Flashing with beeps: The transmitter is in bind mode. The bind button is held while the transmitter is powered on (see
the Binding section).
Pulsates with one low tone beep every 2 seconds: 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.
Flight Battery Voltage Indicator
The included DXS transmitter includes a ight battery voltage indicator feature.
The Smart ight battery voltage indicator will rise and lower depending on throttle/power
usage. When throttle is increased, voltage drops, causing the LEDs to indicate lower power
(e.g., fewer LEDs solid or ashing.) When the throttle is lowered to idle/off, the LEDs recover
(e.g., more LEDs solid or ashing).
The Smart ight battery low voltage alarm sounds when the ESC is close to reaching low
voltage cutoff. The alarm will sound for 25 seconds. If the throttle is lowered to allow voltage
recovery, the alarm will stop early. Land the aircraft when the alarm sounds.
After landing, reset the Smart ight battery low voltage warning by either powering cycling
the DXS transmitter, or disconnecting the battery from the aircraft for more than 15 seconds or until the voltage indicator
LEDs go out.
Connect a fully charged battery to the aircraft, which will ensure the Smart Battery low voltage warning resets prior to the
next ight.

1. Lower the throttle stick to the lowest position.
2. Power ON the transmitter.
3. Center all trims. For the included Spektrum DXs
transmitter (RTF only), the trims are centered when
you hear a higher pitched beep while pressing the trim
button. Move the trim in both directions until you hear
the high-pitched beep.
4. Attach the hook material to the helicopter frame and
the loop material to the ight battery.
5. Install the ight battery on the helicopter frame.
Secure the ight battery with the hook and loop strap.
NOTICE: If the ight battery hook and loop strap is
pulled too tight, it may result in a vibration or the tail ro-
tor may drift to the right during ight. If you experience
either of these issues, loosen the strap slightly and y
again.
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.
If you experience issues during initialization, refer to the
Troubleshooting Guide at the back of the manual.
CAUTION: Always disconnect the Li-Po
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.
WARNING: Always activate throttle hold and
wait until the main rotor blades and tail rotor
stop spinning before handling the model.
The throttle trim on the transmitter must remain at the
center position. Raising the throttle trim above center
may cause the main and tail motors to begin spinning.

Transmitter and Receiver Binding
Low Voltage Cuto (LVC)
The ESC will continuously lower power to the motor until
complete shutdown when the battery reaches 9V under
load. This helps prevent over-discharge of the Li-Po
battery. Land immediately when the ESC activates LVC.
Continuing to y after LVC can damage the battery, cause
a crash or both. Crash damage and batteries damaged
due to over-discharge are not covered under warranty.
Repeatedly ying the helicopter until LVC activates will dam-
age the helicopter battery.
Disconnect and remove the Li-Po battery from the aircraft
after use to prevent trickle discharge. During storage, make
sure the battery charge does not fall below 3V per cell.
SMART Throttle (BNF Only)
The new line of Spektrum ESCs feature a telemetry func-
tion called SMART Throttle. SMART Throttle technology
combines the throttle signal with telemetry data from the
ESC on one normal three wire servo connector.
SMART Throttle ESCs can send current, voltage, ESC temp,
and mAh consumed. They can also pass along battery
data from compatible Spektrum SMART batteries. SMART
Throttle telemetry data shows up on your transmitter like
any other telemetry sensor.
For SMART Throttle to function you must have a SMART
Throttle ESC paired with a SMART Throttle telemetry
receiver, and a Spektrum DSMX transmitter with telemetry.
Only certain Spektrum products include SMART technology
compatibility, check your receiver and ESC manual for
more information. An update for your transmitter may be
required for SMART features.
(See www.spektrumrc.com to register and update your
transmitter.)
To activate SMART Telemetry:
1. Keep the vehicle powered on after binding the trans-
mitter to the receiver
2. Scroll to the Telemetry screen
3. Scroll to Settings
4. Select Auto Cong
To activate Speed infomation using SMART Telemetry:
5. After doing the initial SMART telemetry conguration
keep the vehicle powered on
6. Scroll to the Telemetry screen
7. Scroll to SMART ESC and double select
8. Scroll down to NEXT
9. Enter the values for the magnetic pole count of the
motor and the gear ratio (motor and gear ratio infor-
mation can be found in the manual for your vehicle)
When the radio is on and connected to a receiver sending
SMART Data, the SMART Logo will appear under the battery
logo on the home page and a signal bar will appear in the
top left corner of the screen. Scrolling down, past the servo
monitor, the SMART screens will appear. Select either ESC,
battery, or both for display to suit your preference.

