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.
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.
Open up you kit and inspect for damage and / or missing parts.
Use the Parts List on page 5 to verify that your kit is complete.

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: 2013.09.15.v004a 10
…. 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.
Chose Flaperon Wing Type - this will
allow you to mix up and down aileron
with elevator and to use Flaps, more
detail on that later in the manual.
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
-
mark the servos
Fold all the hinged parts over onto
themselves and let sit for an hour
or so.
Locate the control rods and snap links.
After these are glued together, they
must dry for at least 24 hours, so build
them now.

Rev: 2013.09.15.v004a 11
Once the glue is tacked up bring the
two halves together, make sure that the
dimples and spar slots line up with
each other
Remove all the little pieces from the cut
outs in the wing halves. Do not remove
the tabs in the wing spar slot at this
time
Attach one of the snap links to the end
of the glue coated rod. Note that the
snap link has a small saddle that will
craddle the rod. Repeat for the other
rods and set aside to dry for 24 hrs
Apply a medium bead of Welders to one
edge of the wing halves.
Dip the end of the control rod approx
1/2" into the Welder's nozzle to achieve
a nice even coat of glue.
Bring the two pieces together, then
seperate. Repeat this 2 or 3 times until
the glue is evenly distributed on both
edges... let the glue tack up for about 5
minutes.

Rev: 2013.09.15.v004a 12
Remove the webbing from the spar slot.
Spread the slot apart and test fit the
spar.
Rounding the ends of the spar will help
it slide into the slot a little easier.
Coat both sides of the spar with a
medium bead of Welders
Install the spar into the wing slot, make
sure you have a good solid bond
between the wing and spar. Weigh
down or push pin down to work
surface.
While the Wing is drying, install the
landing gear sturts to the fuselage
halves as shown. Use the tack up
method.

Rev: 2013.09.15.v004a 13
One fueslage half gets split as shown. It
is the one that has the little tick marks
at the center of each tab.
Locate the four landing gear strut
spars.
Test fit. Force glue into the provided
slot and lay carbon spars in as shown.
Note that on one side the spar sticks
out. Also, keep the lengths at the LG
end so the stick out the same amount.
Put a little weight on the parts and let
the glue dry.
Build the wheel assemblies next. Break
all the parts out of the Wheel Wood Kit.
Note that each tire will have two donuts
and one solid epp piece.
Spread an even coat of Welders on the
mating surfaces. Assemble while the
glue is wet so that you can make
adjustments for axle alignment.

Rev: 2013.09.15.v004a 14
While the glue is still wet on the EPP
pieces, install the wood hubs on the
front and back, again wet and with a
medium coat of Welders.
Install one of the axles thru the center
of the hubs to insure the concentricity
of all the parts. Adjust by sliding the
parts around as necessary
Repeat with the other wheel and set
aside under some weight to dry.
Once the carbon strips have dried in
the struts, test fit the little axle holders
into the ends. Note that they are not
symetrical.
Let the finished assmbly dry for a bit.
We will wrap this area with thread and
glue in a later step.

Fit the right lower fuselage part
together with the full fuselage side.
Note that the spar from the right side
sticks thru the hole....
.... and behind the spar of the full
section. The foam tab and slots should
line up better with the spars situated in
this configuation.
Fully engage the tabs and slots, taking
note of how it all goes together.
Continue to test fit the upper fuselage
half, taking not of how the open spar
fits into it's slot as the EPP tab and
slots are joined together.
Check that everything fully seats into
their respective areas and that the
orientation of parts matches the
manual photos
Make sure the pieces all match together
at 90 degrees to one another. Now that
you know how it goes together dis-
assemble and glue all the mating
surfaces per the next couple steps.

Rev: 2013.09.15.v004a 16
Apply glue to all the mating surfaces of
the lower fuselage section as well as all
the mating tabs and surfaces.
With the nozzle of the Welder's tube,
force a small bead of glue into the slot
fo the strut spar.
Fit together as per the test fit
remembering to keep the free end of the
one spar behind the one in the full
fuselage section. Make sure all is
square and fully seated.
Fit the top fuselage section together as
in the test fit and make sure all joints
and tabs are fully seated.
Make sure everything is square. Let this
assemlby dry for about an hour before
handling.
One the glue on the fuse has set up
enough to handle, remove any extra
length of the spar from the end of the
landing gear as shown.

Rev: 2013.09.15.v004a 17
Loosely fit the axle and one of the hex
nut shaped wood piece as shown above.
Note that some sticks out to the inside
and that it angles down to the work
surface as shown.
While in this position apply some
Welders and allow it to set up for a
couple hours. If in a hurry CA could be
used. Repeat for the other side.
Top View of axle alignment.
While the Axles are drying, you can cut
appart all the little foam pieces, and
install the elevator spar.
Completed View. Add additional
Welders for full coverave of the whole
area as needed. Note - Keep the axle
area where the wheel mounts free of
glue. Repeat for other side and let dry.
When the glue has set up enough to
handle, soak the axle area behind the
nut with Welders and wrap with thread.

Rev: 2013.09.15.v004a 18
All the pieces seperated and ready for
assemlby in later steps
Check fit of the elevator spar, then with
the Welder's nozzle, force a small bead
of glue into the slot for the elevator
spar.
Install the spar, wipe away any extra
glue and set aside to dry.
Locate the fiberglass motor mount and
roughen up the back side with some
course sandpaper or a file.
Apply a medium coat of Welders to the
roughen side of the mount....
.... and to the mating surface on the
nose of the fuselage. Let the glue tack
up for 10 minutes.

Rev: 2013.09.15.v004a 19
Once the glue has tacked up, stick it to
the mating surface on the nose.
The small cowling part is next. Seperate it from the larger part, and
glue to the nose, directly behind the
motor mount. This can be installed wet.
Tail Control Horns. There are two the
same, these are for the aileron, the
single shorter one is the elevator, and
the longer single one is the rudder.
Squirt some Welders into the slot and
install the horn as shown, flush with
the top, wipe away any extra glue.
Check on the under side that the
contour of the horn matches the
contour of the horn, they should be
flush, doing this ensures that the hole
in the horn aligns with the hinge line.

Rev: 2013.09.15.v004a 20
Repeat the process with the Rudder
Horn.
Make sure that the contour of the
horn
matches up with the inside of the hinge
for proper horn alignment.
The two remaining horns are for the
ailerons. They will be installed from the
underside of the wing.
For mild control throws, install the
horn so that it is flush with the near
side as shown, or the underside of the
wing.
For Wild and 3D contro
l throws, install
the horn so that it is flush with the far
side as shown, or the top of the wing.
Test fit the elevator and rudder
together. These two pieces will be glued
together BEFORE attaching to the
fuselage.
