1. Slide the main gear into the slots in the fuselage until they lock into place.
Horizontal Tail Installation
We recommend watching the “Horizontal Tail
Installation” chapter/section of the assembly
video by scanning this QR code or using this URL:
www.horizonhobby.cc/AeroScoutS2assembly.
1. Slide the longer of the two included square carbon
ber tubes fully into the hole of either of the
horizontal stabilizers. The tube is a friction t and
does not require any adhesive.
IMPORTANT: The t will be tight.
TIP: Use a drop of dishwashing soap on the rod to help it slide though the
opening in the vertical stabilizer.
2. Insert the tube through the hole in the vertical tail of the fuselage as shown,
until the previously attached horizontal stabilizer is against the fuselage.
IMPORTANT: The decals on the horizontal stabilizers must face up when the
stabilizers are installed correctly.
3. Slide the opposite horizontal stabilizer over the other end of the tube. Press
the stabilizer halves together until they are both fully seated on the tube.
Use a credit card at the trailing edge to make sure there is a small (1mm)
gap between the stabilizers and the fuselage.
2. Insert the nose gear into the wheel collar as shown and tighten the screw
against the at in the gear wire using a PH#2 screwdriver.

video by scanning this QR code or using this URL:
www.horizonhobby.cc/AeroScoutS2assembly.
1. Slide the carbon ber wing joiner fully into a wing
panel as shown. Ensure the aileron servo lead exits
through the slot in the bottom of the wing.
2. Slide the opposite wing panel over the wing joiner until the root of the wing
panels are tight and the rear mounting hole is correctly aligned. Ensure
both aileron servo leads exit through the bottom of the wing and are not
pinched between the wing panels.
3. Connect the aileron servo leads to the y-harness installed in CH2 (channel
2) of the receiver.
4. Center the wing on the fuselage. Ensure the aileron leads are not pinched
between the wing and fuselage.
5. Attach the wing with the included 50mm screws. Do not overtighten the
wing screws, as it may damage the wing or the attachment points in the
fuselage.
IMPORTANT: The wing screws may be a tight t the rst few times they are
installed into the fuselage. Use a screwdriver if necessary until the fuselage
attachment points loosen enough for the screws to be installed by hand.
NOTICE: Do not overtighten the wing screws. Doing so will crush the foam of
the wing or damage the fuselage attachment points.

Transmitter Switches and LEDs
Button A = Trainer/Bind/Panic Button: This button is used to control the
Trainer, Bind and Panic Recovery Mode functions.
See the Flight Training section for information on using the transmitter as part
of a "buddy box" training system.
See the Binding section for information on re-binding your transmitter and
aircraft if necessary. The included transmitter comes bound to the receiver/
aircraft from the factory, therefore binding is not typically necessary.
See the Sensor Assisted Flight Envelope (SAFE) Technology section for informa-
tion about panic recovery mode.
Switch F = Hi/Lo Rate Switch: This switch supports high and low rate func-
tions on aileron, elevator and rudder channels.
We recommend using low rates when rst learning to y or for smooth and
more precise maneuvering, and high rates for more aggressive maneuvers and
aerobatics.
In the upper, or “HI” position, servo travel is 100% on these channels.
In the lower, or “LO,” position, servo travel decreases to 70%.
Switch B = Flight Mode Switch: This switch is used to select the SAFE ight
mode. See the Sensor Assisted Flight Envelope (SAFE) Technology section for
information about the various SAFE ight modes.
Switch H = Throttle Cut Switch: This switch activates throttle cut.
With throttle cut on (switch H,position 1), throttle input from the throttle stick is
deactivated. This safety feature ensures any accidental movement of the throttle
stick will not activate the motor while the ight battery is connected.
With throttle cut off (switch H, position 0), any position of the throttle stick above
the lowest setting will activate the aircraft motor.
NOTICE: Always ensure the throttle stick is at the lowest setting before
switching the throttle cut function off. Failure to do so will result in the motor
activating.
Switch D = Channel 7 Switch: This switch is not used for this aircraft.
RGB LED and Audible Indications:
Flashing with beeps: The transmitter is in bind mode, because the bind button
was held down while the transmitter was powered on. See the Binding section
for more information.
Pulsates with one low tone beep every 2 seconds: The transmitter battery
voltage has dropped below 4.7 volts. Replace the transmitter batteries immedi-
ately. If this happens while ying, land the aircraft as soon as possible.
Install the Transmitter Batteries
1. Remove the battery cover.
2. Install the included four AA batteries, noting proper polarity.
3. Reinstall the battery cover.
Low Battery Alarm
When the transmitter battery voltage drops below 4.7 volts, an alarm sounds
and the voltage LEDs ash. Replace the batteries immediately. If the alarm
sounds while ying, land your aircraft as soon as possible.
CAUTION: If using rechargeable batteries, charge only rechargeable
batteries. Charging non-rechargeable batteries may cause the
batteries to burst, resulting in injury to persons and/or damage to property.

