The FlatOuts Extra 300S ARF is an excellent way to enjoy 3-D
aerobatics without the cost and headaches of giant-scale
gasoline-powered models. After a couple of hours on the
workbench, your Extra 300S ARF will be ready to tackle torque
rolls, walls, harriers, high-alpha rolling circles and more! An
excellent indoor or calm-day outdoor performer, this airplane is
a virtually unlimited 3-D aerobat, but flying it involves only
connecting the battery, throttling up, and letting go!

Take care to build straight and true.Misaligned parts will hurt
the airplane’s ability to perform the extreme aerobatics it is
designed for.

IMPORTANT SAFETY PRECAUTIONS

A NOTE ABOUT METRIC DIMENSIONS

Since the parts of this airplane have been designed with
metric dimensions, the metric size (in millimeters) of the parts
is listed first in the text.For convenience, we have listed close
approximations of these sizes in the English system (inches),
but be aware that these conversions are only approximate.

CAUTION: Be aware that the FlatOuts Extra 300S ARF is
operated on the same frequency band as larger, “regular”
R/C models.If flying your Extra within five miles of an R/C
site, there is a real possibility that you could be operating
your model on the same frequency (channel) as another
R/C pilot. If this happens a crash will result–with the
person flying the more expensive model suffering the
greater loss (and having greater potential for property
damage or injury). The best thing to do is to join an R/C
club and fly at the site where frequency control measures
will be in effect.If you insist on flying elsewhere always be

aware of your proximity to R/C flying sites.

1.Even though the FlatOuts Extra 300S is small, lightweight
and flies slowly, if it is not assembled and operated correctly
it could possibly cause injury to yourself or spectators and
damage property.

2. Build the plane according to the instructions. Do not alter
or modify the model, as doing so may result in an unsafe or
unflyable model.

3.Use an R/C radio system and components that are in first­class condition. The FlatOuts Extra 300S requires
specialized radio gear. Refer to “

DECISIONS YOU MUST

MAKE”

to get an accurate description of the specialized

gear required.

4.You must properly install all R/C and other components so
that the model operates correctly on the ground and in the air .

5. You must test the operation of the model before every
flight to insure that all equipment is operating, and that the
model has remained structurally sound. Be sure to check
connectors often and replace them if they show signs of
wear or fatigue.

Remember:Take your time and follow directions to end
up with a well-built model that is straight and true.

If you’re not already an AMA (Academy of Model
Aeronautics) member, we highly recommend that you join.
In addition to providing liability protection while operating
under the AMA Safety Code, the AMA is the governing body
of model aeronautics in the United States and fights for your
rights as member of the modeling community.You must also
be an AMA member to fly at R/C clubs chartered by the
AMA–most of which are.Contact the AMA at the address or

In the hands of a capable pilot the FlatOuts Extra 300S is an
impressive 3-D performer. But for the Extra 300S to perform
to its full potential, it must be properly equipped with all the
right gear (servos, batteries, receiver, speed control).There
may be more than one type and brand of radio equipment
that can be used, but based on extensive testing, following
is the equipment we recommend so you can get the most
performance out of your Extra 300S and assemble it as
shown in this instruction manual.

With a standard, four-channel radio, the FlatOuts Extra 300S is
capable of all the basic 3-D maneuvers. However, some
advanced pilots who are already familiar with handling “flat
foamies”may prefer to fly the Extra 300S with a computer radio
capable of endpoint adjustments (for fine-tuning control throws),
exponentials (for “softening” the throws near the center of the
travel), and v arious mixing functions (such as rudder-to-elev ator
mixing for extended knife-edge flight).

The FlatOuts Extra 300S requires three

sub-micro

servos with a
maximum weight of 9g [.3 oz] each and a minimum torque rating
of 15 oz-in. Futaba®S-3108M (micro connector) servos
(FUTM0700) are ideal because they meet the torque and weight
requirements and have a micro connector that is compatible with
the Futaba

Ultra Micro

receiver. Although there may be other
servos that will physically fit in the model, those outside the
recommended weight and torque specifications will adversely
affect flight performance and are not recommended. Note:
During assembly when it’s time to mount the servos, you will be
instructed to glue them in. Do not be alarmed as this is a
common practice with this type of lightweight, high-performance
model. Should servo removal ever be necessary for repair,
replacement or transfer to another model, this can be done by
prying them out with a hobby knife or a small screwdriver.

