Install the Aileron Pushrods and
Control Horns
❏
1. Locate the two nylon torque rod connectors.
Screw them onto the aileron torque rods approximately
half way down the threaded rod.
FasLink
2-56 (.074") Pushrod Wire
Servo Arn
❏
2. Locate two 6" [152mm] .072 wire pushrods
threaded on one. Put a silicone clevis keeper over
each of the wires. Install a nylon clevis on each wire
approximately 20 turns and then install the clevis
onto the torque rod connector. Center the ailerons
and the servo arm. Align the wires under the arms of
the servo arm, mark the location where it crosses the
hole in the arm and then bend the wire on the mark.
Install the wire onto the servo arm with a nylon
Faslink. Cut off any excess wire extending beyond
the Faslink more than 1/16" [1.6mm].
Scale Details
Looking at the photo on the box you will see that we
added a few extra details to our model. They are not
necessary for any structural integrity but we felt they
added a bit of nostalgic detail that you might want to
consider adding to your model.
Kingposts and Flying Wires
❏
1. The open area at the rear of the fuselage has the
appearance of being rigged with wire. You could choose
to actually rig this area with a lightweight wire but we
used an elastic cord that you can easily obtain from a
fabric store. (This round cord is often used for making
elastic cuffs in a sleeve or pant leg). The benefit of the
elastic is that they always stay under tension and do not
sag like wire can, plus they are much easier to install.
Start by gluing one end of the elastic cord to one corner
with CA glue. With a little tension, pull the cord to the
next corner and glue it in place. Continue this until you
have formed an “X” pattern inside each of the formers
on the top, bottom and side.
❏
2. On the top of the wing and the bottom of the
fuselage we have installed the kingposts. The kingpost
on top of the wing are made from four 1/4" x 4-1/2"
[6mm x 115mm] hardwood dowels (not included in
the kit). The kingpost on the bottom of the fuselage is
made from four 1/4" x 2-1/2" [6mm x 64mm] dowels.
The dowels are cut at an angle and glued together
where the four dowels meet. The bottom of the post
is sanded to match the surface of the wing/fuselage.
The dowels should be glued together and glued to
the wing/fuselage with 6-minute epoxy.
Cotter pin
❏
3. The flying wires are also made from the same
elastic cord and the installation is similar to the tail
structure. Drill a small hole in the top of the kingpost
on the wing. Make the hole large enough to accept a
small cotter pin. We used a small brass cotter pin
from a Robart hinge but you can also find small ones
in a hardware store. Glue the cotter pin into the
Kingpost so that the small loop faces out towards
each wing tip.
❏
4. You may recall when building the wing that there
were four blocks installed in each wing half to attach the
wire to. Locate the previously drilled 1/16" [1.6mm] hole
in each of the blocks in the top of the wing. Punch a
hole in the covering with a T-pin through the hole in
each of the four blocks. Cut a piece of the elastic cord
that is long enough to reach from the blocks closest to
the leading edge of the wing. Apply a drop of thin CA to
the tip of the elastic cord and roll the tip in your finger.
The cord will stiffen from the glue and can then be
easily inserted into the hole in the block. Insert the
stiffened cord into the hole you drilled in the block.
Apply a drop of thin CA to keep it in place. Feed the
cord through the cotter pin in the top of the kingpost and
then stiffen the end of the cord and insert it into the hole
in the other wood block. Repeat this for all four wires in
the top of each wing half.