1. Power on the transmitter.
2. Turn on the THROTTLE CUT switch (motor power inactive).
3. Lift at the rear of the battery hatch to remove it from the fuselage.
4. Attach a piece of adhesive-back loop material to the bottom of the battery.
5. Place the battery, loop material down, on the battery tray. The placement of
the battery can be adjusted forward or backward to help balance the aircraft.
6. When the battery is properly placed, secure it with the hook and loop.
7. Connect the IC3 battery connector to the ESC, noting proper polarity.
CAUTION: Connecting the battery to the ESC with reversed polarity
will cause damage to the ESC, the battery or both. Damage caused by
incorrectly connecting the battery is not covered under warranty.
CAUTION: Always keep hands away from the propeller. When armed,
the motor will turn the propeller in response to any throttle
movement.
8. The control surfaces will cycle as the SAFE system initializes. Initialization
is complete when the surfaces stop moving.
CAUTION: Always disconnect the Li-Po ight battery from the aircraft
when not ying to avoid over-discharging the battery. Batteries
discharged to a voltage lower than the lowest approved voltage may become
damaged, resulting in loss of performance and potential re when batteries
are charged.
Flight Battery Voltage Indicator
The included DXS transmitter is equipped with a ight battery voltage indicator
feature that works with compatible Smart technology-equipped receivers, ight
controllers and telemetry-capable ESCs. This Smart technology feature gives a
visual representation of the approximate ight battery voltage/power remaining
via the four LED indicators on the transmitter.
• When the battery is fully charged, all four LEDs glow solid.
• When the throttle is increased, the voltage of the battery drops,
causing the LEDs to indicate less voltage and useable capacity of
the battery remains, via fewer LEDs glowing solid or ashing.
• When the throttle is decreased, the load on the battery decreases and the
voltage of the battery increases, indicated by more LEDs glowing solid or
ashing. Over time less of the useable capacity of the battery remains and
less power is available, indicated by fewer LEDs glowing solid or ashing.
• When the last LED begins to ash, the ight battery low voltage alarm
on the transmitter sounds before the low voltage cutoff function is
triggered in the aircraft ESC (see the Flying section for a description
of the low voltage cutoff function). The ight battery low voltage
alarm sounds for 25 seconds. If the throttle is lowered and the ight
battery voltage recovers because enough useable capacity remains
in the ight battery, the alarm will stop before 25 seconds. In either
case, land the aircraft as soon as practical after the alarm sounds.
To reset the ight battery low voltage warning:
1. After landing, disconnect the ight battery from the aircraft for at least
15 seconds, or until the ight battery voltage indicator LEDs on the DXS
transmitter go out.
2. Connect a fully charged battery to the aircraft. The ight battery voltage
indicator resets prior to the next ight.

Center of Gravity (CG)
We recommend watching the “Center of
Gravity” chapter/section of the assembly video
by scanning this QR code or using this URL:
www.horizonhobby.cc/AeroScoutS2assembly.
CAUTION: Never y the aircraft without ensuring the center of gravity
is within the acceptable range. Failure to properly balance the aircraft
can result in loss of control and possible damage. Crash damage is not
covered under warranty.
After installing the ight battery and before powering on the ESC, verify the
center of gravity is correct. The CG should fall within 60–75mm from the
leading edge of the wing, measured at the wing root. However, for the best
ight characteristics, the suggested CG location is 75mm behind the leading
edge of the wing, measured at the wing root as shown.
The ight battery and canopy must be installed to balance the aircraft correctly.
Hold the aircraft upright, with both index ngertips at the suggested CG
location, on either side of the fuselage.
• If the aircraft stays level, the aircraft is balanced on the suggested CG
location.
• If the nose tips down, move the ight battery rearward until the aircraft
balances level on the suggested CG location.
• If the nose tips up, move the ight battery forward until the aircraft
balances level on the suggested CG location.
When ying in beginner mode with the correct CG, the aircraft should climb
gradually at full power, and y level at 50-60% power with no added elevator
input.
• If the aircraft CG is too far forward (nose heavy), up elevator is required to
y level at 50-60% power.
• If the aircraft CG is too far aft (tail heavy), down elevator is required to y
level.
Adjust the battery position as needed.
NOTE: All ight trimming should be done in Experienced ight mode, not
Beginner or Intermediate ight modes.

