Glue the rear of the fuselage together. Use a clamp to hold the

joint. Insert cross pieces 9 to help form the correct angle at the

rear. Check to be sure things are square and that the sides have a
symmetrical bend.

Glue formers F3, F5, and F6 to one fuselage side. Make sure
they are square to the side.

Glue the other fuselage side to formers F3, F5 and F6. Make
