SAFETY NOTES
SAFETY NOTES
SAFETY NOTESSAFETY NOTES
Before assembling and flying this model, read carefully any
instructions and warnings of other manufacturers for all the
products you installed or used on your model, especially radio
equipment and power source.
Check thoroughly before ever 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 flan on a hard surface, this will allow the
airframe to straighten out if lightly bend from
shipping. Do not worry since EPP is very pliable and
can be bend back if bend out so shape easily.

32” airframes is very similar and can be built
with this manual.
Wing / Nose / Elevator
Glue the left and right wings, fuselage
center section, nose piece and elevator
together. Start by laying all needed parts
on a flat table, test fit, noticing the
different size tabs before gluing
Keep the slot in the main wing clear of
glue and open, so that it can accept the
main spare
Glue each part together than apply a few
weights on the top of each to ensure each is
sitting flat and connected while drying.
Right after gluing, make sure the wings are
square to the fuselage center section and
measure from the tips of the elevator to the
tips of the wing, and make equal. This will
ensure proper orientation between wing
and elevator
Coat both sides of the spar with Welders
glue. Spread the foam and lay in the spar.
Use tape weight or stick pins to make sure
the joint is held firm until dry

or electronics hook everything up and test
for proper function. Also at this time note
the center locations of all servos and attach
the quick links to the horns as shown.
Determine which servos will be used for
the Elevator and Rudder and attach the
horns accordingly, doing this now is less
tedious than doing it after the servos are
glued in.
Elevator Servo - (5g)
Glue with Welders or Hot Glue
Aileron Servo – (9g)
With the nose of the aircraft hanging off
the work surface, locate the aileron servo in
position as shown. Cut/remove the lower
fuselage clearance slots for both the aileron
and elevator servos as shown below
With the bottom of the plane facing up,
locate the Elevator Servo as shown. Trace
around the servo and remove the necessary
foam for it to fit snuggly in position. If you have
chosen to install the servo horns, gently move
the arm so that it is parallel to the servo, and
allows the servo to lay flat in the cutout
Insert and glue aileron servo into place,
make sure the servo tabs sit flush with the
bottom of the main wing. Now the lower
fuselage can be glued to the wing / elevator
assembly
Rev: 2012.04.23a 9
Fuselage Truss
Locate the 2 fuselage truss strips. Note
that the parts are beveled to fit flush at 45
degrees when installed
Test fit the Truss members on the
underside of the airframe. They should be
centered roughly between the aileron servo
and the elevator control surface relief cut
out. Before gluing, notice that the flat
section is toward the elevator as shown. At
this time you could also consider how your
servo wires will be routed and situate them
under the trusses
Situated the nose of the aircraft beyond the
work surface to provide clearance for the aileron
servo and allow the airframe assembly to lay
flush on the work bench
Glue the truss strips to the fuselage. It will
be necessary to secure the strips in place
while the glue is drying. Stick pins or
small tacks of hot glue work will for this

1. Sand the end of the z-bend wire
that will be attached to the carbon
rod. Use rough sand paper
2. Lightly sand the end of the carbon
rod in the area where the wire zbend will be attached
3. Wipe/clean the sanded areas of
each part with a cloth dampened
with alcohol
4. Position the z-bend wires on the
ends of the rod. Before applying
the CA, the wires can be held in
place with a small alligator clip or
a couple small pieces of shrink
tubing slid into position and
shrunk to hold
5. Apply CA and hit with kicker
6. Slide a piece of shrink tubing long
enough to cover the wire and
shrink to fit
7. Repeat process the other short rod

CAUTIONCAUTION
Do not over tighten the quick link screws,
they will cause damage to the carbon rods
if made too tight. To get a feel for how
tight to make them, experiment on part of
the extra length. Also if the ends of the
screws have any burrs or sharp edges,
carefully sanding these off will help to
prevent the screw from “digging” into the
carbon rod
Note
Note:::: there are many different techniques
NoteNote
for attaching the z-bend wires to carbon
rods. The important points are to make
sure the areas to be glued, have been
roughed up with sand paper and are
cleaned thoroughly before gluing. Equally
important is to make sure the CA does not
run into the control horn holes, if possible,
situate the airframe so that the glue tends
to run in the opposite direction
Installing Aileron Push Rods
Insert the z-bend end into the aileron
differential horn as shown
Slide the bare end through the easy
connector as shown. It may be necessary to
shorten the rod slightly so that while
deflecting the aileron control surface the
rod can slide through the easy connector
hole. Trim as desired, leaving approx ¼”
for adjustments and strength
Rev: 2012.04.23a 16
Motor Mount
Prep the surface to be glued. Use medium
grit sand paper, clean with alcohol
Using Welders’ glue, evenly coat the
prepped side of the motor mount and the
mating area on the nose of the fuselage.
Let sit for 1 minute before attaching
Install the motor using the provided
hardware in such a way that the wires will
be on the same side as you have chosen to

Control Surface Centering
It is important to note that control surface
centering will be effected by ambient
temperature. EPP foam will expand and
contract when the temperature changes,
which in turn will change the position of the
control surface. This is normal and NOT the
result of a faulty servo. If flying in fluctuating
temperatures, simple adjust the trim before
each flight.

The first flights should be done with the
CG at the recommended position, and
reduced control rates until comfortable
with your handling of the aircraft. As your
experience with the aircraft grows
experiment with different CG points and
control rates. After all flights, check the
aircraft over for damage and/or other items
that may adversely effect flight
performance.
The 32” Airframe is full 3D capable EPP
plane and will take anything you throw at
it, including the occasional crash. If, as
the result of a crash, the foam tears, simple
glue with Welders or CA. Many pilots
prefer Welders because it remains flexible
after drying. CA however, is more suited
for the “quick” repair.
These planes can be flown indoors or
outdoors. It is the perfect size for the
neighbor park, large backyard, gymnasium,
or indoor arena, allowing for plenty of
opportunity to fly and learn new
maneuvers. This aircraft is a great stand
alone plane, or training aid to perfect
routines to be done with larger aircraft.
This EPP plane should be hung from it’s
prop when not in use, doing otherwise
could cause the airframe to twist. Storage
in a hot car could also cause damage.
