Some more time on the heavy hauler, esc / rx tray installed. Originally I wanted to make the cab hinge at front grill but am rethinking of using a completely removable cab. Magnets will hold cab onto frame and electronics (lights ) will be getting power from a simple contact tab. I haven't seen anyone do that before so I figure I'll give it a try. As lights on cab will be like 5-7 volts and not much draw. That eliminates me messing with a hinge setup and will give full access to battery. I still have to make the battery tray and figure how to fill the void, fake tanks? Flat enclosure between side skirts and frame.