Before attempting to y this aircraft for the rst time, we strongly recommend
using the RealFlight Trainer Edition RC Flight Simulator (RFL1205, sold
separately) and a Spektrum WS2000 Wireless Simulator Dongle (SPMWS2000,
sold separately) along with the DXS transmitter included with the RTF Basic
version to learn and practice the basics of ying. Featuring six popular Horizon
Hobby trainer aircraft — including the AeroScout S 2 1.1m aircraft — and
built-in Virtual Flight Instructor lessons, new pilots can learn to y successfully
by practicing on a PC at home or on a laptop just about anywhere else!
We also encourage you to connect with experienced RC pilots in your area
through hobby shops or at designated ying elds. And for those located in
the United States, we recommend joining a national organization such as the
Academy of Model Aeronautics (AMA). The AMA can provide information on
local clubs, instructors and established ying sites in your area in addition to
insurance coverage. Visit www.modelaircraft.org for more information.
Control Direction Test
Before Your First Flight
WARNING: Do not perform this or any other equipment test without
turning on throttle cut. Serious injury or property damage could result
from the motor starting inadvertently.
If the control surfaces do not respond as shown, DO NOT FLY. Refer to the
Troubleshooting Guide for more information. If you need more assistance,
contact the appropriate Horizon Hobby Product Support department.
1. Power on the transmitter.
2. Turn on throttle cut (switch H, position 1).
3. Set the ight mode switch to Experienced Mode (switch B, position 2).
IMPORTANT: Do NOT check the controls in the Beginner or Intermediate Modes
(switch B, position 0 or 1).
4. Place the model on level ground away from obstacles.
5. Power on the aircraft, and wait for it to fully initialize.
6. Move the sticks on the transmitter as shown in the table and observe the
control surfaces on the aircraft. Ensure the aircraft control surfaces respond
as shown and return to neutral when the control input is released.
7. Check for any binding in the control surfaces.
8. With the aircraft on a smooth surface, roll the aircraft forward by hand.
Push the rudder trim button on the transmitter left or right until the aircraft
tracks straight.
TIP: The transmitter emits a faint beep with each click of the trim buttons in
either direction. Holding the button in either direction quickly adjusts the trim
several steps until the button is released or until the trim reaches the end of its
travel. If the trim button does not beep when clicked, the trim is at the far end
of its travel. Center trim is indicated by a slightly louder beep.
Centering the Control Surfaces
After checking for correct control surface movement and nose wheel
alignment, release the transmitter sticks. Check each of the control surfaces to
make sure they are centered.
TIP: The nosewheel is centered with the electronic rudder trim. The rudder is
then centered manually.
For any surface that is not centered:
1. Slide the retaining sleeve off the clevis.
2. Gently pry the clevis open.
3. Slide the clevis pin out of the control horn.
4. Rotate the clevis on the pushrod to lengthen or shorten the length of the
pushrod to adjust the center position of the surface.
5. When the correct position is achieved, slide the clevis pin back into the
correct control horn hole.
6. Close the clevis, capturing the control horn between the sides.
7. Slide the retaining sleeve over the clevis to keep the clevis from opening.

