Tools shown and listed are suggestions only. Depending
on your building technique you may not need everything
indicated – and/or – you may find that other tools
available to yourself may be of benefit to your Build.
It is also recommended that you have a flat building
surface, one that will accept stick pins and push pins.
An Acrostic Ceiling panel from your local hardware store
fits this bill nicely, and will lay flat on your work table.
Over size / long push pins are available at your local
craft store. These two items are by no means required,
but will aid in the building process, and can be used for
future projects.

THE BUILD
THE BUILDTHE BUILD
THE BUILD
CONSTRUCTION METHODS:
Building surface should be at least 2ft x 4ft and flat. Weights or some small heavy objects will be handy for holding things in place during
the time glue is setting.
Welders glue is the primary adhesive used for this build. The Rod Guides and End Links use thin CA with Applicator and Activator. When
using the Welders glue for a butt joint, apply a thin film to each surface, allow to sit for approx five minutes and then assemble.
Note that this method will create a nearly instant bond, so locate carefully when bringing the two pieces together. If alignment is
necessary or a slip joint, do not allow the glue to tack up, simple apply and join immediately, you will have several minutes to locate the
two parts before the glue sets up. In most cases the parts being glued can be handled with care in 30 minutes, full cure is approx 24
hours.
Open up your kit and inspect for damage and / or missing parts.
Use the Parts List on page 5 to verify that your kit is complete.
Do the same with the Power Set, confirm that you have all your
items and that they appear to be in sound condition. Testing of
functionality will be one of the first steps that will follow shortly.

Program the Throttle End Points per the
ESC Instructions and next couple steps….
Identify the porper pins for the; Throttle,
Aileron, Elevator and Rudder Channels.
Carefully compare to the diagram to make
sure you have the correct orientations.
Compare your Reciever to the included
diagram from the side as shown above.
Make a note of the polarity of the pins. In
most cases, either Black or Brown is used
to identify Negative -).
Make a new program in your Radio. Zero all
the Trims and Subtrims. For starters all the
ATVs can be set to 100% . Adjustment of
additional settings will be done at the end
of the build.
Plug Motor wires into the ESC, the ESC into
the Throttle Channel, and the servos to
their appropriate channel. Bind per your
Radio’s Instructions.
turn on your radio and move the throttle
stick to "full throttle" position...

Rev: 2013.10.19.v002b

…. reconnect the battery to the ESC
and listen for two quick short beeps,
immediately following the beeps,
move the Throttle stick to low
position.
Next you should hear a series of
tones to indicate that programing is
complete.
Re-
bind the system and double check
correct operation of all components.
Center all servos as close to 90 deg
as possible. Install the Longest single
arms on the servos.
Fold all the hinged parts over onto
themselves and let sit for approx ten
minutes
Mark the Servos with their channel and
install the horn screws
Locate and position the four pieces
shown above
Program your radio so that the
channels & directions match the
picture above. Installed horns as
shown, dbl check that subtrims - arms
should be at 90 deg

Rev: 2013.10.19.v002b
11
Remove the webs from the areas where
the Side force generators will install
Apply a medium bead of Welders to one
of the pieces of each joint
Join and separate each joint a couple
times to evenly distribute the glue onto
both surfaces, set aside to tack up
While this is tacking up, do the same
with the canopy and fuselage. Also
locate the short carbon strips and test
fit them into their slots.
It may be that the slots need to be
made a little deeper for a flush fit.
Apply some glue into the slot and
install the strips. Weigh down flat and
let dry
Set these aside for while the glue tacks
up for the canopy joint

Rev: 2013.10.19.v002b
12
Test / Dry fit the rib and spar pieces,
with the exception of the bumped
areas, everything should be flush with
the bottom of the wing.
By now the glue for the fuselage
horizontal fuselage sections should be
tacked up. Carefully bring them
together, the bond will be instant
Next is the carbon inlays. Locate the
longest strip, the four 225mm rounds
and the wood kit
Find the pre-made slo
ts and cuts for all
the pieces. Notice how the wood rib is
different from front to back
Check that the slot for the Wing Spar is
deep enough, should sit flush. If not
you can gently drag the end of the spar
across the slit to increase the depth
until deep enough
Make sure the slot in the rib allows for
an easy fit of the spar. Enlarge if
necessary with a hobby knife if
necessary

Rev: 2013.10.19.v002b
13
Next test fit the "X" brace pieces into
the slits of the aileron. Note, at the
intersection point one will be a little
deeper then flush
By now the Welder's should be tacked
up on the Canopy. Carefully bring the
two pieces together, lining up the front
and rear points
Back to the wing... remove the pieces
for the "X" brace, and with the tip of the
Welder's tube as show, force a small
amount of Welders into the slit.
Repeat this process for the other aileron
and the wing spar/rib parts. Weigh
down the assembly and allow to dry
Long Push pins could also be used if
you building surface allows for it.
Shown here is an acoustic ceiling tile
on flat surface covered with Parchment
paper
Lay the rod in, and press to flush, wipe
away any extra glue that is forced out

