1) Using a modeling knife, remove the cov-
ering from over the precut hinge slot cut into 
the lower rear portion of the fuselage. is 
slot accepts the lower rudder hinge.
2) Slide the vertical stabilizer into the slot in 
the top of the fuselage. e rear edge of the 
stabilizer should be ush with the rear edge
of the fuselage and the lower rudder hinge 
should engage the precut hinge slot in the 
lower fuselage. e bottom edge of the stabi-
lizer should also be rmly pushed against the
top of the horizontal stabilizer.
3) While holding the vertical stabilizer rm-
ly in place, use a pen and draw a line on each 
side of the vertical stabilizer where it meets 
the top of the fuselage.
4) Remove the stabilizer. Using a modeling 
knife, remove the covering from below the 
lines you drew.
 When cutting through the covering to re-
move it, cut with only enough pressure to only 
cut through the covering itself. Cutting into 
the balsa structure may weaken it.
5) Slide the vertical stabilizer back in place. 
Using a triangle, check to ensure that the ver-
