7. Once alignment is verified glue top of fuselage to top of wing assembly. Use a thin

bead of Welders glue on the lower mating surface of the upper fuselage spreading glue

evenly with your finger. Do not put glue in the area forward of the aileron servo cutout

or forward where the motor mount will go.

8. Using a straight edge insure the top fuselage is straight along the length of the wing and

tail section. A carpenter's square can also be used to insure the upper fuselage is square

to the wing and tail section.

9. Let the upper fuselage and wing assembly dry for a few minutes. It is a good idea to

press the upper fuselage assembly firmly into the wing and tail sections making sure

the upper fuselage is not lifting or separating from the wing assembly as it dries.

10. Next test fit the lower fuselage into the bottom side of wing and tail assembly. Make

sure the lower fuselage and rudder fit flush against each other this joint will form the

lower hinge.

11. Place fuselage upside down on edge of table, and place a weight on top of the wing to

keep it stationary on table.

12. Again making sure the lower fuselage to rudder hinge area is flush against each other,

glue the lower fuselage to the wing and tail assembly. Do not glue forward of the

aileron servo or the motor mount area. Let this assembly dry for a few minutes.

13. Place a small bead of Welders glue on the lower rudder hinge line and fuselage area.

Run a popsicle stick or scrap piece of balsa along the hinge line to spread glue evenly

to form the lower section of the hinge. Using a push pin in the top of the rudder and

down into the vertical stabilizer will aid in holding the rudder in place
