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.
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
information about panic recovery mode.
Switch F = Hi/Lo Rate Switch: This switch supports high and low rate
functions 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
immediately. If this happens while ying, land the aircraft as soon as possible.

Install the Flight Battery
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.

Battery Selection
• We recommend the Spektrum 2200mAh 11.1v 3s 30C Li-Po (SPMX223S30).
• If using another battery, the battery must be at least 2200mAh capacity.
• The battery should be approximately the same capacity, dimensions and
weight as the Spektrum Li-Po battery to t in the fuselage without changing
the center of gravity a large amount.
1. Lower the throttle stick to the lowest setting and center the throttle trim.
Power on the transmitter, then wait 5 seconds.
2. Apply a strip of hook tape to the bottom of the battery near the end opposite
the battery wires.
3. Turn the latch and open the battery hatch.
4. Install the ight battery as shown. See the Center of Gravity (CG)
instructions for more information.
5. Make sure the ight battery is secured using the hook and loop strap.
6. Connect the battery to the ESC. Close the hatch. Turn the aircraft over and
place it on its wheels. Keep the aircraft immobile and away from wind for
5 seconds.
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 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 recommended voltage may
become damaged, resulting in loss of performance and potential re when
batteries are charged.
CAUTION: Always keep hands away from the propeller. When armed,
the motor will turn the propeller in response to any throttle movement.

Center of Gravity (CG)
Assembly Video
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/CarbonCubS2assembly.
62-68 mm back
from the leading
edge at the wing
root
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 62–68mm from the
leading edge of the wing.
The ight battery must be installed to balance the aircraft correctly.
Hold the aircraft 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 in Intermediate and Experienced modes, 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.
In Beginner mode the aircraft is not affected. The SAFE system controls the
aircraft attitude.
Adjust the battery position as needed.
