1. Cut out (1-3).
2. Form (2) into tube around pencil and glue tab. Wait till dry.
3. Put glue on wings and place tube over dotted line on wings - note overlap front and rear.
4. Put glue on 3 and put over tube and body. Wait till dry.
5. Bend dihedral into wings - see end view.
Hold body tube and give gentle launch. If the swallowatil stalls and tucks, bend the wings up more (give them more dihedral). If it dives straightaway, bend them flatter (less dihedral).
