WING ASSEMBLY
Parts needed
- Roll of wing joiner tape
- Right and left wing panels
- Wing joiner (also called dihedral brace)
Step 1.1 Locate the wing joiner (also called Dihedral
brace). Using a ruler, determine the center of the wing join-
er and mark it with a pencil as illustrated in 1B.
Step 1.2 Trial fit the wing joiner into the wing panels. lt
should insert smoothly up to the center line as illustrated in
SIIETSN
1A- Left and right wing panels
Step 1.3 Apply plenty of 30 minute Epoxy to one end of the
wing joiner using a stir stick or epoxy brush as illustrated in
1D. Carefully insert the epoxy coated half of the wing join-
er into one wing panel as illustrated in 'lE.
See 1F and use a cloth or tissue to wipe away any excess
epoxy that squeezes out of the joint. Repeat this process

Step 2.4 Once the epoxy has cured completely (allow sev- supplied.Starting on the bottom side of the wing, stick the
eral hours at least), the tape can be carefully removed from tape centrally over the joint ensuring that it is pressed down
the wing panels. Peel the tape back on itself... do not pull firmly as you work around the wing. Wrap the tape all the
upright away from the wing. To seal and finish the joint in way around the wing joint in one piece, starting and finish-
the wings, a roll of wing joiner tape has been ing on the bottom.
Step 2.1 When the epoxy has cured in Stage 1, trial fit the
second wing panel onto the wing joiner first to ensure that
the two panels fit without an excessive gap.
Step 2.2 Now apply plenty of epoxy to the wing joiner and
wing root ribs of both wing panels. Use only 30 minute
epoxy to ensure a strong bond and give yourself plenty of
working time. As described in the Step 1.3, repeatedly
apply epoxy and insert into the wing joiner cavity, the epoxy
should ooze from the joint and the excess should be
cleaned off with a rag or tissue before it cures.
Step 2.3 Use low tack maskilg tape to align the wing sur-
faces and hold the two panels together until the epoxy
cures.
3A- Prepare the servos by fitting the
rubber grommets & ferrules supplied
with your seryos
2D- Apply tape over the joint starting
here on the boftom as shown
To install the aileron servos into the wing you will need the following items:
- 2 micro servos (with mouting screws control arms and grommets)
- Two aileron control rod assemblies with a clevis screwed onto both ends
- Low tack masking tape
- 2 aileron control horn assemblies
- 2 aileron extension cables 12 in (30 cm)
Step 3.1 Turn the wing upside down.
Step 3.2 Trial fit the aileron servo into the servo mounting cavity. You may have
to modify the cavity slightly to provide clearance for the servo and servo wires.
Step 3.3 Use a hobby knife to modify the cavity as required. Most servos have
their output shaft closer to one end than the other. Mount the servo so that the
output shaft is closer to the leading edge of the wing.
Step 3.4 Securely attach an aileron extension cable to the servo. Thread the
cable through the wing tube to the center of the wing. Screw the servo into place
with the screws and grommets supplied. lt is important to install the grommets
and screws correctly. See the manual that came with your radio for intructions
about your paticular servo grommets.(Note that in some type servo installation
without the grommets)
Step 3.5 Fasten the screws down according to the seryo manufacturers recom-
mended tightness.
Step 3.6 Repeat step 3.2 to 3.5 for the other wing panel.
2E-Continue applying the tape over 2F- Gontinue back around to the bgttom

INSTALLING THE AILERON CONTROL SYSTEM
Step 4.1 Consult your radio instruction manual and center
the aileron servos using either a Y connector or a comput-
er radio that accomodates the use of two aileron servos.
Turn on the transmitter and then the receiver. Center the
aileron trim lever on the transmitter. Remove the servo arm
mounting screws and servo arms.
Step 4.2 Mount the servo arms back on the servos so that
the seruo arms are parallel with the back edge of the wing.
Screw the arms into place using the servo arm mounting
screws supplied with the servos.
Step 4.3 Locate the two aileron control rods in the hard-
ware bag (see 4A). Ensure the clevises are screwed well
onto the threaded portion of the rod. Rotate and tug
aggressively on the clevises and ensure that they are not
loose on the rods.
Step 4,4Tape the ailerons into their neutral position so that
they are even with the trailing edge of the wing and not
pointing either up or down.
Step 4.5 Install the aileron control horns as illustrated in 48
and ensure they align with the servo arms.use 30 minute
epoxy .

