INTRODUCTION

Thank you for purchasing the Great Planes F-16 EDF (electric

ducted fan) ARF. With average speeds approaching 100mph,

your jet will have onlookers’ full attention as it cuts across

the horizon like a full-scale F-16 on patrol. Execute a Split-S
to come in for a low, high-speed pass across the fl ight line.

The EDF’s whine at full-throttle will echo off nearby buildings,

reminding you to keep your fi ngers tight on the sticks — this
bird is moving fast! Fortunately, the F-16 is a very stable fl ier
and doesn’t require expert fl ying skills to pilot, but it’s not a
beginner’s jet. The recommended battery provides just the
right amount of fl ight time for a plane of this size and speed…
and when you do bring it in for a landing, it will slow nicely
on approach and simply “settle in” on the grass when it’s
done fl ying.

For the latest technical updates or manual corrections to the
F-16 visit the Great Planes web site at www.greatplanes.com.

Open the “Airplanes” link, then select F-16 ARF. If there is new

technical information or changes to this model a “tech notice”
box will appear in the upper left corner of the page.

IMPORTANT!!! Two of the most important things you can

do to preserve the radio controlled aircraft hobby are to avoid
fl ying near full-scale aircraft and avoid fl ying near or over
groups of people.

SAFETY PRE CAUTION S

Protect Your Model, Yourself & Others…

Follow These Important Safety Precautions

1. Your F-16 should not be considered a toy, but rather a
sophisticated, working model that functions very much like a
full-size airplane. Because of its performance capabilities, the
F-16, if not assembled and operated correctly, could possibly
cause injury to yourself or spectators and damage to property.

2

2. You must assemble the model according to the instructions.

Do not alter or modify the model, as doing so may result in an

unsafe or unfl yable model. In a few cases the instructions may
differ slightly from the photos. In those instances the written
instructions should be considered as correct.

3. You must take time to build straight, true and strong.

4. You must use an R/C radio system that is in good condition,
a correctly sized engine, and other components as specifi ed
in this instruction manual. All components must be correctly
installed so that the model operates correctly on the ground
and in the air. You must check the operation of the model and

all components before every fl ight.

5. If you are not an experienced pilot or have not fl own this type
of model before, we recommend that you get the assistance
of an experienced pilot in your R/C club for your fi rst fl ights.

If you’re not a member of a club, your local hobby shop has

information about clubs in your area whose membership
includes experienced pilots.

6. While this kit has been fl ight tested to exceed normal use,
if the plane will be used for extremely high stress fl ying, such
as racing, or if an engine larger than one in the recommended
range is used, the modeler is responsible for taking steps to
reinforce the high stress points and/or substituting hardware
more suitable for the increased stress.

7. WARNING: The fuselage and tail cone adapter included in

this kit are made of fi berglass, the fi bers of which may cause
eye, skin and respiratory tract irritation. Never blow into a
part to remove fi berglass dust, as the dust will blow back into

your eyes. Always wear safety goggles, a particle mask and

rubber gloves when grinding, drilling and sanding fi berglass
parts. Vacuum the parts and the work area thoroughly after

working with fi berglass parts.

and the

❍ Great Planes ElectriFly 24-45-3790kV Ammo inrunner

brushless motor (GPMG5185).

These components drop right in with no modifi cation.

The recommended battery is the:

❍ Great Planes ElectriFly 14.8V (4S) 2200mAh 25C

LiPo (GPMP0521).

Under “normal” fl ying conditions (mostly full throttle), this
provides average fl ight times of approximately 4 minutes
with approximately one more minute of motor run time for
additional landing attempts.

❍ The Great Planes ElectriFly SS-35 35 Amp brushless

ESC (GPMM1830) is also recommended.

Note: A precision 1.5mm Allen wrench will be required for

tightening the set screws in the brass fan adapter. Do not
attempt to use an economy wrench. You may strip out the
wrench or set screws, making it impossible to securely tighten
or remove them for replacement. The 1.5mm MIP Thorp Hex
Driver (MIPR9007) is recommended.

Servos, Receiver

A small receiver and four micro servos in the 20 oz-in torque

range are required. Two 6" [152mm] servo extensions are also
required. Part numbers are provided below:

We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.

Remember: T ake your time and follo w the instructions to
end up with a well-built model that is straight and true.

