The ElectriFly by Great Planes FlatOut Turmoil™ARF is an
excellent way to enjoy 3D aerobatics without the cost and
intensity of giant-scale, gasoline-powered models. After a
couple of hours on the workbench, your FlatOut Turmoil
ARF will be ready to tackle torque rolls, walls, harriers, high­alpha rolling circles and more! An excellent indoor or calm-

day outdoor performer, this airplane is a virtually unlimited
3D aerobat, but flying it involves only connecting the battery,
throttling up, and letting go!

Take care to build straight and true. Misaligned par ts will
hurt the air plane’s ability to perform the extreme aerobatics
it is designed for.

For the latest technical updates or manual corrections to the
FlatOut Turmoil ARF visit the Great Planes web site at
www.electrifly.com. Open the “Airplanes” link, then select
the FlatOut Turmoil 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.

Attention: The product you have purchased
is powered by a rechargeable battery. At the
end of its useful life, under various state and
local laws, it may be illegal to dispose of this

battery into the municipal waste system.
Check with your local solid waste officials for details in your
area for recycling options or proper disposal.

This product contains a chemical known to the state of
California to cause cancer and birth defects or other
reproductive harm.

1.Even though the FlatOut Turmoil ARF 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.

& OTHERS...FOLLOW THESE

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 written first. 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 FlatOut Turmoil ARF is
operated on the same frequency band as larger, “regular”
R/C models. If flying your FlatOut Turmoil ARF 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 f or
property damage or injur y). 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.

INTRODUCTION

TABLE OF CONTENTS

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 FlatOut Turmoil ARF requires
specialized radio gear. Refer to the

“DECISIONS YOU

MUST MAKE”

section 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.

We urge you to join the AMA (Academy of Model Aeronautics)
and a local R/C club.The AMA is the governing body of model
aviation and membership is required to fly at AMA clubs.Though
joining the AMA provides many benefits, one of the primary
reasons to join is liability protection. Coverage is not limited to
flying at contests or on the club field. It even applies to flying at
public demonstrations and air shows.Failure to comply with the
Safety Code (excerpts printed in the back of the manual) may
endanger insurance coverage. Additionally, training programs
and instructors are available at AMA club sites to help you get
started the right way .There are over 2,500 AMA chartered clubs
across the country. Contact the AMA at the address or toll-free
phone number below.

IMPORTANT!!! T w o of the most important things you can do
to preserve the radio controlled aircraft hobby are to avoid
flying near full-scale aircraft and avoid flying near or over
groups of people.

In the hands of a capable pilot the FlatOut Turmoil ARF is an
impressive 3D performer. But for the FlatOut Turmoil ARF 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 extensiv e testing,
following is the equipment we recommend so you can get
the most performance out of your FlatOut Tur moil ARF and
assemble it as shown in this instruction manual.

With a standard, four-channel radio, the FlatOut Turmoil
ARF is capable of all the basic 3D maneuvers. However,
some advanced pilots who are already familiar with handling
“flat foamies” may prefer to fly the FlatOut Turmoil ARF with
a computer radio capable of endpoint adjustments (for fine­tuning control throws), exponentials (for “softening” the
throws near the center of the travel), and various mixing
functions (such as rudder-to-elevator mixing for extended
knife-edge flight).

The FlatOut Turmoil ARF requires three,

sub-micro

servos
with a maximum weight of .3 oz [9g] 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 of 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 whatever servos will be used (not
all servos are compatible with all receivers–e v en 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.

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 FlatOut Turmoil ARF requires a 3-cell (11.1V), 350­700mAh lithium-polymer (LiPo) battery capable of providing
7A continuous discharge current. For long flight times and
good performance, we recommend the ElectriFly 3-cell, 3­Series 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 700mAh 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 2.3 oz.[65g].

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

High­Frequency 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) LiP o batteries such
as the ElectriFly PolyCharge 1-3-cell LiP o charger (GPMM3010)
must be used. If using another charger, it must be a LiPo
charger or have a LiPo charge mode. Never charge LiPo
batteries with chargers not intended for LiPo batteries or
chargers on NiMH or NiCd settings. Overcharging or explosion
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
listed above) 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 FlatOut Turmoil ARF is capable of 3D flight
with the included ElectriFly “stick-mount” motor and gearbox
combination. But for pilots who always insist on upgrading 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 few different types of adhesives that
the FlatOut Turmoil ARF could be assembled with, we have
had the best success with, and exclusively recommend
foam-safe CA such as 1 oz.Great Planes Foam Safe Thic k CA
(GPMR6072). Regular CA is not recommended as it will
aggressively attack the foam used in this model. In addition
to being foam-compatible, 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
FlatOut Turmoil ARF.