WARNING: While holding the aircraft during the range test, always
keep body parts and loose items away from the motor. Failure to do
so could cause personal injury.
Before each ying session, and especially with a new model, you should
perform a range check.
The included Spektrum DXS transmitter incorporates a range check mode to
reduce the output power of the transmitter so you don't have to be as far away
from the receiver to check the range. Follow the directions below to enter
range check mode for the DXS transmitter:
1. With the throttle stick set to the lowest setting, power on the transmitter for
at least 5 seconds.
2. With the help of an assistant to hold the aircraft, connect the aircraft battery
to the ESC connector. Keep the aircraft immobile for 5seconds.
3. Face the model, holding the transmitter in your normal ying position.
4. Press and hold the bind button (button A) and toggle the HI/LO rate switch
(switch F) up and down twice. The transmitter RGB LED will ash and the
alarm will sound, indicating the system is in range check mode. Do not
release the bind button until the range check is complete.
IMPORTANT: You must hold the bind button through the entire range check
process. Releasing the button will exit range check mode.
5. With the model rmly restrained on the ground, stand approximately 30
paces away from the model.
TIP: In some aircraft, when the model is placed on the ground, the antenna(s)
can be within inches of the ground. Close proximity of the antenna(s) to the
ground can reduce the effectiveness of the range check. If you experience
issues during the range check, restrain the model on a non-conductive stand
or table up to 2ft (60cm) above the ground, then range check the system again.
6. Move the transmitter rudder, elevator, aileron and throttle controls to ensure
they operate smoothly at approximately 30 paces. If control issues exist,
do not attempt to y. Refer to the Warranty and Service Contact Information
table at the end of the this manual to contact Horizon Hobby product
support.
7. When the range check is successfully completed, release the bind button to
exit range check mode.
CAUTION: Due to reduced output power of the transmitter, NEVER
attempt to y while the transmitter is in range check mode. Loss of
control will occur.

Choose a Flying Field
Consult local laws and ordinances before choosing a location to y your aircraft.
In order to have the most success and to protect your property and aircraft,
it is very important to select a place to y that is very open. We recommend
consulting your local hobby shop for information on local ying elds and clubs.
For customers in the United States, visit the Academy of Model Aeronautics at
www.modelaircraft.org for more information on ying clubs.
Remember, this aircraft can reach signicant speeds when ying and will cover
ground very quickly. Plan on ying in an area that gives you more space than
you think you need, especially during the initial ights.
The chosen ying site should:
• Have a minimum of 1300 feet (400m) of clear space in all directions.
• Be free of trees, buildings, cars, power lines or anything that could entangle
your aircraft or interfere with your line of sight.
• Be clear of people and pets.

IMPORTANT: Even though SAFE technology is a very helpful tool, the aircraft
still needs to be own manually. If incorrect input is given at lower altitudes
or at slower speeds, the aircraft can crash. Study these control inputs and
the aircraft response to each carefully before attempting your rst ight.
For rst ights, set the SAFE®ight mode switch to Beginner Mode (switch B,
position0). For smooth control of your aircraft, always make small corrections.
All directions are described as if you were sitting in the aircraft.
Throttle, Faster or Slower
• Push the throttle stick forward to make the aircraft go faster and climb.
• Pull the throttle stick back to slow down and descend.
Elevator Up and Down
• Pull the elevator stick back to make the nose of the aircraft go up.
• Push the elevator stick forward to make the nose of the aircraft go down.
Aileron Right and Left
• Move the aileron stick right to make the aircraft roll or bank right.
• Move the aileron stick left to make the aircraft roll or bank left.
TIP: Always picture yourself in the aircraft when determining which way to
bank the aircraft wings.
• When the aircraft is ying away from you, banking the aircraft right or left
appears normal.
• When ying toward you, the aircraft will appear to bank the opposite
direction to the control input given. This will become more instinctual with
experience.
TIP: When ying toward yourself, if one of the wings drops, move the aileron
stick toward the low wing to level the aircraft.
Rudder Right and Left
• Push the rudder stick right to yaw the aircraft nose to the right.
• Push the rudder stick left to yaw the aircraft nose to the left.
The rudder stick is also used to steer the aircraft left and right while taxiing on
the ground.
TIP: Similar to aileron control, picture yourself in the aircraft to determine
which direction to point the nose whether you are ying away from yourself or
toward yourself.