DECISI ONS YOU MUST MAKE

This is a partial list of items required to fi nish the F-16 that may

require planning or decision making before starting assembly.

Order numbers are provided in parentheses.

Battery and ESC

The F-16 was designed for and comes equipped with the:

❍ Great Planes ElectriFly HyperFlow 56mm ducted fan

system (GPMG3910)

Suitable servo choices (in order of preference) for Futaba®
servos include:

❍ S3107 (standard micro – FUTM0025)

(shown in manual)

❍ S3156 (digital, metal gear, high-torque) (FUTM0656)
❍ S3153MG (digital, metal gear – FUTM0652)
❍ S3153 (digital – FUTM0653)
❍ S3117 (high-torque – FUTM0417)

❍ Hobbico® 6" Extension Futaba J (HCAM2000)

If you install a 4-channel receiver, a Y-harness is needed to
join the aileron servos together (FUTM4130). The aileron
servos can also be mixed together using a computerized
transmitter and 5+ channel receiver such as the Futaba
R617FS 7-Channel 2.4GHz FASST™ Receiver (FUTL7627).

ADD ITIONAL ITEMS R EQ UI RE D

Battery Chargers

● A LiPo-capable battery charger and a power source for the

battery charger are required. One recommended charger

is the Great Planes ElectriFly Triton

(GPMM3155). The Triton EQ can be powered either by an AC
or DC power source and features a built-in LiPo cell balancer.

● Another suitable LiPo battery charger is the Great Planes

PolyCharge4™ DC LiPo charger (GPMM3015). The
PolyCharge4 can charge up to four LiPo batteries at the
same time, but requires separate LiPo cell balancers, so
for each LiPo battery you wish to charge simultaneously
(up to 4), one Great Planes Equinox™ LiPo Cell Balancer
(GPMM3160) will be required. Additionally, the Equinox
comes with 2S and 3S charge adapters, so a 4S charge
adapter (GPMM3162) must also be purchased separately.
Finally, the PolyCharge4 does not have AC capability, so if
wall-charging from home is a priority, a separate A/C 12-Volt
power source must also be purchased. A suitable power
supply then for the PolyCharge4 is the Great Planes 12V

12A DC power supply (GPMP0901).

Assemble the Stand

The included plywood stand is used to support your F-16

during assembly and transport.

3. As shown in the HyperFlow manual, trim the three

❏

alignment guides from inside the fan housing. (Also as noted

in the HyperFlow manual, a rotary tool with a sanding drum
makes this easier.)

4. Trim any fl ashing from around the fan housing so the

❏

fi berglass cone adapter will fi t well.

Test-fi t, then glue together the plywood parts of the stand as

shown in the photos. The stand may be used as-is, or you
could add foam tape cut into 1/8" [3mm] wide strips that can be
adhered to the forward and aft saddles. The foam will adhere
best if you fi rst sand the edges of the stand, then seal with
medium CA before applying the foam.

Prepare the HyperFlow Fan Unit

1. Review steps 1 through 6 for Installing a Brushless

❏

Motor on pages 6 and 7 of the separate HyperFlow instruction

manual, but don’t perform any of the steps yet.

2. Enlarge the hole in the fan housing as shown. Once the

❏

fan unit and motor have been installed in the fuselage, this

P

FLAT

5. Press the brass fan rotor adapter onto the motor shaft—

❏

make sure one of the set screw holes in the adapter is aligned
with the fl at spot on the shaft and make certain the adapter
goes on all the way up to the threads. If you can’t get the
adapter to go all the way, use a hobby torch to heat the adapter
fi rst. Then, slide it into the shaft.

6

6. Add a small drop of threadlocker to the threads on the

❏

set screws for the adapter. Then, use a quality 1.5mm Allen

wrench to tighten set screws.

10. Mount the motor to the fan housing–you can use the

❏

3 x 5mm screws included with the Ammo motor (and a drop
of threadlocker on the threads). Any set of holes in the fan
housing that align with the holes in the motor may be used,
but we used the outer holes in the motor. Use care not to
overtighten the screws so much that you damage the plastic.

11. Glue the stator extension to the fan housing as shown

❏

in the HyperFlow manual. Make sure the little notches in the
stator fi t around the housing.

