A view from the front of the airplane shows the master brakes hooked up. Also, coming out of the front are the two battery cables and the fuel line.
This is the area between the seats where the handle is hooked up for controlling the elevator trim. The cable runs back under the floor boards to the tail.
This is the left side of the elevator which has the trim tab connected. After both pieces have been covered with fabric, the hinge will be riveted in place.
In this picture, a lightweight body filler has been applied to the wings. This will make a smooth transition from the aluminum spars to the wooden ribs. If it is not smooth enough, the fabric will show the ridges where they meet.