At any time during a ight you can switch between Beginner, Intermediate
and Experiencedight modes or use panic recovery to get your aircraft to a
safe ying attitude. Change between ight modes by changing the ight mode
switch position.
Beginner Mode (switch B, position 0)
Flight envelope limits: Pitch
(nose up and down) and Roll
(wing tips up and down) angles
are limited to help you keep the
aircraft airborne.
• Self-leveling: when the
pitch and roll controls
are returned to neutral,
the aircraft returns to level ight.
• Stability assisted takeoff and landing.
• Throttle based climb and descent.
Intermediate Mode (switch B, position 1)
Less ight envelope limits:
Pitch (nose up and down) and Roll
(wing tips up and down) angles are
still limited to help you keep the
aircraft airborne, but you will have
more freedom in pitch and roll.
• NO self-leveling: self-leveling
is only active in Beginner Mode.
Experienced Mode (switch B, position 2)
NO ight envelope limits: There
are no pitch or roll limits, and no
self-leveling, so you have complete
control! You can even y inverted
(upside down) and perform
aerobatic maneuvers including
loops, rolls and more.
Panic Recovery
This function is intended to provide you with the condence to continue to
improve your ight skills. If you become disoriented or the aircraft is in an
unknown or uncomfortable attitude in any ight mode:
1. Press the Bind/Panic button (button A) on the transmitter and release the
control sticks. The aircraft will immediately pull out of a dive and roll wings
upright and level.
IMPORTANT: The aircraft will recover to a safer attitude even if sticks are held
while holding the Panic button. However, release the control sticks for the
quickest recovery.
2. Release the Panic button and continue your ight.
CAUTION: The panic recovery function will not avoid obstacles in the
aircraft ight path. Sufcient altitude is required for the aircraft to
return to straight and level ight if the aircraft is upside down when the
panic function is applied.

In Flight
Let the aircraft climb at full throttle, into the wind, until the aircraft gets about
100 feet (30m) above the ground, then decrease the throttle to half (50%).
Make small and gentle stick movements to see how the aircraft responds.
Flying with the nose pointed toward you is one of the hardest things to do
when learning to y. Practice ying in large circles high off the ground.
If you lose orientation of the aircraft, press and hold the PANIC button and the
aircraft will return to level ight.
As you are ying:
• Fly at a high enough altitude to give yourself time to react to what the
aircraft is doing.
• Make small and gentle stick movements to see how the aircraft responds.
• Practice ying in large circles, high off the ground. Flying with the nose
pointed toward you is one of the hardest skills to master when learning to
y. Flying in circles will give you experience viewing the aircraft from all
angles.
• If you lose orientation of the aircraft, press and hold the Panic Recovery
button and release the sticks. The aircraft will return to level ight. Release
the button to continue your ight.
NOTICE: If a crash is imminent, activate throttle cut or quickly lower the
throttle and throttle trim. Failure to do so could result in greater damage to
the airframe, as well as damage to the ESC and motor.

Flying Video
This aircraft is relatively easy to y and helps you apply beginner skills to
ying; however, we recommend you get help from a qualied ight instructor
for your rst radio controlled ights. Some model ying clubs provide ight
training at their ying elds. Find a nearby ying club through your local
hobby shop. In the U.S., visit the Academy of Model Aeronautics at www.
modelaircraft.org for more information on clubs and ight instruction.
Takeoff
Set the ight mode switch to Beginner mode (switch B, position 0) for your rst
ights. Set a ight timer for 5 minutes. Adjust the ight timer for later ights,
depending on your ight battery choice.
Position the aircraft on the runway, facing into the wind. Slowly advance the
throttle to start the takeoff roll into the wind. Small rudder inputs may be
required to keep the aircraft headed straight. As the throttle is advanced and
sufcient speed is attained the aircraft will begin a slow climb out.
Hand Launch
Once the aircraft is ready for ight, use the following steps.
1. Grip the aircraft under the fuselage, behind the main gear.
2. Slowly advance the throttle to 100%.
3. Throw the aircraft slightly nose up and directly into the wind.

