2. Bolt the wing to the fuselage. Apply 30-minute epoxy
to both sides of the stab and in the fuselage to the stab
saddle and the tail blocks. Don’t forget to install the
elevator joiner wire, then slide the stab into position. Wipe
away epoxy that was deposited on the stab with paper
towels and alcohol. The same as was done before the
model was covered, use the pin and string to align the stab.
View the model from the rear and make sure the stab is
aligned with the wing. If necessary, place weight on the
“high side” of the stab to get it to align with the wing. Allow
the epoxy to fully harden before proceeding.
❏
3. Glue the fin into position the same way. Use a Hobbico
Builder’s Triangle to make certain the fin is perpendicular to
the stab. If necessary tape can be used to pull the fin to one
side or the other to get it vertical.
❏
1. If you haven’t already done so, cut a small strip of
covering from all the hinge slots. Also cut the covering from
the grooves in the elevators and ailerons for the joiner wires
and torque rods.
❏
2. Test fit the ailerons to the wing with the hinges. If any
of the hinges don’t remain centered, stick a T-pin through
the middle of them to hold them in place.
❏
3. Apply 30-minute epoxy in the groove and in the hole in
one of the ailerons for the torque rod. Also apply epoxy to
the aileron torque rod for the aileron you are installing. Join
the aileron to the wing and the torque rod. Wipe away any
epoxy that squeezes out.
❏
4. Adjust the aileron so there is a small gap between it
and the wing–just enough to see light through or to slip a
piece of paper through. Apply six drops of thin CA to both
sides of all four aileron hinges. Wait a few seconds between
drops to allow the previous drop of CA to soak in so it
doesn’t run down the hinge gap. If you do get any CA in the
hinge gap you can soak it up before it hardens with a tissue
or a paper towel square. If any CA in the hinge gap hardens,
most of it can be picked out with a #11 blade. Any remaining
hardened CA can be cleaned out with CA debonder.
❏
5. Hinge the elevators and rudder the same way. Don’t
forget to install the tail gear before gluing in the hinges. Glue
the tail gear bearing into the fuselage with epoxy, but don’t
inadvertently glue the bearing to the rudder.
❏
6. Mount a 1" [25mm] tail wheel (not included) to the tail
gear with a 3/32" [2.4mm] wheel collar and a set screw.
Before installing the screw, apply a drop of threadlocker to
the threads.
❏
1. Cut the covering from both sides of the fuselage over
the pushrod exit slots in the guide tubes.
