manufacturers for all the products you installed or used on your model, especially radio
equipment and power source.
Check thoroughly before every flight that the airplanes’ components are in good shape and
functioning properly. If you find a fault do not fly the model until you have corrected the
problem.
Radio interference caused by unknown sources can occur at any time without notice. In such a
case, your model will be uncontrollable and completely unpredictable. Make sure to perform a
range check before every flight. If you detect a control problem or interference during a flight,
immediately land the model to prevent a potential accident.
Youngsters should only be allowed to assemble and fly these models under the instruction and
supervision of an experienced adult.
Do not operate this model in a confined area.
Do not stand in line with, or in front of a spinning propeller and never touch it with any object.
IMPORTANT: PRIOR TO ANY ASSEMBLY
Please Note: after removing kit from shipping box, lay each piece flat on a
hard surface, this will allow the airframe to straighten out if lightly bent
from shipping. Do not worry since EPP is very pliable and can be bent back
if out of shape.

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 you 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.

Rev: 2013.06.25.v001b 9
Make a new program in your Radio. Zero all
the Trims and Subtrims. For starters all the
ATV can be set to 100%. Adjustment of
additional setting will be done at the end of
the build.
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 -).
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.
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.
Program the Throttle End Points per the
ESC Instructions and next couple steps….
… turn off your Tra
nsmitter and unplug the
flight battery from the ESC, position the
Throttle Stick to full HIGH postion and
power on the radio…

…. 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

show in picture. Notice there should be
equal distance gaps on both sides of the
elevator. Do not press to hard or the hinge
will become to stiff
Repeat the Welder Adhesive hinge method
for both ailerons as shown in picture. We
used a razors thickness for our inter gap
Leave all 3 assemblies parts to side flat and
dry cure