In addition to common household tools and hobby tools, this
is the “short list”of the most important items required to build
the FlatOut Turmoil ARF.

❏ 1.Cut the horizontal stabilizer free from the foam sheet

using a hobby knife with a

sharp

#11 blade.

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 clip hinges (C2) into the stabilizer, using
the 3 x 248mm [1/8" x 9-3/4”] elevator joiner tube as a guide.

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

❏ 4. Without removing the elevator halves from the foam

sheet, slide two hinge retainer rings (C3) onto the elevator
joiner tube. Align the rings with the cutout in the right
elevator half.There should be a 1.5mm [1/16"] gap between
the two rings. Secure both rings to the tube with a drop of
glue on the outside of the gap.Do not get any glue between
the rings.

❏ 5.Using the

Expert Tip

that follows, permanently join the

elevator halves by gluing in the elevator joiner tube.

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

B. Coat both sides of one hinge (C2) with foam-safe CA
where it contacts the sides of the hinge slot. Rotate the
hinge down into the slot. Be certain the top and bottom of
the hinge remain flush with the top and bottom of the
control surface you are hinging. IMPORTANT: Avoid
getting any CA on the tube or the arms of the clips. The
clips must rotate freely on the tube.

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

The clip hinge system provides a precise, free-moving
hinge. Always use this method when instructed to install
clip hinges.

HOW TO INSTALL CLIP HINGES

Assemble the Horizontal Stabilizer

BUILD THE AIRPLANE

7

❏ 6. Now the elevator halves may be cut from the sheet.

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

hinges to the joiner tube.

❏ 8. Inser t a Z-bend clevis (A1) into a clip hinge control

horn (C1).

❏ 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.

A. Using a sharp #11 hobby knife, remove any flashing
from the inside of the hole you are installing the Z-bend
clevis 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 larger.

B. Snap the Z-bend clevis into place.

HOW TO MAKE INSTALLING Z-BEND

CLEVISES EASIER

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 1-1/2" [38mm] pieces of removable
cellophane tape.Fold the last 1/4" [6mm] over to mak e a tab
for easy removal.

B. Lightly coat the leading edges of the elevators with
foam-safe CA–do not use an excessive amount. Hint: A
CA applicator tip is recommended to accurately control
the bead of glue.

C. Tape the tube to the leading edge of the elevators.
Weigh the assembly down on a flat surface to prevent
warping and allow the glue to harden without accelerator.

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

HOW T O GLUE THE TUBES TO

THE CONTROL SURFACES

8

❏ 1. Cut the wing and ailerons from the foam sheet.

❏ ❏ 2. Insert offset Z-bend clevises (A2) into opposing

sides of two clip hinge control horns (C1). Following the

Expert Tip

previously described, use the 3 x 863mm [1/8" x
34"] wing trailing edge tube as a guide to glue four hinges
and a control horn into each aileron. The control horns
should protrude from the bottom of the ailerons (black and
white side), and the offset Z-bend clevises should be on the
inboard sides of the horns. Remove the tube once the CA
has hardened.

❏ ❏ 3. Glue a control surface brace (E1) onto the roots

of the ailerons.

❏ 4. Slide four hinge retainer rings (C3) onto the wing

trailing edge tube. Position the rings so that they align with
the inner slots in the TE of the wing. Secure each retainer
with a drop of glue on the outside of the gap. Glue the
trailing edge tube to the TE of the wing.Be careful not to get
glue between the rings. Keep the 1.5mm [1/16"] spacing
between rings.

❏ 5. Glue the 3 x 785mm [1/8" x 31"] wing leading edge

tube to the LE of the wing.

❏ 1. Cut the upper and lower vertical fuselage halves

and the right and lefthorizontal fuselage halves free from
their foam sheets.If using the gearbox included with this kit,
or any other type of “stick-mount” gearbox, cut out all four
sections from the fuselage parts. If using a firewall­mounted, brushless outrunner motor, cut out only the
section from the lower vertical fuselage.

