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.

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.

Flying the 230 S Smart
Consult your local laws and ordinances before choosing a
location to y your aircraft.
We recommend ying your aircraft outside in calm winds
or inside a large gymnasium. Always avoid ying near
houses, trees, wires and buildings. You should also be
careful to avoid ying in areas where there are many
people, such as busy parks, schoolyards or soccer elds.
It is best to y from a smooth at surface as this will allow
the model to slide without tipping over. Keep the helicopter
approximately 2 ft (600mm) above the ground. Keep the
tail pointed toward you during initial ights to keep the
control orientation consistent. Releasing the stick in Stabil-
ity Mode will allow the helicopter to level itself. Activating
the Panic Recovery button will level the helicopter quickly.
If you become disoriented while in Stability Mode, slowly
lower the throttle stick to land softly.
During initial ights, only attempt takeoff, landing and
hovering in one spot.
Takeo
NOTICE: If the main motor or tail motor do not start
up properly when throttle is rst applied, immediately
return the throttle to the low position and try again. If the
problem persists, disconnect the ight battery, check
for binding in the gear train and ensure no wires have
become entangled within the gears.
Place the model onto a at, level surface free of obstacles
and walk back 30 feet (10 meters). Slowly increase the
throttle until the model is approximately 2 ft. (600mm) off
the ground and begin ying the model.
Hovering
Making small corrections on the transmitter, try to hold
the helicopter in one spot. If ying in calm winds, the
model should require almost no corrective inputs. After
moving the cyclic stick and returning it to center, the
model should level itself. The model may continue to
move due to inertia. Move the cycle stick in the opposite
direction to stop the movement.
After you become comfortable hovering, you can progress
into ying the model to different locations, keeping the tail
pointed towards you at all times. You can also ascend and
descend using the throttle stick. Once you’re comfortable
with these maneuvers, you can attempt ying with the tail
in different orientations. It is important to keep in mind
that the ight control inputs will rotate with the helicopter,
so always try to picture the control inputs relative to the
nose of the helicopter. For example, forward will always
drop the nose of the helicopter.
Low Voltage Cuto (LVC)
LVC decreases the power to the motors when the battery
voltage gets low. When the motor power decreases and
the red LED on the ESC ashes, land the aircraft immedi-
ately and recharge the ight battery.
LVC does not prevent the battery from over-discharge
during storage.
NOTICE: Repeated ying to LVC will damage the battery.
Landing
To land, slowly decrease the throttle while in a low-level
hover. After landing, disconnect and remove the battery
from the aircraft after use to prevent trickle discharge.
Review your manufacturers provided LiPo guidelines for
charging and storage information.
Use your mobile
device on this QR
code which will
link you to a video
covering the basics of
ying the 230s Smart.
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 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.

The 230 S Smart BNF ight controller may be programmed
from any compatible Spektrum transmitter
(visit SpektrumRC.com for more information).
The ight controller shipped with BNF models has a range
of adjustable parameters suitable for the 230 S Smart
Helicopter and is not intended for use in other aircraft.
It is important to use the included servos with the BNF
ight controller because the adjustable parameters
available for the SPMAR6250MHX are designed around
the recommended servos. It is possible there may not be
enough range for the helicopter to be tuned when using
alternative servos.
Entering the Advanced Parameters Menu
With the helicopter bound to the transmitter and powered on, enter the Function List and select Forward Programming.
The list of adjustable parameters and the range of values available for tuning have been tailored for this helicopter. Make
small changes to one parameter at a time and test y the changes before changing the parameter further or changing a
different parameter.

