After working out the Air Brake, I continued work on the plane per plans except for the location of the retract mechanism and receiver location. Instead of putting both of these at the rear of the plane I relocated them further up which freed up room and took a little more weight off the rear. I installed the battery under the nose gear. The plans also used plastic pieces to cover the rear hatches and instead of that I used wood. I had some 1/2"X4" balsa on hand measured, and glued it in place then shaped it to the rest of the plane.
In the 4th picture I had to cover the holes with 1/16" balsa because I am going to fiberglass this plane.
The last picture is the Air Brake which needs to be a little more sanded to shape.
