7. Insert three hinges in the rudder and attach the rudder to
the fin. Remove the pins, making sure there is approximately
a 1/64" [0.4mm] gap between the rudder and fin.
Assemble, then Apply 6 Drops
of Thin CA to the Center of
the Hinge, on
Both Sides
8. Deflect the rudder 1-1/2" [38mm] in one direction and
apply six drops of thin CA to the center of the hinges. Deflect
the rudder in the other direction and again apply six drops
of thin CA to the center of the hinges. Use a paper towel to
absorb excess CA from the hinge gap before it hardens. Do
not use CA accelerator. Allow the CA to harden slowly.
INSTALL THE STABILIZER
1. Draw a centerline on the bottom of the stabilizer. Draw
a line 3/32" [2.4mm] on each side of the centerline. Use a
hobby knife to cut and remove the covering only between the
two outside lines.
DO NOT cut the wood under the covering
as this will weaken the stabilizer, causing it to fail.
2. Use 6-minute epoxy to glue the stabilizer to the
top of the fin. Use a square to check that the stabilizer is
perpendicular to the fin.
3. Position the two stabilizer supports under the stabilizer
against the fin. Mark the outline of the supports on the fin
and stabilizer. Use a sharp hobby knife to trim and remove
the covering 1/16" [1.5mm] inside the outline.
4. Use 6-minute epoxy to glue the stabilizer supports to
the fin and stabilizer.
5. Install the elevator using the same hinging method
used on the rudder.
