In this step I will outline the procedure we use to install the hinges. There are several ways to do this
and several adhesives you can use. We will describe the way we do it, as this method has proven itself
over many years of model building. If you are new to this type of hinging process then I recommend that
you install a single hinge first just to acquaint yourself with this method.
Before starting the process get a few items together that will aid you as you proceed. You will need the
following items: 30 minute epoxy (we recommend Pacer Z-Poxy), a scrap piece of pushrod or 1/8” dowel,
paper towels and denatured alcohol. Pull the stab/elevator apart and remove the hinges. You will need to
cut 2 hinges just beyond the second knuckle to clear the fiberglass tube socket in the stabilizer. Insert the
carbon fiber wing tube into the socket while testing for proper hinge length to avoid damaging the
fiberglass sleeve. Mix a generous batch of 30 minute epoxy. Use the pushrod or dowel to thoroughly coat
and fill the hinge hole with epoxy, then coat the hinge with epoxy. Push the hinge into its hole until the
joint is about a ¼” from its final position and use a paper towel to remove the excess epoxy that has been
forced from the hole. Push the hinge the rest of the way in and make sure the hinge pin is centered in the
hinge line. Use some denatured alcohol and a paper towel to remove all excess epoxy, especially on the
hinge pin. When you are satisfied with
the result set the surface aside to dry. Position the drying piece so
that any excess epoxy will pool around the rear of the hinge. When you are comfortable with this process
you should be able to do one side of a surface per batch of epoxy. Glue all hinges into the stabilizer first.
After the glue has set trial fit the elevator to the stab and adjust if necessary. There should be as little gap
as possible between the stab and elevator. When satisfied with the fit remove the elevator and repeat the
gluing process outlined above. Be sure to wipe away all excess epoxy! Set aside to dry. Repeat this process
for the other stab/elevator half. Please see the following series of pictures that will aid in visualizing this
process.
