheel, which stays in constant contact with the ground, provides forward momentum.
Notice the missile launchers as ground support stands (whatever they'd be called). Once down, the missiles can be 'launched' to provide a cushy suspension while stopped and filling up.
I'm happy to have finally used the Bionicle package for something. This will not be the last time!
