The aluminum is the same channel trim for 3/4" plywood that I have used on the Oshkosh and Kenworth truck chassis, I just had to trim it a little bit. thought it would make the tub chassis a lot stiffer... also the arching beam is printed but with a 3/4 thick plywood sandwiched in between the beam which is U-shaped, i had to scrape the upper middle part of the plywood to make way for the wires from the servo and the headlight and for the motor power lines as well... the plywood would give it stiffness and some weight.
