Assemble the wooden fuselage parts first. Then add the aluminum tubing. Make sure the tubing is parallel to the fuselage and that it is not recessed behind the front of the balsa structure. Notice that there is one piece of tubing at the bottom and two at the top.

Make the rear wire piece from a long piece of wire. You will cut off the excess length. First bend the lower part. This is called the tail hook and holds one end of the rubber band. Use a pin to make a hole through the fuselage and then insert the remaining wire through the hole. Bend the wire 90 degrees so it lays back along the upper surface of the wood.

Finish by making an upward bend for the rear spur, which will hold the tail in place, and cut off the excess. Make sure the rear spur is straight up and down when viewed from behind; carefully fix it if necessary by holding the tail hook and twisting the rear spur. Bind with thread where indicated.