Low Voltage Cutoff (LVC)
Low Voltage Cutoff is a function built into the electronic speed control to
protect the battery from over-discharge. When the ight battery charge is low,
LVC limits power supplied to the motor so the ight controls receive sufcient
energy to safely land the aircraft.
When LVC engages, the aircraft will slow and the motor will begin to pulse.
When the motor power decreases, land the aircraft immediately and charge the
ight battery.
NOTICE: Repeated ying to the low voltage cutoff will damage the battery.
Landing
1. Reduce the throttle to around 50% to slow the airspeed.
2. Fly the aircraft downwind past the end of the runway.
3. Turn the aircraft into the wind and line the aircraft up with the runway
center line.
4. Gradually decrease the throttle further to begin descending towards the
runway, keeping the wings level during approach. Try to have the aircraft at
approximately 10 feet (3 meters) altitude as it passes over the threshold of
the runway.
5. As the aircraft passes over the threshold of the runway decrease the
throttle.
6. Just as the aircraft is about to touch down, gently pull back on the elevator
to raise the nose, or are, for a gentle landing on the main landing gear. The
goal is to be at a low enough speed so the aircraft will not climb when the
landing are is started.
TIP: If the aircraft bounces back into the air, either increase the throttle slightly
and ease the aircraft gently back down to the runway, or increase the throttle
to full power, climb out and go around to begin the landing process again.
7. Continue using the rudder stick to steer the aircraft straight down the
runway, allowing the aircraft to roll to a stop.
NOTICE: If a crash is imminent, activate throttle cut or quickly lower the
throttle and throttle trim. Failure to do so could result in greater damage to
the airframe, as well as damage to the ESC and motor.
IMPORTANT: When nished ying, never keep the aircraft in the sun. Do not
store the aircraft in a hot, enclosed area such as a car. Doing so can damage
the foam.

Adjusting Trim in Flight
If your aircraft does not y straight and level at half throttle with the sticks
at neutral, y into the wind and adjust the trim sliders as indicated in the
transmitter table until the aircraft maintains a reasonably straight and level
ight path.
• Trimming is best done in calm wind conditions.
• The SAFE ight mode switch must be set to Experienced mode
(switch B, position2) before adjusting the trims.
After the aircraft is trimmed in ight, land the aircraft and proceed to the
Manually Adjusting Trim section to re-center the servos and set the trim
mechanically.
The included DXS transmitter features electronic trim buttons. The transmitter
emits a faint beep with each click of the trim buttons in either direction.
Holding the button in either direction quickly adjusts the trim several steps
until the button is released or until the trim reaches the end of its travel. If the
trim button does not beep when clicked, the trim is at the far end of its travel.
Center trim is indicated by a slightly louder beep.
TIP: Trim the aircraft at sufcient altitude of about 100' (30 meters). Having
an experienced ight instructor trim your aircraft during the rst ight is
recommended.

Manually Adjusting Trim
WARNING: Do not perform any maintenance with the propeller
installed on the aircraft. Serious injury or property damage could
result from the motor starting inadvertently.
The SAFE ight mode switch should be set to Experienced mode (position2)
before manually adjusting the trim settings.
The aircraft should be kept still while perfoming manual adjustment of trim.
With the trim settings from the trim ight still set in the transmitter, take note of
the positions of each of the control surfaces, one at a time.
1. Remove the canopy.
2. Using #2 Phillips screwdriver, loosen the screw on top of the easy
connector located on the servo arm.
3. Carefully move the linkage forward or rearward, depending upon which
direction control surface requires trim adjustment.

Trimming the Aircraft
Transmitter and Receiver Binding
Binding is the process of programming the aircraft receiver with the identica-
tion code of the transmitter so the receiver will only connect to that specic
transmitter.
The included transmitter was bound to the aircraft at the factory. If the aircraft
does not respond to transmitter control inputs when the batteries in the aircraft
and transmitter are fully charged, the aircraft receiver and transmitter may need
to be re-bound.
To re-bind the transmitter and receiver:
1. Power OFF the transmitter
2. Set the throttle stick to the low position and all other controls to neutral.*
Ensure the aircraft is immobile.
IMPORTANT: The throttle will not arm if the transmitter’s throttle control is not
put at the lowest position.
3. Connect the ight battery to the ESC. The receiver will begin to ash
orange.
4. An extension is installed in the receiver bind port. You may bind through the
battery hatch at the front of the aircraft without having to remove the wing
assembly. Simply insert the bind plug in the open end of the extension to
enter bind mode.
5. Press and hold the bind button (button A) on the transmitter while powering
ON the transmitter.
6. When the receiver binds to the transmitter, the receiver LED will glow solid,
and the aircraft will begin the initialization process, indicated by the control
surfaces cycling.
7. Remove the bind plug from the bind port extension and store in a safe
place. Once properly bound, the receiver and transmitter will retain their
bind for future ights.
If you encounter problems, refer to the troubleshooting guide. If necessary,
contact the appropriate Horizon Hobby product support ofce.
* Failsafe
The receiver stores the position of the transmitter throttle control at the time
of binding as the failsafe position. If the receiver should ever lose communi-
cation with the transmitter, the failsafe function will activate. Failsafe moves
the throttle channel to its preset failsafe position (low throttle) that was stored
during binding. All other control channels move to put the aircraft in a slowly
descending circle until radio link is re-established.
IMPORTANT: When nished ying, never keep the aircraft in the sun. Do not
store the aircraft in a hot, enclosed area such as a car. Doing so can damage
the foam.
LiPo battery tips:
• Disconnect and remove the Li-Po battery from the aircraft after use to
prevent trickle discharge.
• Charge your Li-Po battery to about half capacity for long term storage.
• During storage, make sure the battery charge does not fall below 3V per
cell.
• Always read and follow all safety warnings and guidelines included with
your LiPo batteries.
Post Flight
Disconnect the ight battery from the ESC.
Power OFF the transmitter.
Remove the ight battery from the aircraft.
Recharge the ight battery.
Repair or replace all damaged parts.
Store the ight battery apart from the aircraft and monitor the battery
charge.
Make note of the ight conditions and ight plan results, planning for future
ights.

