TIPS FROM THE PROS
Needle Nose Pliers
l Before installing the ducted fan assembly into the fuselage top, verify that the fan rotor spins in the correct direction. Connect the
ESC to the receiver and Li-Po battery, then apply low throttle. When applying throttle, the rotor should spin counter-clockwise when
viewed from the front. If the rotor spins in the wrong direction (clockwise), swap two of the three motor wires and check again.
l
The ducted fan assembly should only be tack-glued into the fuselage top, using two small dabs of 5 minute epoxy. This will hold the
ducted fan assembly rmly in place, yet allow easy removal if required.
l
The fuselage bottom should be tack-glued to the fuselage top in 3-4 places along each side. This will hold the fuselage bottom
securely in place, yet make it easier to remove it without damage, should service of the ducted fan assembly be necessary.
l
Excess epoxy that squeezes out of the glue joints can be cleaned off before it cures, using a paper towel soaked with rubbing
alcohol.
l
The servos should be installed with the servo horns toward the front of the fuselage.
l
When installing the wing panels, use plenty of 5 minute epoxy and coat all of the gluing surfaces thoroughly to ensure a strong
bond.
l
When installing the larger decals, we suggest drawing temporary guide marks to assist in positioning the decals.
l
Decals that go around curved surfaces may need several small slices cut in them to help prevent wrinkling or creasing.
l
If any air bubbles form underneath the decals, poke the air bubble with the tip of a pin to release the air, then rub the decals back
down.
l
Use a sharp pair of scissors to prevent tearing the colored area of the decals while cutting them out.
l
When installing the stabilators, make sure that the top of each is towards the top of the fuselage. When installed, notice that the
stabilators/tailerons are angled down. This is normal and by design.
l
For security, make sure all the ball-ends are completely screwed onto the threaded pushrod wires.
l
Make sure that both the stabilators/tailerons and their control arms are pushed rmly against the fuselage sides. Ensure that it is
not possible to move the stabilators/tailerons in or out.
l
Do not cut the receiver aerial shorter. Allow the excess to hang past the back of the fuselage. Cutting the receiver aerial shorter will
reduce the range of your radio control system considerably.

ASSEMBLING THE EF-16 EDF
WARNING It is very important to avoid the use of solvents or Cyanoacrylate (C/A) glue, which can damage foam. If any of these
chemicals comes into contact with the foam parts, the parts will be destroyed. Use only epoxy to assemble the parts.
STEP 1: INSTALLING THE ELEVON SERVOS
oPlug one 12" (305mm) servo extension into each of the two servos.
o Connect the radio control system, then centre the two servos, using the
elevator and aileron trim tabs on the transmitter.
o Install a servo horn onto each servo, making sure that both servo horns
are centered.
IMPORTANT Position the servo horns so that there is one right-hand
servo and one left-hand servo.
o Position one servo into one servo mounting pocket in the back of the
fuselage top, then cut away the foam to clear the servo lead.
IMPORTANT The servo horn should be towards the front of the
fuselage top.
o Install each of the two servos into the servo mounting pockets in the
fuselage top, using a small dab of 5 minute epoxy to hold them securely
in place.
IMPORTANT Again, the servos should be installed with the servo horns
towards the front of the fuselage top.
IMPORTANT Before centering the servos in the next procedure, make sure to enable the elevon mixing function in the transmitter.
For more information, please refer to the radio control system's operating guide.
STEP 2: INSTALLING THE DUCTED FAN ASSEMBLY
oInstall your choice of connectors onto the positive (red) and negative
(black) battery leads on the ESC. We suggest using 2mm gold-plated
connectors with heat-shrink tubing.
IMPORTANT Do not cut the battery leads shorter. They must be left long
to be able to reach into the middle of the cockpit.
Left-Hand Servo Right-Hand Servo
Fuselage Front