Rev: 2013.10.19.v002b
14
Test fit your aileron servo into the
provided cut out. You may need to
enlarge it slightly
If your building board allows for it,
make a small pocket so that the servo
will sit flush on it's ears, otherwise just
hang this part over the edge of the table
Locate the Differential horn from the
plastic kit and 2 sets of the quick links.
Install the quick links into the holes
and secure with the keepers
Once the quick links are installe
d apply
a generous amount of Welders to the
top surface of the servo arm and then
attach the Diff Horn on top of, and
centered as shown, allow to dry.
Locate the small halve moon wood
parts. Note that the notch in the wood
will line up with the notch in the foam.
Off center hole in the wood is to the
rear of the plane
Glue the wood pieces to the fuselage
using the tack up method, making sure
the orientation and notches are correct
and lined up

Rev: 2013.10.19.v002b
15
Once the glue is dry on the aileron
differential horn, fit the lower fuselage
section as shown
It may be necessary to slightly enlarge
some areas to allow for a nice fit
Do the same for the for the rudder
servo. Make sure the cut is deep
enough and notch to allow clearance for
the servo wires
Apply a thin bead of Welders to the butt
joint areas on the bottom of the
horizontal fuselage sections. Note - no
glue in the slots at this time
With a small piece of paper or thin
cardboard, spread the bead out into a
thin even layer
Apply glue in the same fashion to the
butt joint area of the lower vertical
fuselage section. Note - no glue on the
tabs at this time

Rev: 2013.10.19.v002b
16
Spread the glue bead out as you did on
the mating part, avoiding the tabs. Set
aside and let both parts tack up
While those parts are tacking up, locate
the ailerons control rods 150mm) and
tail control rods 500mm)
as well as the
two tail servos, horns and snap links as
shown above
Start by clipping the snaps links from
the molded tree. Use a small pair of
flush cutters or hobby knife
Dress up the end of the push rod that
you will be gluing the snap link to.
Make sure that the end is nice and
round, not crushed out from the
cutting process
Check to verify a nice fit of the rod into
the saddled area of the snap link
Take the finished end of the rod and
poke it into the glue nozzle to coat with
glue, it may be necessary to do this a
time or two for an even coat of glue

Rev: 2013.10.19.v002b
17
Once there is an even coat of glue,
attach it to the saddle area of the snap
link and set aside to dry. Repeat with
the other three control rods
Test fit the aileron control horns. Make
sure and use the one that is shown
above and that the hole will be inline
with the hinge/pivot point
Force some glue into the slit with the
tip of the glue nozzle
Install the horn, making is flush with
the bottom surface and making sure
that the hole is directly above the hinge
line. Wipe away any extra glue. Repeat
for the other side
Install a quick link into the outer most
hole of the longest single sided servo
arm.
Press the keeper ring on, make sure the
quick link can rotate freely. Repeat for
the other tail servo

Rev: 2013.10.19.v002b
18
Back to the Fuselage pieces... add some
glue to the tabs and slots
While the glue is still wet on the tabs
and in the slots, join the two pieces
together. Make sure the nose area is
flush
Since part of the joint was tacked up,
the bond here will be instant. Press the
pieces together firmly and make sure
there are no gaps
Wipe away any extra glue. Remember,
for this airframe, the lighter the better,
so remove any extra glue
Make sure everything is square. It can
still be tweaked a little from side to side
if necessary
Next is the foam trusses. Start with the
right underside truss, add a thin bead
of Welders to the entire length of the
beveled edges

Rev: 2013.10.19.v002b
19
Install the right under side truss as
shown... use stick pins if necessary to
hole the truss in place while the glue
dries
Repeat for the Left under side truss,
but do not put glue all the way to the
pointed end, see next picture
Leaving this area free of glue will allow
you to tuck all the radio wires away and
out of site later in the build
Bottom Carbon Trussing is next. Find
the four 200mm rods and the two
165mm rods. A .040" dia drill and pin
vise will come in real handy. Read the
next couple steps before proceeding
Dress up both ends of all the rods so
that they are sharply pointed
With the drill, chase the holes in the
wing rib as shown, using the approx
angle that the rod will be installed in for
best results and fit

Rev: 2013.10.19.v002b
20
Repeat for the other wing rig hole Do the same for the mating holes on
the doubler on the fuselage
Once far enough in, line the other end
up with the mating hole in the fuse
double, then back out slightly so that
the fuse end is engaged about half the
foam thickness
Repeat for the other three long pieces.
Note - no glue yet at this point.
Sight down the fuselage, and adjust for
squareness if needed
Stick the carbon rod thru the hole in
the rib, and while holding at the right
angle, twist and poke that end into the
foam far enough to clear the fuse hole
