INSTALLING EASY HINGES
105.
Using a No. 11 X-Acto blade (or similar) cut slots in the control surfaces approximately 1/2" in depth and slightly wider than
the hinge at the locations shown on the plans. Continue cutting all of the slots in all the places to be hinged.
106.
After all slots have been cut, insert an
EASY HINGE halfway into each slot in
one of the pieces to be hinged. DO
NOT GLUE THE HINGES YET! First
carefully slide the matching model part
onto the other half of the hinges. You'll
find it easiest to slide the part onto the
hinges at an angle, one hinge at a time,
instead of trying to push it straight onto
all the hinges at once.
107.
At this point the stabilizer and elevator
are joined on the EASY HINGES, but
the hinges are not glued. Align the stab
and elevator, then adjust the gap
between them as required. For best
control response, the gap should
generally be as small as possible but
big enough to allow the control surface
to move to the maximum deflection that
you will require.
108.
Place three or four drops of any brand cyanoacrylate adhesive (thinnest variety) directly onto the EASY HINGE in the gap.
You will notice that the glue is quickly wicked into the slot as it penetrates both the wood and the hinge. Continue this
process, gluing the same side of all of the hinges. Then turn the surfaces over and repeat the gluing process on the other
side of each hinge.
109.
After the glue has cured, approximately three minutes, the joint can be flexed. You may notice a slight stiffness in the joint.
This can be eliminated by flexing the surface to full deflection each direction a couple of dozen times. Don't worry about
shortening the life of the hinge as they are almost indestructible.
110.
Hinge the rudder to the fin in the same manner as above. However, do not glue the bottom hinge of the rudder at this time,
this will be done in the final assembly when the fin is glued in place on the fuselage.
FINAL ASSEMBLY
111.
Back in Step 10 of the fuselage construction you drill holes in the fuse sides for
the 3/16" birch dowels that hold the wing on when standard rubber band
mounting is used. Now you can epoxy the dowels in place. The wing dowels can
be painted a matching color with enamel or dope.
112.
Cut away the covering material from the bottom of the stab where it will contact
the fuselage. Then epoxy the stab in place on the fuse. Use slow drying epoxy to
allow you ample time to carefully align the stabilizer with the fuse and wing.
Check the alignment of the stab to the wing from the front and top before the glue
dries. Mount the wing on the fuselage, step back about 10 feet and view the
model from the front. Tilt the stab slightly if necessary. Use a tape measure to
insure that the wing and stab are at equal distance and parallel to each other.
Use pins to hold the stab securely in position until dry.
113.
Set the fin/rudder assembly in place on the fuselage. Cut a hinge slot in the rear
of the fuselage for the bottom rudder hinge.