Page 6
o Cut a shallow notch in each side of the fuselage top just large enough
for the servo lead and/or servo plug to clear the sides of the ducted fan
assembly once it's installed.
oThe weight of the Li-Po battery will determine the exact mounting location
of the ducted fan assembly. If the Li-Po battery weighs 150 grams or
less, the ducted fan assembly should be installed in alignment with the
moulded mounting lip in the fuselage top. If the Li-Po battery weighs
151~160 grams, the ducted fan assembly should be mounted 30mm
(1-3/16") behind the moulded mounting lip in the fuselage top, and if the
Li-Po battery weighs 161~170 grams or more, the ducted fan assembly
should be mounted 1-1/2" (40mm) behind the moulded mounting lip in
the fuselage top.
PRO TIP Before installing the ducted fan assembly into the fuselage top, verify that the fan rotor spins in the correct direc-
tion. Connect the ESC to the receiver and Li-Po battery, then apply low throttle. When applying throttle, the rotor should spin
counter-clockwise when viewed from the front. If the rotor spins in the wrong direction (clockwise), swap two of the three motor
wires and check again.
Do not swap the positive and negative battery leads to change the direction that the rotor spins or you will damage
both the ESC and the Li-Po battery.
oTemporarily set the ducted fan assembly into the fuselage top.
q Apply one piece of hook and loop material to the back of the ESC and
one piece into the moulded ESC mounting pocket in the fuselage top.
o Test-t the ducted fan assembly into the fuselage top. When positioned
correctly, the motor wires should t into the moulded channel in the
fuselage top and the ducted fan shroud should t rmly against the radius
of the fuselage top. The front of the ducted fan assembly should be in
alignment with the moulded mounting lip in the fuselage top (depending on
the weight of your Li-Po battery as described in the procedure above).
q When satised with the t, glue the ducted fan assembly into the fuselage
top, using two small dabs of 5 minute epoxy, then x the ESC in place.
PRO TIP The ducted fan assembly should only be tack-glued into the fuselage top, using two small dabs of 5 minute epoxy. This
will hold the ducted fan assembly rmly in place, yet allow easy removal should you ever need to.
Up to

o Run the servo extension leads through the fuselage top and t them into
the notches that you cut to clear the sides of the ducted fan assembly.
qFeed the servo extension leads through the moulded hole and into the
cockpit, then use two strips of clear tape to secure the servo extension
leads to the fuselage top.
WARNING Don't allow the servo extension leads to hang loose.

Page 7
STEP 3: INSTALLING THE FUSELAGE BOTTOM
o Using 5 minute epoxy, glue the plastic intake support onto the front of
the fuselage bottom, making sure to push the intake support rmly into
place.
IMPORTANT If necessary, trim the bottom edges of the intake support
ush with the base of the fuselage bottom.
o Test-t the fuselage bottom onto the fuselage top. When positioned
properly, the sides of the fuselage bottom should t into the moulded
grooves in the fuselage top and the back of the fuselage bottom should
be even with the back of the fuselage top.
q When satised with the t and alignment, glue the fuselage bottom into place, using 3-4 dabs of 5 minute epoxy on each side.
o Double-check that the servo cutouts in the fuselage bottom do not interfere
with the servos. If necessary, enlarge the servo cutouts to allow clearance
for the servos.
IMPORTANT The servo cutouts in the fuselage bottom should not
interfere with the servo arms in any way.
PRO TIP The fuselage bottom should be tack-glued to the fuselage top in 3-4 places along each side. This will hold the
fuselage bottom securely in place, yet make it easier to remove it without damage, should service to the ducted fan assembly be
required.
oCut two 1-1/8" (29mm) wide strips from the reinforcement sheet.
PRO TIP To prevent any wrinkles or creases while applying the reinforcement strips in the next procedure, work slowly from the
front of the fuselage to the back, while pulling each of the reinforcement strips taut and rubbing them down into place.
PRO TIP Remove any excess epoxy that squeezes out of the joints, using a paper towel soaked with rubbing alcohol.
o Working with one reinforcement strip at a time, remove the paper backing
from the reinforcement strips and apply each of the two reinforcement
strips to the bottom of the fuselage, making sure to line up the inside edge
of each reinforcement strip with the centerline of the fuselage.
PRO TIP To make it easier to line up the reinforcement strips, draw a
temporary centerline mark at both the front and back of the fuselage.