Assemble the Fuselage

Assemble the Wing

9

❏ 2. Glue the 5.5 x 146mm [7/32" x 5-3/4"] fuselage tube

doubler ov er the 3 x 726mm [1/8" x 28-1/2"] fuselage tube.

One end should be flush. From now on, this assembly will
be referred to as the fuselage tube.

❏ 3. Slide a fuselage joiner (E2), two fuselage servo

mounts (F3), and another fuselage joiner onto the fuselage

tube. With the tube doubler forward and the servo mounts
hanging down, the front servo mount should have its flat
surface on the left, and the rear servo mount should hav e its
flat surface on the right.

❏ 4.Position the servo mounts and fuselage joiners so that they

align with the precut slots in the upper vertical fuselage half.

❏ 5. Glue the fuselage tube to the upper vertical fuselage half.

❏ 6.Glue the left and right horizontal fuselage halves to the

fuselage tube. Make sure they are perpendicular to the
upper vertical fuselage.

❏ 7. Glue the stabilizer into position with the leading edge

of the stab butted against the rear fuselage joiner. Align the
notches in the stab with the fuselage tube.

❏ 8.Glue the wing into position with the leading edge of the

wing against the rear end of fuselage doubler tube.Align the
notches in the wing with the fuselage tube.

❏ 9. Glue the lower vertical fuselage half to the fuselage

tube. Make sure to keep it parallel with the upper half and
perpendicular to the horizontal fuselage.

10

❏ 10. Using the 3 x 160mm [1/8" x 6-1/4"] rudder post tube

as a guide, glue four clip hinges (C2) and a clip hinge control
horn (C1) to the rudder.The control horn should protrude from
the right side of the rudder.

❏ 11. Remove the rudder post tube from the rudder. Slide

two hinge retainer rings (C3) onto the bottom of the rudder
post. Align the rings with the slot in the TE of the fuselage.
Secure each ring with a drop of glue on the outside. Be
careful not to get glue between the rings.

❏ 12. Glue the rudder post tube to the TE of the

vertical fuselage.

❏ 13. Snap the rudder onto the r udder post.

❏ 14. Glue the 3 x 150mm [1/8" x 6"] strut brace tube into

the fuselage.

❏ 15. Locate eight rod supports (D2). In the following

steps note that four of the supports will be used for the main
landing gear and four of the supports will be used for the
wing struts at the trailing edge of the wing, but all of the
supports are exactly the same.

❏ 16.Installing them down through the top of the wing, glue

four rod supports (D2) into the slots in both sides of the
wing. Two of the supports are at the leading edge (for the
landing gear) and two are at the trailing edge (for the wing
struts). IMPORTANT: The holes in the supports must be
angled upward and outward (matching the angle of the
landing gear and the wing struts).

IMPORTANT!!! Before gluing in any of the supports, be
certain to read the steps all the way through so you will
understand how the supports go in.

11

❏ 17. Installing them from the left side, glue two more

supports into the slots in the fuselage. Note that these first
two supports should be positioned aft in the slots, and that
the holes in the supports should be angled downward and
outward (again, to accommodate the angles of the landing
gear and the struts).

❏ 18. Glue the remaining two supports into the left side of

the fuselage. Be certain that the holes are angled correctly.

❏ 19.Slide the 2 x 220mm [5/64" x 8-7/8"] landing gear legs

through the landing gear supports in the front of the wing and
fuselage. Ensure that the wing is parallel with the stab and
horizontal fuselage and perpendicular to the vertical fuselage.
Once satisfied with the alignment, secure the landing gear
legs with a drop of glue on both sides of each joint.

❏ 20. Slide the 2 x 85mm [5/64" x 3-3/8"] wing struts

through both sets of supports in the back of the wing and
fuselage. Make sure that the TE of the wing is aligned with
the LE, and secure the struts with a drop of glue on both
sides of each joint.

❏ 21.Glue the lower side-force generators (SFGs) onto

the bottom of the wing, using the precut slots as a guide.
These are the SFGs with the small notches in the middle.

❏ 22. Glue the upper SFGs onto the wing, using the

precut slots.Make sure the SFGs are perpendicular to the wing.

