Horizontal Stabilizer Assembly
1. Pin S1 to the board. Cut the stab leading edge from
3/8 x ¼ balsa stock and pin in place. Cut the stab
trailing edge from ¼ x ¼ balsa stock and pin in place.
Glue all the pieces.
2. Cut the stab stringers from ¼ x ¼ balsa stock and
glue in place.
3. Sheet the top of the horizontal stabilizer using a
piece cut from 1/16 x 4 x 36 balsa sheet.
4. Cut a slot in the sheeting to match the slot in S1. This
will align the vertical stab during assembly.
5. Sheet the bottom of the horizontal stab.
6. Sand the leading edge to shape and sand all the
edges smooth.
1. Pin S2 and S3 to the board. Cut the stab trailing
edge from ¼ x ¼ balsa stock and pin in place. Glue
all the pieces.
2. Cut the stringer and top support from ¼ x ¼ balsa
stock, pin in place, and glue.
Vertical Stabilizer Assembly
3. Sheet both sides of the vertical stab. So not sheet
the tab on S2.
4. Sand the leading edge to shape. Sand all the edges
smooth.
1. Glue E2 into the slot in E1. Guides for the rib are
etched into E1 for reference.
2. Repeat for E3, E4, E5, E6 and E7. See Figure 5.
3. Bevel the trailing edge of E1 to match the taper of
the ribs.
4. Fill the inboard space between ribs E2 and E3 with
scrap balsa and sand even with the ribs. This will
provide strength for the elevator joiner wire and con-
trol horn mount.
5. Note that all E1s are marked for location. Glue the
respective E1 to the previous assembly, aligning all
the ribs into the slots.
6. Cut the elevator leading edge from ¼ x ¼ balsa
stock and glue into the channel in the elevator
assembly. Make sure the edges of E1 attach firmly to
the leading edge. Sand all edge smooth.
7. Glue the elevator horn to the end of the elevator
assembly.
8. Repeat for the remaining elevator.