Page 8
STEP 4: INSTALLING THE WING PANELS
o Glue one wing panel onto the fuselage, using a generous amount of 5
minute epoxy. The wing panel should be pushed rmly against the mating
surfaces of the fuselage and it should be aligned at both the leading edge
and the trailing edge. Remove any excess epoxy that squeezes out of
the glue joint, using a paper towel and rubbing alcohol and hold the wing
panel in place and aligned until the epoxy sets.
IMPORTANT When installing the wing panels in the next two procedures, make sure to use plenty of 5 minute epoxy, and coat
all of the gluing surfaces thoroughly to ensure a strong bond.
oRepeat the previous procedure to glue the second wing panel onto the
fuselage.
STEP 5: APPLYING THE DECALS
oVerify which is the top side of each stabilator/taileron before applying the
decals. Note that the pivot rod installed in each stabilator/taileron is not
centred - it is installed towards the bottom.
oCarefully cut out and apply the decals to the top and bottom of each of
the two stabilators/tailerons.
*The curved portion of the bottom decals will be applied to the underside
of the fuselage, after installing the stabilators/tailerons.
IMPORTANT The red and blue (only) decals are applied to the top of
the stabilators/tailerons. Ensure you make one right and one left.
o The decals are large, so work slowly and take care to line up the decals before removing the paper backing and adhering them
into place. It's easy to achieve excellent results. Here are some tips that may help:
l For the larger decals, we suggest drawing temporary guide marks to assist in positioning the decals.
l Peel away the backing material from one corner of each decal, then start in that corner and slowly apply each of the decals while
rubbing the decal down with your hand to smooth it out. Work slowly, pulling a small amount of the paper backing away at a time
and smoothing down the decal, until the entire decal is applied.
l Decals that go around curved surfaces may need several small slices cut in them to help prevent wrinkling or creasing.
l If any air bubbles form underneath the decals, poke the air bubble with the tip of a pin to release the air, then rub the decals back
down.
l Use a sharp pair of scissors to prevent tearing the colored area of the decals while you're cutting them out.
Top
Top Bottom

Page 9
oCarefully cut out and apply the decals to the right and left sides of the
n.
oCarefully cut out and apply the decals to both the bottom of the fuselage
and to the bottom of the wing panels.
IMPORTANT Any wrinkles or creases in the decals applied to the fuselage
bottom can be removed by making short cuts in the decal.
o Because the canopy frame is prepainted black, cut away the excess
portion of the decals that overlap onto the canopy frame. After applying
the decals, cut the decals along the front and back of the canopy, and
from over the canopy latch, to allow removal and installation of the canopy
itself.
PRO TIP Use two pieces of scrap black decal previously cut off, to cover
the open area between each side of the back of the canopy and the
decal.
STEP 6: INSTALLING THE STABILATORS
o Cut out the two plastic stabilator/taileron supports, making sure to cut
them out along the inside of the moulded lip.
qSand the edges of the supports smooth and straight.
o Test-t and glue one stabilator/taileron support to each half of the bottom
of the fuselage, using a thin layer of 5 minute epoxy. When positioned
properly, the notch on the inside edge of each support should line up with
the notch in the inside edge of the fuselage, and the outer edge of each
support should be even with the outside edge of the fuselage.
oCarefully cut out and apply the decals to both the top of the fuselage and
to the top of the wing panels.
IMPORTANT Again, any wrinkles or creases in the decals applied around
the canopy can be removed by making short cuts in the decals.

Page 10
oSlide the pivot rod of the right-side stabilator/taileron partially into the
pivot tube in the fuselage.
IMPORTANT Make sure that the top of the stabilator/taileron is towards
the top of the fuselage. When installed, notice that it is angled down. This
is normal and by design. If the stabilator/taileron is angled up, it's installed
onto the wrong side of the fuselage.
o While holding the stabilator/taileron tight against the fuselage side, and
with its trailing edge centred with the back edge of the fuselage, install
and tighten the machine screw in the top of the control arm, to secure it
and the stabilator/taileron in place.
IMPORTANT The position of the control arm is not important at this time.
The correct positioning of both the control arm and the stabilator/taileron
will be set when installing the control linkage.
oRepeat the previous procedures to install the second stabilator/taileron
and control arm assembly.
STEP 7: INSTALLING THE STABILATOR/TAILERON CONTROL LINKAGES
oApply one piece of perforated reinforcement board to each side of the
fuselage, between the fuselage top and the fuselage bottom. The centre
of each piece of reinforcement board should be 25mm (1") behind the
back edge of the servo cutout.
oThread one ball-end onto the end of each threaded pushrod wire.
IMPORTANT For security, make sure to thread the ball-end completely
onto the threaded pushrod wire.
oLine up the hole in the side of the stabilator/taileron control arm with the
end of the pivot rod.
qPush the stabilator/taileron up against the fuselage side (while holding
its control arm in place) to slide the stabilator/taileron pivot rod through
the hole in the side of the stabilator/taileron control arm.
IMPORTANT The stabilator/taileron control arm should be towards the
bottom of the fuselage.