❏ 23. Slide the 2 x 230mm [5/64" x 9"] middle wing struts

through the slot at the center of the strut brace and into the slots
in the lower SFGs.Secure each end with a drop of glue.

12

❏ 24. Using an Easy-Touch bar sander with 220-grit

sandpaper, sand a bevel into the edges of the fuselage
diagonal reinforcements at a 45° angle toward the inside.
Glue the diagonal fuselage reinforcements into position
where shown. Be careful not to twist the fuselage as you
glue the parts down.

❏ 25. Snap the ailerons onto the wing TE.

❏ 1. Install a 2 x 17mm [5/64" x 21/32"] axle and axle

support (D1) onto each landing gear leg. Make sure that
the axles are perpendicular to the centerline.

❏ 2.Slide the wheels onto the axles, and secure them with a

wheel collar (D6).The flat side of the wheel collar should be

toward the wheel.Secure the wheel collar with a drop of glue
in the

teeth

opposite the wheels. Align the wheels with the
centerline and secure the axles and supports with a drop of
glue through the holes in both sides of the axle supports.

❏ 3. Make two wheel pants by gluing the inner and outer

wheel pant parts together. Be sure to make a right and a
left.Glue the inside of both wheel pants to the wheel collars.

❏ 4. Snap the tailwheel (D5) into the tailwheel bracket (D4).

Finish the Landing Gear

13

❏ 5. Slide the tailwheel bracket over the rudder and rudder

post. Glue the bracket to the rudder

only.Do not

glue the

bracket to the rudder post.

❏ 1.Remove the stock servo arms from all three of the servos

and temporarily connect the servos and ESC to your receiver.
Power up the system and center all three servos.

❏ 2.Refer to the

“Plastic T ree Parts”

listing on page 5 and
select the correct offset double-sided servo arm for the
aileron servo you will be using. There are three arms to
choose from:

Servo Arm A Hitec HS-55, Hitec HS-50, Futaba 3108M
Servo Arm B Futaba S3103, Airtronics 94091
Servo Arm C JR 241

❏ 3. Install two Z-bend clevises into the

underside

of the

offset double-sided servo arm.

❏ 4. Install the servo arm on the aileron servo in the

position shown. Both arms should be offset forward by the
same angle. Glue the aileron ser vo into a fuselage aileron
servo mount (F4).

❏ 5. With the output shaft forward, glue the aileron servo

into the cutout under the wing.

❏ 6.Glue the elevator servo into the front servo mount in the

right side of the fuselage.The output shaft should be forward.

❏ 7.Glue the rudder servo into the rear servo mount in the

left side of the fuselage.The output shaft should be forward.

❏ 8. Select two single-sided ser vo arms to fit the elevator

and rudder servos you are using. Insert a Z-bend clevis into
the outer hole of each arm. Mount the servo arms so that
they point straight down with the servos centered.

Radio Setup

❏ 9. Using an Easy-Touch bar sander with 220-grit

sandpaper, sharpen the ends of all the 1mm [3/64"] carbon
pushrods. This will make it much easier to install them
through the Z-bend clevises.

❏ 10. Slide a 1 x 120mm [3/64" x 4-3/4"] aileron pushrod

through the clevises in the aileron horns and servo arms.
Adjust the clevises until the ailerons are centered with the
servo centered. When you have the alignment correct,
secure the pushrod with a drop of glue where the pushrod
enters the clevis.Keep glue away from the end of the clevis
where it pivots in the arm or horn.

❏ 11. Slide two pushrod guides (E3) onto the 1 x 370mm

[3/64" x 14-1/2"] elevator pushrod and slide the pushrod
through the clevises on the elevator servo arm and control
horn. Adjust the clevises until the elevator is centered with
the servo centered. Secure the clevises with a drop of glue
on each clevis where the pushrod enters it.

❏ 12.Using the pushrod as a guide, drill two evenly-spaced

2.4mm [3/32"] holes through the fuselage for the pushrod
guides.Glue the base of each pushrod guide into the holes.

❏ 13. Install the 1 x 345mm [3/64" x 13-1/2"] rudder

pushrod the same way.

❏ 14. Connect all three servos to the receiver. Mount the

receiver to the bottom of the left horizontal fuselage with
double-sided foam tape.Make sure the receiver is far enough
forward so that it does not interfere with aileron motion.