Flight Training
* Some transmitters with older versions of Spektrum Airware software may use different terminology to describe the Student and Instructor functions.
To the new pilot:
This aircraft is easy to y and helps you apply beginner skills to ying;
however, we recommend you get help from a qualied ight instructor for your
rst radio controlled ights. Some model ying clubs provide ight training at
their ying elds. Find a nearby ying club through your local hobby shop. In
the U.S., visit the Academy of Model Aeronautics at www.modelaircraft.org for
more information on clubs and ight instruction.
To the ight instructor:
Feel free to experiment with the SAFE technology before instructing your
student on this aircraft. The progressive switch positions in the SAFE
technology are intended for a new pilot to learn with minimal instructor
assistance. We recommend using Flight Mode Switch Position 1 to instruct a
new pilot. Switch positions 0 and 2 may stabilize the aircraft more or less than
desired for instruction purposes.
DXS Wireless Trainer Feature
Your DXS transmitter may be connected wirelessly to another transmitter
through the SRXL2 DSMX Remote Receiver (SPM9747, sold separately).
The DXS transmitter is ideal as the instructor transmitter as it is compatible
with all Spektrum transmitters when using this feature. Servo reversing and
trims must be the same on both transmitters.
This “buddy box” approach has helped many new pilots get the feel for
aircraft control with the close assistance of a ight instructor. Connecting two
transmitters enables your ight instructor to hold the master transmitter while
you hold the slave transmitter. While you learn to y, the instructor holds the
trainer switch to give you control of the aircraft. If you need help, the ight
instructor can release the switch to take control.
IMPORTANT: If a transmitter other than the included DXS is used as the
instructor or student transmitter, refer to Buddy Box Setup section below.
Remote Receiver Installation
1. Open the battery door.
2. Connect the remote receiver cable to the wireless trainer port.
3. Install the remote receiver in the cavity behind the battery door with double

To use a Spektrum transmitter other than the included DXS, use the setup table
which corresponds to your transmitter series, DX, NX or iX series, to program
the transmitter.
When using the recommended setup, the transmitter switch layout is as follows:
• Switch B Selects the Flight mode; Beginner (position 0),
Intermediate (position 1), Experienced (position 2)
• Button I controls the Panic mode (depressed activates Panic mode)
• Switch F controls the aileron dual rates
• Switch C controls the elevator dual rates
• Switch G controls the rudder dual rates.
• Switch H controls the throttle cut.
IMPORTANT: After completing the transmitter setup or making any changes to
the transmitter setup, the transmitter and receiver must be re-bound to save
the desired failsafe positions.
Dual Rates
Make the initial ights in low rate, changing to high rate elevator for landing.
NOTICE: To ensure AS3X technology functions properly, do not lower rate
values below 50%. If less control deection is desired, manually adjust the
position of the pushrods on the servo arm
NOTICE: If oscillation occurs at high speed, refer to the Troubleshooting
Guide for more information.
Exponential
After rst ights, adjust the exponential settings in the transmitter to ne tune
the responsiveness of the aircraft around neutral to your preference.
