Install The Dowel Stringers - GREAT PLANES ElectriCub Instruction Manual

5. Set the fin in place, using the lines as a guide. Sight
down the fin, checking that it is in line with the centerline of
the fuselage. It is very important that the fin be aligned with
the centerline of the fuse. If it is not, the plane will be difficult
to trim. Use a square to check that the fin is perpendicular
to the stab. Use 30-minute epoxy to glue the fin to the stab
and aft deck base.
6. You previously cut the hinge slots in the rudder and fin
TE. Mark the location of the bottom rudder hinge on the
fuselage tail post.
7 Cut the hinge slot in the fuse tail post and trial fit the
bottom rudder hinge in place.

Install the Dowel Stringers

1. Position one of the 1/8" diameter dowels in the center
notches of F-3A, F-4A, F-5A and F-6A. Sand the aft end of
the dowel at an angle to match the angle of the fin LE. Glue
the dowel in place. Then, cut off the forward end of the
dowel flush with the front of F-3A.
2. In a similar manner, cut and glue the other two 1/8"
dowels in position.
Note: If you examine the fuse plan you will notice that there
are 1/8" balsa filler pieces in the area in front of the fin. The
purpose of these pieces is to make the fuse easier to cover
and enhance the scale appearance.
3. Fit and glue the die-cut 1/8" balsa filler pieces
between the dowel stringers and fin and the dowel stringers
and aft deck base.
4. From a leftover piece of 3/16" balsa, cut a piece to fit
between the fin LE and the top dowel stringer. Glue it in
place and sand the top edge to a rounded shape to match
the fin LE.