❏ 15.Drill two 1.5mm [1/16"] holes through the fuselage where

shown.“Stitch” the receiver antenna through these holes.

15

If mounting the included stick-mounted motor and gearbox
or an after-market geared brushless system, follow the
instructions in this section. If mounting a firewall-mounted
motor system, proceed to

“Firewall-Mounted Motor

System”

on page 17.

❏ 1.The 10 x 10 x 27mm [25/64" x 25/64" x 1-1/16"] hardwood

motor mount block must be mounted in the correct
orientation.Identify the top, aft end of the block as shown in the
sketch so you will know how it is to be installed.

❏ 2. Without using any glue, slide the motor mount block

over the fuselage tube.Be certain the block is in the correct
position so there will be down and right thrust. Do not glue
the motor mount block onto the fuselage tube.

❏ 3. If using the included propeller, install the prop saver

onto the gearbox shaft with the large-diameter cone
forward.If using a GWS prop, install the prop saver with the
small-diameter cone forward. Tighten the screws, making
sure they engage the flat spots on the shaft.

❏ 5.Drill a 1.5mm [1/16"] pilot hole at an angle from the top

of the gearbox through the balsa block and carbon tubes.
Make sure the motor mount block does not rotate while
drilling. Secure the gearbox and block with a 2 x 8mm
[5/64" x 5/16"] wood screw.

❏ 6. If using an APC prop, insert the larger of the two

adapter rings (included in the propeller packaging) into the
rear of the propeller hub.

❏ 7. Secure the prop to the prop saver with one of the

included O-rings.

❏ 8. Connect your speed control to the motor and receiver.

Mount the speed control to the bottom of the right horizontal
fuselage with double-sided foam tape.Cut a small hole for the
ESC’s battery wire to cross to the right side of the fuselage.

Mount the Motor & Gearbox

❏ 9. Install the “hook” side of the included hook-and-loop

material to the left side of the fuselage where shown.This is
where you will mount the battery.

Use the following instructions if you are installing a fire wall­mounted motor system (usually brushless motors).

❏ 1. Glue the vertical fuselage doublers into position first,

then glue the horizontal fuselage doublers into position.

❏ 2. Use a 220-grit bar sander to lightly sand the front of

the fuselage even. Be careful not to change the built-in
thrust angles.

❏ 3. If installing an ElectriFly RimFire motor, glue the

included 3mm [1/8"] plywood firewallto the nose so that the
two pilot holes are centered on the horizontal fuselage, and
the top hole is centered on the fuselage tube. Note: If
installing another brand of outrunner motor, you will need to
cut your own firewall to match its mount pattern. The motor
and firewall should be mounted so that the thrust line is
offset 9mm [11/32"] below the center of the fuselage tube.

❏ 5.Mount the motor and propeller using the hardware and

instructions that came with your motor.

❏ 6. Install your ESC as instructed in step 8 of the

“Mount

the Motor & Gearbox”

section on page 16.

❏ 1. Attach the “loop” side of the included hook-and-loop

material to the battery.Mount the battery to the fuselage.

❏ 2. For safety, remove the propeller while performing

bench setup. Once you have finished setting up your
airplane, you can reinstall it.

Check the Control Directions

GET THE MODEL READY TO FLY

Firewall-Mounted Motor System

❏ 3. Lower the throttle stick all the way and turn on the

transmitter.Connect your battery to the ESC. If the ESC has
a BEC switch, turn it on.

❏ 4. Check all the control surfaces to see if they are

centered. Since you set the center points as you set up the
linkages, they should already be very close. Use the trims
on the transmitter to center the controls.

❏ 5. Make certain that the control surfaces and the motor

respond in the correct direction as shown in the diagram.To
operate the motor, you may have to “arm” your ESC.Follow
the instructions that came with your ESC to do this.If any of
the controls respond in the wrong direction, use the servo
reversing in the transmitter to reverse the servos connected
to those controls. Be certain the control surfaces have
remained centered. Adjust if necessary.

To simplify setup, the high-rate (3D) control throws for this
model are automatically set by the geometry of the included
hardware. We do recommend, however, that you perform a
quick check as described below to make sure the thro ws are
set up correctly.

