ASSEMBLE THE FUSELAGE
Install the Stab, Elevators,
Fin and Rudder
For the following steps you will need to have the bottom 
wing attached to the fuselage. If you have removed the wing, 
re-install it now.
❏
1. The center of the stab has been left uncovered for an
easier stab installation. Insert the stab into the opening in the 
fuselage. Position the stab so that it is equal in length on both 
sides of the fuselage and that the distance from the wing tip 
to the stabilizer tip is equal.
❏
2. Stand back a few feet and look at the stab in relation
to the wing. The stab should be parallel and in line with the
wing. If you fi nd that your stab is not aligned, adjust the 
stab by removing small amounts of the stab saddle with 
100 grit sandpaper.
❏
3. When you are satisfi ed everything is aligned properly,
wick CA into the stab and the stab opening. Work slowly, 
making sure that you apply adequate amounts of glue to 
secure the stab. Leave the stab undisturbed while the glue 
hardens. After the glue has dried you can remove the lower 
wing from the fuselage. Leave the handle in place to keep 
the cabanes secure while completing the remainder of 
the construction.
❏
4. Apply a drop of oil or work petroleum jelly to the center
of the hinge. This will prevent glue from getting into the hinge 
when you glue them in place.
