7. Insert three hinges in the rudder and attach the rudder to
the fi n. Remove the pins, making sure there is approximately
a 1/64" [0.4mm] gap between the rudder and fi n.
Assemble, then Apply 6 Drops
of Thin CA to the Center of
the Hinge, on Both Sides
8. Defl ect the rudder 1-1/2" [38mm] in one direction and
apply six drops of thin CA to the center of the hinges. Defl ect
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
fi n. Use a square to check that the stabilizer is perpendicular
to the fi n.
3. Position the two stabilizer supports under the stabilizer
against the fi n. Mark the outline of the supports on the fi n
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 fi n and stabilizer.
5. Install the elevator using the same hinging method used
on the rudder.