Note: If your radio has the capability, low-rates will make it
easier to perform precision aerobatics. We recommend 40%
endpoints for all low-rate throws. If your radio does not have
low-rates, set up the plane using only the high-rate throws.

Additionally, you ma y w ant to use the e xponential function to
soften the control response around center.This is largely a
matter of personal taste, but helps many pilots balance the
extreme throws needed for 3D flying with the need to make
small corrections when in normal flight.

We recommend setting up your airplane according to the
table shown below

as a starting point

. However, setting up
models of this type is largely a matter of personal taste.We
encourage you to tune the throws to your taste as you get
more familiar with the aircraft.Many expert 3D fliers choose
to increase their high-rate travel by using higher endpoints.

To set the throws, use the Angle Templates on the back cover
page of this manual to verify that you are in the ballpark.

If you are not able to achieve these control throws, double­check your pushrod hookup and make sure any control
surfaces in question are operating smoothly. If you have a
computer radio, also make sure your endpoint adjustments
are properly set.

At this stage the model should be in ready-to-fly condition
with all of the systems in place including the motor, the
propeller, the battery, and the radio system.

More than any other factor, the C.G. (balance point) can
have the greatest effect on how a model flies, and may
determine whether or not your first flight will be
successful. If you value this model and wish to enjoy it for
many flights, DO NOT OVERLOOK THIS IMPORTANT
PROCEDURE. A model that is not proper ly balanced will
be unstable and possibly unflyable.

Balance the Model (C.G.)

Set the Control Throws

18

❏ 1.Use a felt-tip pen or 1/8" [3mm]-wide tape to accurately

mark the C.G. on the top of the wing on both sides of the
fuselage. The C.G. is located 3" [76mm] back from the
leading edge of the wing at the fuselage.

❏ 2. With all parts of the model installed, including the

battery (ready to fly), lift it upside-down on your fingertips at
the balance point you marked.

❏ 3. If the tail drops, the model is “tail heavy” and the

battery pack and/or receiver must be shifted forward or
weight must be added to the nose to balance. If the nose
drops, the model is “nose heavy” and the battery pack
and/or receiver must be shifted aft or weight must be added
to the tail to balance. If possible, relocate the battery pack
on the hook-and-loop strip to minimize or eliminate any
additional ballast required. If additional weight is required,
begin by placing incrementally increasing amounts of
weight on the bottom of the fuse until the model balances.
Once you have determined the amount of weight required,
it can be permanently attached.

❏ 4. IMPORTANT: If you found it necessary to add any

weight, recheck the C.G.after the weight has been installed.

❏ 1. With the wing level, lift the model by the engine

propeller shaft and the bottom of the fuse under the TE of
the fin. Do this several times.

❏ 2.If one wing always drops when you lift the model, it means

that side is heavy. Balance the airplane by adding weight to the
other wing tip.An airplane that has been laterally balanced

will track better in loops and other maneuvers.

No matter if you fly at an AMA sanctioned R/C club site or if
you fly somewhere on your own, you should always have
your name, address, telephone number and AMA number
on your model.It is required at all AMA R/C club flying sites
and AMA sanctioned flying events.Write this information on
the bottom of the wing with a fine felt-tip pen.

Follow the battery charging instructions that came with your
radio control system to charge the batteries.You should always
charge your transmitter batteries the night before you go flying,
and at other times as recommended by the radio manuf acturer .

Charge the flight battery using a charger designed for
Lithium-Polymer batteries. Charging with any other type of
charger is very dangerous, and may cause the batteries to
combust violently.

Ground check the operational range of your radio before the
first flight of the day. With the transmitter antenna collapsed
and the receiver and transmitter on, you should be ab le to walk
at least 15m [50 feet] away from the model and still have
control. Have an assistant stand by your model and, while you

Range Check

CAUTION: Unless the instructions that came with your

radio system state differently, the initial charge on new
transmitter batteries should be done for 15 hours using
the slow-charger that came with the radio system.This
will “condition” the batter ies so that the next charge may
be done using the fast-charger of your choice.If the initial
charge is done with a fast-charger, the batteries may not
reach their full capacity and you may be flying with
batteries that are only partially charged.