7. Test fi t only the fan rotor to the rotor adapter. If the head

❏

of the set screw opposite the fl at spot is protruding from the
adapter and making it diffi cult to install the fan rotor, cover the
front of the motor with a cloth or paper towel and use a metal

fi le to fi le down the screw so the fan will fi t properly.

8. Test mount the fan rotor to the adapter with the rotor

❏

cone, the 3mm Phillips screw and the 3mm washer that came

with the fan unit—the HyperFlow instructions specify using

a 3mm x 8mm screw, but the 3 x 5mm screw included with
the fan may be used.

Hint: For optimal performance it is desirable for the fan rotor
to turn as concentrically (“true”) as possible. T est fi t the rotor
in different orientations around the adapter, spinning it b y hand
each time. When y ou fi nd the orientation that is the truest, use
a hobby knife to lightly scratch a small “X” at the base of the
rotor where it aligns with the fl at spot on the motor. When you
mount the rotor later, do so in this orientation.

9. Remove the cone and rotor and set them aside.

❏

12. Lightly sand the edge of each blade on the stator

❏

extension to remove any fl ashing and to make sure they are
even with the fan housing.

13. Use medium-grit sandpaper to smooth the rough edges

❏

around the motor wire hole in the fi berglass tail cone adapter

so it won’t damage the motor wires.

7

14. Test fi t but do not glue the cone adapter to the rear of

ROTOR PULLER

1" [25mm]

3-1/2" [90mm]

1/4" [6mm]

❏

the fan housing. Note that the hole in the housing should be

180° from the side of the motor where the wires exit—this will

be the top of the unit. Once you have the housing and adapter

mated correctly, permanently glue the two together by adding

a few drops of thin CA to the seam around the outside. Also

apply a few drops of medium CA to each stator blade where

it contacts the inside of the adapter. Note: Apply the CA
sparingly and with care. Otherwise it will run all over the place.

15. Install the fan rotor onto the motor noting the orientation

❏

you marked earlier (for minimal run out)—be certain to use

a small drop of thread locking compound on the 3mm screw.

2. Follow all the precautions and run the motor at no more

❏

than 1/4 throttle as described by the “PREPARE TO RUN

THE FAN” instructions on the back cover of the HyperFlow

fan instructions. (If the motor is turning backwards switch any
two of the motor wires with each other.) Check for vibration
and/or unusual noises and do not proceed until resolving
any problems.

3. Continue with the rest of the break-in procedure until

❏

the system is fully broken-in. Or, if you’re satisfi ed with the
way the unit is performing, stop now and mount the unit in
the fuselage as described in the next section. Be certain to
complete the break-in procedure before fl ying your F-16 for
the fi rst time.

Surface Preparation

There are several steps in this manual that require you to

glue parts to the fi berglass fuselage. Anytime this is done,
the fi berglass should fi rst be cleaned with a cloth dampened
with denatured alcohol, sanded with 220 grit sandpaper, then
cleaned again with denatured alcohol. Doing this will ensure
a strong glue bond.

16. Cut the included heat shrink tubing into three equal

❏

lengths. Connect the motor lead extensions to the motor wires.

Slide the heat shrink pieces onto the motor lead extensions

and use a heat source (heat gun or lighter) to shrink the
tubing around the connections in order to prevent them from
becoming inadvertently disconnected.

17. Carefully slide the motor lead wires through the hole

❏

in the top of the cone adapter as shown.

Test Run the Motor/Fan Unit

1. You may perform either a brief test-run of the motor/fan

❏

unit, or do the complete break-in procedure as described on
the back cover of the HyperFlow instruction manual. In either
case prepare to run the motor by connecting the ESC to

your receiver and to the motor wires coming from the motor.
Reverse the throttle channel in your transmitter and turn on

the transmitter. Connect your motor battery to the ESC.

Install the Fan Unit

DESIGNER NOTE: The aft end of the tail cone is not

centered within the aft
end of the fuselage and
this can be seen by
looking at the plane
from the back side. This
is an intentional part of
the design to maximize
fl ight performance of
the aircraft.

It’s a good idea to test fi t the fan without glue so you can
make sure it fi ts properly. Once permanently installed, the
fan unit will not be possible to remove. However, the motor
may be removed by taking off the fan rotor, unscrewing the
