4. Working carefully without cutting into the balsa, use
your heated soldering iron or a sharp hobby knife to cut the
covering from the sides of the fin and the top of the
fuselage. Make sure you cut just inside the
lines–approximately 1/32" [.5mm]–so that none of the balsa
will be exposed when all the parts are joined.
❍
5. Use one of your paper towel squares moistened with
denatured alcohol to wipe away the ink lines.
❍
6. Use 30-minute epoxy to glue the fin to the fuselage
with T-pins to hold the fin in position. Before the epoxy
hardens use a builder’s square to check to see if the fin is
perpendicular to the stab. If necessary, use tape to pull the
fin over to one side or the other to get the fin vertical. Allow
the epoxy to harden before proceeding.
❍
7. Take out the T-pins. Glue the tri stock braces into position
with 30-minute epoxy using T-pins to hold them in place.
❍
8. While you have some epoxy mixed, glue in both
wing dowels.
Hook Up the Controls
❍
1. Cut one of the wire pushrods to a length of 27"
[685mm] by cutting off the non-threaded end. Cut the other
pushrod to a length of 29-3/4" [685mm].
❍
2. Thread one of the pushrods halfway into one of the
clevises–this should take about fifteen full turns. Cut the
mounting plate off one of the control horns. Slide a silicone
retainer over the clevis, then connect the clevis to the third
hole out from the bottom of the horn. Prepare the other
pushrod the same way.
❍
3. Slide the longer pushrod into the elevator guide tube in
the fuselage. Mark, then drill 3/32" [2.4mm] holes through
the elevator for the two elevator horn mounting screws.
Mount the elevator horn with two 2 x 10mm screws and the
plastic mounting plate.
