4. Glue the joiner wire in the elevator halves with 6-minute
epoxy. Before the epoxy cures, apply 6 drops of thin CA
adhesive to both sides of each hinge. Allow a few seconds
between drops for the CA to wick into the slot. Use a paper
towel to wipe off any excess CA that may have gotten onto
the covering.
Do not use accelerator on any of the hinges. Do not
glue the hinges with anything but thin CA and do not
attempt to glue one half of the hinge at a time with medium
or thick CA. They will not be properly secured and the
controls could separate while the model is in flight.

C. It is best to leave a very slight hinge gap, rather than
closing it up tight, to help prevent the CA from wicking
along the hinge line. The gap is large enough if you can
just start to see light through it. Make sure the control
surfaces will deflect to the recommended throws without
binding. If you have cut your hinge slots too deep, the
hinges may slide in too far, leaving only a small portion of
the hinge in the control surface. To avoid this, you may
insert a small pin through the center of each hinge before
installing. This pin will keep the hinge centered while you
install the control surfaces.

B. Drill a 3/32" [2.4mm] hole 1/2" [12.7mm] deep in the
center of each hinge slot. A high speed Dremel Tool
works best for this. If you use a regular drill, clean the
hinge slots with your hobby knife.

A. Cut the covering from the hinge slots–don’t just slit the
covering but remove a small strip the size of the hinge.
INSTALLING CA HINGES
The hinge material supplied in this kit consists of a 3-layer
lamination of mylar and polyester. It is specially made for
the purpose of hinging model airplane control surfaces.
Properly installed, this type of hinge provides the best
combination of strength, durability and ease of
installation. We trust even our best show models to these
hinges, but it is essential to install them correctly. Please
read the following instructions and follow them carefully to
obtain the best results. These instructions may be used to
effectively install any of the various brands of CA hinges.
The most common mistake made by modelers when
installing this type of hinge is not applying a sufficient
amount of glue to fully secure the hinge over its entire
surface area; or, the hinge slots are very tight, restricting
the flow of CA to the back of the hinges. This results in
hinges that are only “tack glued” approximately 1/8" to
1/4" into the hinge slots. The following technique has been
developed to help ensure thorough and secure gluing.
