1. Body Front & Side
The first step is to begin assembling the main body. First, insert two hex nuts behind the tabs on the Body-Front piece.
Flip the piece over, and press down through the holes onto the nut so that it fits into the capture area.
Take a Body-Side piece, and orient it so that the top of the servo holder (the extruded rectangle on the back), is farthest away from the 'robobrrd.com' text on Body-Front. Place a #6-32 3/8" screw through the hole and through the nut. Screw it in until it is slightly tight. See the photo for an illustration of this.
Repeat the above steps for the other Body-Front and Body-Side pieces.
Next up will be attaching these two pieces together.