Page 11
oSnap the ball-end onto the end of one stabilator/taileron control arm.
oPivot the stabilator/taileron so that its control arm is aligned straight up
and down when viewed from the side.
q With the control arm aligned straight up and down, and the with servo
horn centred, mark the pushrod wire where is crosses the outermost
hole in the servo arm.
o Connect the radio control system and Li-Po battery, then centre both servos using the Sub-Trim or Centre function on the transmitter.
o Remove the pushrod wire, then make a Z-Bend in the pushrod wire at
the mark you drew, using a pair of Z-Bend pliers.
qUse a pair of wire cutters to cut off the excess pushrod wire.
oInstall the Z-Bend into the outermost hole in the servo arm, then snap
the ball-end onto the end of the stabilator/taileron control arm.
q Verify that when the servo arm is centred, the stabilator/taileron control
arm is aligned straight up and down when viewed from the side. If it's not,
un-snap the ball-end, thread it in or out enough to achieve the correct
alignment, then snap it back onto the control arm.
oCarefully cut out and apply the remaining portion of the bottom
stabilator/taileron decals onto the bottom of the fuselage.
o Repeat the previous procedures to install the second stabilator/taileron linkage assembly and set the neutral point.
6mm (1/4")
o Loosen the machine screw in the top of the stabilator/taileron control arm,
then pivot the stabilator/taileron so that the centre of the leading edge is
positioned exactly 6mm (1/4") up from the bottom edge of the fuselage.
This is the neutral point of the stabilator/taileron. When satised
with the alignment, tighten the machine screw rmly.
IMPORTANT Make sure that both the stabilator/taileron and the control
arm are pushed rmly against the fuselage side. It should not be possible
to move the stabilator/taileron in or out.

Page 12
STEP 8: INSTALLING THE VERTICAL FIN
o Test-t and glue the n to the top of the fuselage, using a generous amount
of 5 minute epoxy.
IMPORTANT Before the epoxy cures, double-check that the vertical n
is aligned straight up and down when viewed from the front.
STEP 9: FINAL ASSEMBLY
o Test-t and glue the exhaust cone onto the back of the fuselage, using a
thin layer of 5 minute epoxy.
oApply one piece of perforated reinforcement board to the front and to the
back of the intake cutout in each side of the fuselage.
o Plug the servo and ESC leads into their correct slots in the receiver, then
mount the receiver to the cockpit oor, near the back of the cockpit, using
a small piece of hook and loop material.
o Remove the canopy by rst pulling the canopy latch forward, then by
pulling the back of the canopy up and off the fuselage.
o Drill a 2mm (5/64") diameter hole down through the cockpit oor (up
against the side of the cockpit), 102mm (4") behind the front of the
cockpit.
qUncoil the receiver aerial and feed it out through the hole.

Page 13
oSecure the receiver aerial along the entire length of the underside of
the fuselage, using several pieces of clear tape. Allow the extra receiver
aerial to hang past the back of the fuselage.
WARNING Do not cut the receiver aerial shorter. Allow the excess to hang past the back of the fuselage. If you cut the receiver
aerial shorter, the radio control system range will be greatly reduced.
o Mount the Li-Po battery to the cockpit oor, near the front of the cockpit,
using the remaining piece of hook and loop material.
IMPORTANT You may need to move the Li-Po battery either forward or
backward, depending on how the aircraft balances. The position shown is
a good starting point. Balancing will be done in the next section.
o Cut out the plastic Gatling gun, making sure to cut it out along the inside
of the moulded lip.
qSand the edges of the Gatling gun smooth and straight.
o Glue the Gatling gun onto the left side of the fuselage. When positioned
properly, the front of the Gatling gun should be even with the vertical
canopy frame and the bottom of the Gatling gun should be just above
the red portion of the red and blue decal.
o Secure the receiver aerial along the underside of the fuselage, next to
the fuselage bottom. Use pieces of clear tape to hold the aerial securely
in place.
IMPORTANT The receiver aerial must be prevented from accidentally
being sucked into the rotor.
oCarefully drill a 6mm (1/4") diameter hole through the front of the canopy
(drill through the clear plastic and through the foam), to allow air to enter
and cool the Li-Po battery. Warm air will exit through the moulded hole
in the back of the cockpit and into the air-intake duct.
IMPORTANT Make sure that the servo extension leads and ESC leads
are not completely blocking the moulded hole in the back of the cockpit.