Revolutionary SAFE®(Sensor Assisted Flight Envelope)
technology uses an innovative combination of multi-axis
sensors and software that allows model aircraft to know
its position relative to the horizon. This spatial awareness
is utilized to create a controlled ight envelope the aircraft
can use to maintain a safe region of bank and pitch angles
so you can y more safely. Far beyond stability, this level of
protection offers multiple modes so the pilot can choose to
develop his or her skills with a greater degree of security
and ight control that always feels crisp and responsive.
SAFE technology delivers:
• Flight envelope protection you can enable at the ip of
a switch.
• Multiple modes let you adapt SAFE technology to your
skill level instantly.
Best of all, sophisticated SAFE technology doesn’t require
any work to enjoy. Every aircraft with SAFE installed is
ready to use and optimized to offer the best possible ight
experience.

Technology
Flight Mode and Rate Selection
In Stability Mode the bank angle is limited. When the
cyclic stick is released the model will return to level.
In Intermediate Mode the bank angle is not limited. When
the cyclic stick is released the model will not return to
level. This mode is great for learning forward ight and
basic aerobatics such as stall turns and loops.
In Agility Mode the bank angle is not limited. When the
cyclic stick is released the model will not return to level.
This mode is great for 3D aerobatics such as stationary
ips and tic tocs.
Change rates in any mode by moving the two-position
dual rate switch.
• Low rate reduces the control rates, providing an easier
to y model. Beginners should use low rate for initial
ights.
• High rate provides full control and should be used by
intermediate and experience pilots.
Panic Recovery
If you get into distress while ying in any mode, activate
the panic function and move the control sticks to their
neutral position. SAFE technology will immediately return
the aircraft to an upright level attitude, if the aircraft is at
a sufcient height with no obstacles in its path. Return the
collective stick to 50% and deactivate the Panic Recovery
Function to return to the current ight mode.
NOTICE: Before deactivating Panic Recovery, make
sure the collective stick has been returned to the
50% position. Once the Panic Recovery has been
deactivated, full negative collective becomes available,
which could cause the 230 S Smart to descend rapidly.
• This mode is intended to provide the pilot with the
condence to continue to improve their ight skills.
• Move the collective stick to 50% and return all other
transmitter controls to neutral for the quickest recovery.
• Once the model has reached a level upright attitude, the
negative collective is reduced to prevent the user from
pushing the model into the ground.

Control Tests
Ensure the throttle hold is ON when doing the direction
control tests. Test the controls prior to the rst ight to
ensure the servos, linkages and parts operate correctly.
If the controls do not react as shown in the illustrations
below, conrm the transmitter is programmed correctly
before continuing on to the Motor test.
Throttle Hold
Throttle hold is used to prevent the motor from powering
on inadvertently. For safety, turn throttle hold ON any time
you need to touch the helicopter or check the direction
controls.
Throttle hold is also used to turn off the motor quickly if the
helicopter is out of control, in danger of crashing, or both.
The blades will continue to spin briey when throttle hold
is activated.
Motor
Place the helicopter outdoors on a clean, at and level
surface (concrete or asphalt) free of obstructions. Always
stay clear of moving rotor blades.
CAUTION: Keep pets and other animals away
from the helicopter. Animals may injure themselves
if they attack or run toward the helicopter.
1. Conrm that throttle is at full low position.
2. Turn Throttle Hold OFF.
WARNING: Stay at least 30 feet (10 meters)
away from the helicopter when the motor is
running. Do not attempt to y the helicopter at
this time.
3. Slowly increase the throttle until the blades begin to
spin. The main blades should spin clockwise when
viewing the helicopter from the top. The tail rotor
blades should spin counterclockwise when viewing the
helicopter from the right side.
NOTICE: If the main rotor blades are spinning
counterclockwise, reduce the throttle to low immediately.
Disconnect the battery from the helicopter and reverse
any two motor wire connections to the ESC and repeat
the motor control test.