The lightest four-channel receiver is recommended and must be
compatible with whatev er servos will be used (not all servos are
compatible with all receivers–even servos and receivers within
the same brand). The Futaba R-124F

Ultra Micro

receiver is
recommended and is compatible with the 3108M servos
recommended.Note: Futaba receivers are sold on high and low
bands and come without crystals. Following are the order
numbers for the R-124F receiver and compatible crystals:

Low Band High Band

(Channels 11-35)

(Channels 36-60)

R124F Receiver FUTL0438 FUTL0439
Crystal FUTL62** FUTL63**

**Replace the “**” in the order number for the crystals with
the preferred channel number. For example, if you want to
fly on channel 33, order a low band receiver and crystal
number FUTL6233.

DECISIONS YOU MUST MAKE

AMA

Note: We, as the kit manufacturer, provide you with a top

quality kit and great instructions, but ultimately the quality and
flyability of your finished 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.

The FlatOuts Extra 300S requires a 3-cell (11.1V), 350­700mAh lithium-polymer (Li-Po) battery capable of providing
7A continuous discharge current. For long flight times and
good performance, we recommend the ElectriFly 3-cell,

3-Series

640mAh battery pack (GPMP0805). For minimum

weight, at the expense of some flight time, the ElectriFly 3-cell,

3-Series

350mAh battery pack (GPMP0801) works well.Note:
The ElectriFly 720mAh battery is not recommended for this
model as it is not capable of delivering the current required by
this system. For optimum performance battery weight should
not exceed 65g [2.3 oz.].

An electronic speed control capable of handling a minimum of
7A continuous current is required. Additionally, the speed
control should be as light as possible. The ElectriFly C-10
Micro High-Frequency ESC w/BEC (GPMM2010) is suitable .If
upgrading to the optional brushless motor system
recommended (below), a speed control intended for brushless
motors (a brushless speed control) capable of at least 8A
continuous current such as the ElectriFly BL-8 (GPMM2070)
must be used. NEVER use speed controllers intended for

brushed motors on brushless motors (and vice-versa).

A charger capable of charging 3-cell (11.1V) Li-Po batteries
such as the ElectriFly PolyCharge 1-3-cell Li-Po charger
(GPMM3010) must be used. If using another charger, it must
be a Li-Po charger or ha ve a Li-P o charge mode .Never charge
Li-Po batteries with chargers not intended for Li-Po batteries or
chargers on NiMH or NiCd settings.Overcharging or e xplosion
may result.In addition to the PolyCharge , the ElectriFly Triton

™

(GPMM3150) or Accu-Cycle Elite™(HCAP0280) are also
suitable chargers.

Many chargers (including the Triton and Accu-Cycle Elite) do
not include charging leads, but rather have banana jacks to
plug the leads into.If this is the case with your charger, you will
need to purchase a charge lead to match your battery.For the
recommended 640mAh pack, the correct lead is GPMM3105.

Rest assured, the FlatOuts Extra 300S is capable of 3-D flight
with the included ElectriFly “stick-mount” motor and gearbox
combination.But for pilots who always insist on upgr ading and
don’t mind spending a little extra money, the ElectriFly Rimfire
22M-1000 brushless motor (GPMG4500) will provide
increased power and flight time while simultaneously reducing
weight. Don’t forget, if upgrading to a brushless motor, a

“brushless”speed controller such as the ElectriFly BL-8 8-Amp
ESC (GPMM2070) must be used. This kit also includes the
firewall and instructions for mounting a brushless motor.

A 10 x 3.5 propeller is included in this kit, and this propeller
offers the best performance with the included motor system.
If you are upgrading to the RimFire brushless motor , a 9 x 3.5
propeller is recommended.