Page 14
q The EF-16 EDF is supplied with an electronic speed
controller (ESC) that is very simple to set up. It is
connected as shown in the diagram at right.
q If using a Futaba transmitter, reverse the throttle channel.
If using a JR transmitter, leave the throttle channel in its normal position. If using a different
transmitter, refer to the user's guide provided with the radio control system. In all cases, leave the
throttle ATV (Adjustable Travel Volume)/End Points (EPA) set at 100%.
q With the throttle control stick at its LOW position, switch on the transmitter. Connect a fully-charged Li-Po battery. There is no
separate switch, so connecting the Li-Po battery will turn on the airborne radio components and begin the motor arming process.
Next, slowly move the throttle control stick to its HIGH position, then return it to the LOW position. You will hear an audible 'beep'
to conrm that the ESC is armed, and increasing the throttle now will cause the rotor to spin.
BALANCING, CONTROL THROWS AND ESC SETUP
STEP 1: BALANCING
BALANCE POINT (C/G):
l160mm to 190mm (6-1/4" to 7-1/2") in front of the trailing edge of each wing panel, measured at the wing panel glue joints.
IMPORTANT It is critical that the aircraft is balanced correctly. Incorrectly balancing the aircraft can cause it to lose control and
crash! Balance the aircraft right-side up.
o The EF-16 EDF must be correctly balanced before ying. The aircraft
should sit level or slightly nose down when supporting it on a balancer or
with your nger tips at the balance point. Move the Li-Po battery forward or
backward to balance the aircraft. Once satised that the aircraft balances
correctly, mark the mounting location of the Li-Po battery so that it can be
reinstalled in the same location each time after it is removed for charging.
1/4" (6mm)
STEP 3: SETTING UP THE ESC
STEP 2: CONTROL THROWS
lThe stabilators/tailerons function as both ailerons (to control roll) and elevators (to control pitch), and require the use of an onboard
electronic elevon mixer or a transmitter that features elevon mixing to work properly.
q Looking from the back of the aircraft, push the aileron control stick completely to the left. The trailing edge of the left stabilator/
taileron should move UP and the trailing edge of the right stabilator/taileron should move DOWN. Next, pull the elevator control
stick completely back. The trailing edge of both stabilators/tailerons should move UP. If they don't move as described, use the
aileron and/or elevator servo reversing function of the transmitter to change the direction that the stabilators//tailerons move.
THE CONTROL THROWS ARE MEASURED FROM THE LEADING EDGE OF THE STABILATORS/TAILERONS.
Elevator: 1" (25mm) Up and Down
Aileron: 1" (25mm) Up and Down
qRemember that the neutral point of the stabilators/tailerons is 6mm
(1/4") up from the bottom of the fuselage. With both the transmitter
aileron/elevator stick(s) plus trim tabs centred, the centre of the leading
edge of both stabilators should be 1/4" (6mm) up from the bottom of the
fuselage.
When measuring the control throws, measure from the neutral point.
l
Balancing the aircraft further back in the C/G range will make it more tail heavy and increase elevator control response and general
manoeuvrability. Balancing it further forward in the C/G range will make the aircraft more stable and smoother to y.

q While holding the transmitter in your other hand, push the throttle control stick forward to check that the motor powers up. Now,
pull the throttle control stick completely back.
q If there is any wind, turn to face it. While holding the throttle control stick completely forward (the rotor will spin very fast), hold the
aircraft just above shoulder level and rmly launch the aircraft straight ahead and level. Allow the aircraft to y straight and continue
to hold the throttle control stick completely forward so that the aircraft gains sufcient speed and climbs.
q The EF-16 EDF is a high-performance jet that yields its best performance when own smoothly and fast. The aircraft is perfect for
high-speed low passes down the runway and large, open aerobatics.
q After landing, unplug and remove the Li-Po battery from the aircraft and allow it to cool completely before recharging it for the next
ight.
FIXING MINOR CRASH DAMAGE
While you're ying the aircraft, there comes a time when you might crash. If the crash isn't too bad, most damage can be repaired
quickly and easily. If the damage is beyond repair, spare parts are available for purchase. If a foam part is going to break during a
crash it will usually break cleanly. To repair a clean break, follow the procedures below:
o Glue the broken parts together, using a thin layer of 5 minute epoxy or white glue, following the directions on the glue bottle. Hold
the parts together and in alignment until the glue fully cures.
o Apply a strip of clear tape over the seams to strengthen the joint even more.
WARNING It is very important not to use solvents or Cyanoacrylate (C/A) glue, which can damage foam. If any of these chemicals
comes into contact with the foam parts, the parts will be destroyed. Use only epoxy or white glue to repair damaged foam parts.
STEP 3: SETTING UP THE ESC (CONTINUED)
q Once the battery voltage level falls below the safe cut-off point (approximately 9 volts), power to the motor will be shut off, leaving
sufcient power for the radio during landing.