Step 4.6 Connect the aileron servo control rods between
the aileron control horns and the aileron seryo arms as
shown in 4C.
Step 4.7 Carefully remove the masking tape holding the
ailerons.
Step 4,8 Turn on your radio and activate the ailerons, using
the aileron stick and ensure that a smooth full motion can
be achieved.
Step 4.9 With the wing top side up and viewed from the
back, ensure that moving the transmitter aileron stick to the
left raises the left aileron and lowers the right aileron.
Movement of the stick to the left will roll the aircraft to the
left. (Counterclockwise roll of the wing when viewed fr:om
the back).
Step 4.10 With the wing top side up and viewed from the
back, ensure that moving the transmitter aileron stick to the
right raises the right aileron and lowers the left aileron.
Movement of the stick to the right will roll the aircraft to the
right. (Clockwise roll of the wing when viewed from the
back).

FINAL RC SET-UP
Before starting the final set-up of the model, switch
on the radio and ensure that all trims are in their
neutral positions. Check that the ailerons, elevator
and rudder are centered. lf any adjustments are
needed, do these by uncoupling the relevant clevis
and turning it clockwise to shoften the linkage or
counter - clockwise to lengthen it. Only when each
control surface has been centered mechanically in
this way should you begin adjusting the surface
movement (or throw)
Now confirm that the control surfaces are moving in
the correct direction. Use the servo reversing
switches on your transmitter to reverse the direc-
tion of a servo if necessary. The most popular
transmitter mode (with the throttle on the left, with
ailerons and elevator on the right) is shown here.
We have assumed throughout most of these instructions that
your J3 Piper cub is being powered by an electric motor and
Electronic Speed Control with BEC. Stage 21 applies only if
you are using glow power.
Step 21.1 Consult your radio manual for instructions about
hooking up your receiver battery, receiver and switch harness.

Step 22.4 Generally in the absence of specific instructions
from the radio manufacturer, it is recommended that the
receiver should be placed where it is least likely to have
impact during a crash. Keep the battery pack and other
heavy loose items ahead of the receiver.

CONFIRM RADIO
Carefully review how your Electronic Speed Control (ESC)
works. Most ESC's will not power up the motor until the
throttle has been reduced to zero. Avoid the prop in case
the motor suddenly stafts to turn.
Step 23.1 Consult your radio manual for instructions about
testing and operating your radio system.

BALANCING THE AIRCRAFT
Step 24.1 The CG for your J3 PIPER CUB is located at 2"
to 2-118" (50 - 55 mm) back from the leading edge of the
wing when the wing has been attached to the fuselage as
per illustration 25A.
Step 24.2 For the initial flight, the CG should be located at
2" (50mm) back from the leading edge of the wing when the
wing has been attached to the fuselage.
Step 24.3The CG is measured with the motor, battery and
all other components installed.
Step 24.4 Set up the CG as it will be when you fly it.
Step 24.5lt is very important to have the CG correct. Flying
your model with the CG too far back will likely lead to loss
Step 25.1 Once you have confirmed that the CG is correct,
you should do a thorough review of the entire model before
your first flight. Check everything twice! Every hook up,
every coupling, everything! Do it twice!!
Step 25.2 Before your first flight, have an experienced flyer
review your work. Do not fly your model until it has been
checked out by a third party who knows how to fly and how
to set up a model aircraft. Do not fly alone. Seek experi- , ,
enced help.
Step 25.3 Once you have completed your first flight, get in the
habit of checking your model over before and after each flight!

assembled your model and installed your radio, motor and
battery that the CG of your model is incorrect you must
bring the CG to the correct location by doing the following
BEFORE FLYING :
- Move the battery pack fore or aft
- Do not add weight to correct the CG. Move components
& especially your battery pack rather than add weight. Only
add weight as a measure of last resort.

Wing struts are very important. They must be correctly
installed and remain securely attached at all times during
flight. The wing will fail if flown without the struts.
To install the wing struts you need the struts themselves &
the four 2x10 [mm] screws supplied. Review the general
configuration of the struts shown in 26G.
Step 26.1 Locate the strut attachment point on the under-
side of each wing near the aileron servo. The locations
have been pre-marked at the factory. See 26A & 268
Step 26.2 Locate the strut attachment points on the fuse-
lage near the main gear. The locations have been pre-
marked at the factory. See 26C and 26D
Step 26.3 Mount the wing to fuselage.
Step 26.4 Attach the struts to the left and right wing so that
the thicker edge of the strut faces forward. See 26E
Step 26.5 Attach the struts to the fuselage. See 26F

BATTERY LOGATION
The battery location is behind the firewall. To install the bat-
tery, you must remove the battery hatch first then connect
the battery to your ESC.
Battery packs vary widely in size, shape and type. We rec-
ommend using a Lithium Polymer (LIPO) battery.
The battery can be moved fore or aft to adjust the CG to
the correct location. See 2BB
Once the CG is correct, the battery should be secured in
position with Velcro (supplied) or lightweight foam so that
the battery cannot move.
DO NOT FLY WITH A LOOSE BATTERY. tf the battery
moves it will shift the CG location and/or possibly unplug
itself causing loss of control.