Though there may be a fe w diff erent types of adhesiv es that the
FlatOuts Extra 300S could be assembled with, we hav e had the
best success with, and exclusively recommend foam-safe CA.

1 oz. Great Planes Foam Safe CA Medium (GPMR6069)
2 oz. Great Planes Foam Safe CA Medium (GPMR6070)
1 oz. Great Planes Foam Safe CA Thick (GPMR6072)
2 oz. Great Planes Foam Safe CA Thick (GPMR6073)

Regular CA is not recommended as it will aggressively attack
the foam used in this model. In addition to being foam­compatible, foam-safe CA is also suitable for gluing together all
of the rest of the materials (balsa, carbon) included in this kit.No
other adhesive is required to build the FlatOuts Extra 300S ARF.

In addition to common household tools and hobby tools, this
is the “short list”of the most important items required to build
the FlatOuts Extra 300S.

KIT INSPECTION

❏ 1. Cut the stabilizer free from the foam sheet with a

sharp

#11 hobby knife.

DO NOT

cut the elevator halves

free at this time.

❏ 2. Following the

Expert Tip

below, use foam-safe CA and
accelerator to glue six C2clip hinges into the stabilizer, using the
3 x 272mm [1/8" x 10-11/16"] elevator joiner tube as a guide.

HOW TO INSTALL CLIP HINGES

The clip-hinge system provides a precise, free-moving
hinge.Install all of the clip hinges on this model following the
instructions below.

A. Snap all of the hinges onto the carbon rod. Align the
hinges with the slots.

B. Coat both sides of one hinge with foam-safe CA where it
contacts the sides of the hinge slot.Rotate the hinge down into

the slot. Be cer tain the top and bottom of the hinge remain
flush with the top and bottom of the control surface you are
hinging.IMPORTANT :Avoid getting an y CA on the tube or the
arms of the clips.The clips must rotate freely on the tube.

C. One at a time, coat the sides of each hinge and glue them
into the slots.

❏ 3. Remove the elevator joiner tube from the hinges.

❏ 4. Without removing the elevator halves from the foam

sheet, slide two C3 hinge retainer rings onto the elevator
joiner tube.Align the rings with the cutout in the left elevator

half.There should be a 1.5mm [1/16"] gap between the two
rings. Secure each ring with a drop of glue on the outside of
the gap.Avoid getting glue between the rings.

❏ 5. Following the

Expert Tip

below, permanently join the

elevator halves by gluing in the elevator joiner tube.

HOW T O GLUE THE TUBES TO THE CONTROL SURFACES
NOTE: You may want to protect your work surface from

excess glue. We recommend Great Planes Plan Protector
(GPMR6167) for this purpose.

A. Cut several 38mm [1-1/2"] pieces of tape. Fold the last

6.5mm [1/4"] over to make a tab for easy removal.
B. Coat the edge of the foam with foam-saf e CA–do not use

an excessive amount of glue. Hint: A CA applicator tip is
recommended to accurately control the bead of glue.

C. Use the tape pieces to hold the tube against the foam
edge. Weigh the parts down on a flat surface to prevent
warping and allow the glue to cure without accelerator.

D. Once the glue has cured, remove the tape.

❏ 6. Cut the elevator halves free of the sheet.

❏ 7. Join the elevators to the stab by snapping the clip

hinges to the joiner tube.

❏ 8. Insert an A1 Z-bend clevis into a C1 clip-hinge

control horn.

HOW TO MAKE INSTALLING Z-BEND CLEVISES EASIER

A. Using a sharp #11 hobby knife, remov e any flashing from

the inside of the hole you are installing the Z-bend into. Do
this by rotating the blade in the hole while applying gentle
pressure. Be careful not to remove too much material–your
goal here is to remove small ridges of flashing, not to make
the hole bigger.

B. Snap the Z-bend clevis into place.

❏ 9. Clip the control horn onto the joiner tube aligned with

the precut slot.

❏ 10.Coat the gluing area on the control horn with glue and

rotate it down into the precut slot.