Charge the Batteries

Identify Y our Model

PREFLIGHT

Balance the Model Laterally

This is where your model should balance for the first
flights. Later, you may wish to experiment by shifting the
C.G. up to 1/2" [13mm] forward or 1/2" [13mm] back to
change the flying characteristics. Moving the C.G. forward
may improve the smoothness and stability, but the model
may then require more speed for tak eoff and mak e it more
difficult to slow for landing or 3D aerobatics. Moving the
C.G. aft makes the model more maneuverable, but could
also cause it to become too difficult to control.In any case,
start at the recommended balance point. As with the
throws, though, we encourage you to experiment with the
CG until the model flies to your taste.

work the controls, tell you what the control surfaces are doing.
Repeat this test with the motor running at various speeds
with an assistant holding the model, using hand signals to
show you what is happening. If the control surfaces do not
respond correctly, do not fly! Find and correct the problem
first. Look for loose servo connections or broken wires,
corroded wires on old servo connectors, poor solder joints in
your battery pack or a defective cell, or a damaged receiver
crystal from a previous crash.

Keep your f ace and body as w ell as all spectators a wa y from
the plane of rotation of the propeller whenever the battery
is connected.

Keep these items away from the prop: loose clothing, shir t
sleeves, ties, scarfs, long hair or loose objects such as
pencils or screwdrivers that may fall out of shirt or jacket
pockets into the prop.

your first flight.

❏ 10. Range check your radio when you get to the flying site.

During the last few moments of preparation your mind may
be elsewhere anticipating the excitement of the first flight.
Because of this, you may be more likely to overlook certain
checks and procedures that should be performed before the
model is flown.To help avoid this, a check list is provided to
make sure these important areas are not overlooked. Many
are covered in the instruction manual, so where appropriate,
refer to the manual for complete instructions. Be sure to
check the items off as they are completed.

MOTOR SAFETY PRECAUTIONS

The FlatOut Turmoil ARF is a great-flying model that flies
smoothly and predictably. The FlatOut Turmoil ARF does
not, however, possess the self-recovery characteristics of a
primary R/C trainer and should be flown only by experienced
R/C pilots.

For the first flight, it is a good idea to have an assistant
launch the airplane for you. This allows you to keep your
hands on the controls and immediately correct any trim
problems that are present.

Have your friend hold the FlatOut Turmoil ARF by the
canopy.Throttle up to full power, and giv e the plane a gentle ,
underhanded toss at about a 30° angle upward. Since the
FlatOut Turmoil ARF has a very high thrust-to-weight ratio,
the plane will accelerate to flying speed almost instantly.
Climb to a comfortable height and throttle back to a lower
power setting. This plane flies great at about half-throttle
when in standard forward flight.

Once you have the model trimmed out, the FlatOut Turmoil
ARF is very capable of ROG (rise-off-ground) takeoffs from
a smooth surface (parking lot, runway, gym floor, etc.). To
take off, start by advancing the throttle to about two-thirds,
making sure to correct any torque reactions with rudder.The
plane will build flying speed almost instantly due to its high
thrust-to-weight ratio. Once the tail comes up, gently apply
up elevator to break ground and climb out. Full throttle
takeoffs are necessary only for extremely short runways.

When flying a 3D aerobat like the FlatOut Turmoil ARF, there
are several things you should always keep in mind. First is
throttle management–this airplane has enough power to
climb straight up at full throttle, so level flight is more
comfortably achieved at about half-throttle. Avoid extremely
high-speed flight with the FlatOut Turmoil ARF–it is
designed for slow 3D aerobatics, and extended full-throttle
dives can result in wing flutter .While flutter won’t destroy the
airplane, it’s best to avoid it. Second, take it easy on the
control sticks–with 3D throws, even a small stick deflection
can result in a big response, so use small inputs (unless of
course you’re performing an aggressive maneuver).

Because this model is extremely lightweight, it slows rapidly
without power , and perf orming standard gliding landings can
be difficult. Instead, land the model under power, with a
rolling 3-point landing as the goal. To achieve this, perform
your landing approach with the model in the 3-point attitude
(nose up at such an angle that all three wheels are level).
Modulate your descent with the throttle, and use a quick
“blip”of power just before touchdown to slow the descent f or
a gentle landing.

Have a ball! But always stay in control and fly in a
safe manner.

GOOD LUCK AND GREAT FLYING!
