14. Cut the tips and roots from the balsa sheet.
Glue them to the die-cut cores. Glue the stab tips to
both ends of the stab and elevators and shape them
the same way you did the fin (in two stages: first
sanding the tips to match the stab and elevator, then
by rounding the tips).
Finish the stab and elevators
❏
1. Use a ballpoint pen to mark the elevators in an
inconspicuous location as “L” and “R.” Cut the
elevators from the stab. Sand the tips and rib stubs
even with the elevators and stab.
❏
2. Glue the elevator root blocks to the elevator.
Sand the fronts of the blocks even with the LE spars.
Cut the elevator leading edges from the 1/4" x 3/4"
x 30" [6.4 x 19.1 x 762mm] balsa stick, then glue
them to the elevators.
❏
3. Shape the elevator LE’s and the root blocks
even with the elevators.
❏
4. Cut the hinge slots. Shape elevator leading edges
to a “V” to achieve 5/8" [16mm] of control throw.
❏
5. With the elevators temporarily joined to the stab
with the hinges, center the elevator joiner wire on
the elevators as shown on the plan. Use a ballpoint
pen to mark the location of the joiner wires on
the elevators.
❏
6. Drill a 1/8" [3.2mm] hole in both elevators for
the joiner wire.
❏
7. Cut a groove in both elevators to accommodate
the joiner wire. Hint: Use a Great Planes Groove
Tube (GPMR8140) or a 1/8" [3.2mm] brass tube
sharpened on one end to cut the grooves.
❏
8. Test fit the elevators to the stab with the joiner
wire. If necessary, bend the wire so the elevators
align with each other. Note: If you found it necessary
to bend the wire, note that it must be reinserted into
the elevators the same way when it’s time to glue it
in. If this is the case, file a small notch in the right
side of the joiner near the end.
❏
9. Round the elevator root blocks.