The advanced tuning options must be entered within 30 seconds after initialization completes. In addition the combina-
tion of dual rates and travel adjustments must result in a throw greater than 65% in order to enter the tuning modes.
Entering Servo Adjustment Mode
1. Lower the throttle stick to the lowest position.
2. Power ON the transmitter and activate throttle hold.
3. Install the ight battery on the helicopter frame,
securing it with the hook and loop strap.
4. Connect the battery connector to the ESC.
5. After initialization is complete (indicated by a slow
green ash), hold the left stick to the bottom left corner
and the right stick to the bottom right corner as shown.
6. Servo Adjustment Mode is indicated by the swashplate
servos jumping and then slowly moving back to center.
7. Release the sticks and proceed to the next step.
Adjusting the Servo Neutral Position
With the model in Servo Adjustment Mode, the control stick
and gyro inputs are disabled and the servos are held in the
neutral position. Check the position of the servo arms to
verify they are perpendicular to the servos.
• If the arms are perpendicular to the servos, no adjust-
ment is necessary.
Exit Servo Adjustment Mode.
• If one or more servo arm is not perpendicular to the
servos, continue the servo adjustment process.
While watching the swashplate servos, apply fore or aft
cyclic and release. One of the servos will jump, indicating
the selected servo. Apply fore or aft cyclic and release until
the servo that needs to be adjusted is selected.
Once the servo you wish to adjust is selected, move the
cyclic stick left or right to adjust the servo neutral position
in the desired direction.
To reset the current servo to the default neutral position, hold
the rudder stick full right for two seconds.
The range of adjustment is limited. If you are unable to
adjust the servo arm to be perpendicular to the servo, you
must reset the servo to the default neutral position, remove
the servo arm and place it back onto the servo as close to
perpendicular as possible. You may then adjust the servo
neutral position using left or right cyclic stick.
Swashplate Leveling
Before saving your adjustments and exiting servo
adjustment mode, verify the swashplate is level and both
main rotor blades are at 0 degrees pitch.
If they are not, make linkage adjustments as necessary.
Saving the Servo Adjustments
1. Lower the throttle stick to the lowest position and
release the sticks.
2. Move the tail rotor stick to the left and hold for four
seconds to exit Servo Adjustment Mode. The servos will
jump indicating a return to normal operation.
3. Release the tail rotor stick.
4. Perform the pre-ight checklist procedure before ying
your model.
Advanced Tuning (Non-Forward Programming)
Applies to Spektrum transmitters not capable
of forward programing including
DX6i, DX6e, DX7s DX8, and DX8e
Your Blade 230 S Smart was setup at the factory and test
own. The servo adjustment steps are usually only neces-
sary in special circumstances, such as after a crash or if a

Trim Flight
Perform this procedure if the model is not performing well or
has been recently rebuilt from a crash.
The trim ight procedure was performed during the factory
test ight and only needs to be performed if you notice the
model is not returning to level consistently or if the model
does not remain still during stationary pirouettes.
The trim ight is used to determine the optimal settings for
SAFE®technology during ight.
The trim flight must be performed in calm conditions.
Performing the Trim Flight
1. Slowly increase the throttle to lift the model into a
stationary hover. Make corrections as necessary
to keep the model still. Evaluation does not begin
until the throttle stick is over 50% and the sticks are
centered. Making corrections will not affect the result
but a longer ight may be necessary.
2. Keep the model stationary in a hover for 120 seconds.
Sliding and slow movements are okay. The main goal
is to keep the rotor disk level.
3. Once you are satised with the trim ight, land the model.
Exiting Trim Flight Mode
1. After landing, lower the throttle stick to the lowest
position.
2. Activate Panic Recovery for 2 seconds, or until the
swashplate moves, indicating the servo positions and
attitude values have been recorded and trim ight
mode has been exited.
Flight Test
After performing the trim ight, test-y the model to evalu-
ate the leveling characteristics.
• The model should return to level ight consistently.
• During takeoff, the model should lift off with minimal
corrections.
• During a hover, the control stick should remain close to
center. Small corrections are acceptable.
If the model performs poorly or does not level properly after
the trim ight, retry the entire trim ight procedure. If the
problem persists, inspect the model for damaged compo-
nents, a bent shaft or anything that may result in increased
vibration. The trim ight may not record the correct values
due to excessive vibration, ying in wind or the model
not staying level. In these cases, shorter trim ights may
be necessary. If you are still experiencing problems after
several attempts please perform the calibration procedure
and try the trim ight procedure again.

Calibration Procedure DXS (RTF)
Wiring Order On AR6250MHX Recevier
To perform the calibration procedure:
1. Ensure the surface used for calibration is level.
2. Power on the transmitter and helicopter, allowing them
to initialize.
3. Turn Throttle Hold ON.
4. Ensure the main motor and tail motor leads
are disconnected. Set the ight mode switch to
Intermediate Mode (FM1).
5. Using a bubble level as shown below, level the helicopter
by placing the Blade 230 S Smart foam blade holder
under the tail n. Use additional items, as necessary, to
build up under the tail n until the tail boom is level.
6. Hold the left stick
to the bottom
right corner, the
right stick to the
upper left corner
and activate the
Panic Recovery
function until the LED on the receiver ashes once.
7. Release both sticks and deactivate the Panic Recovery
function.
8. The LED on the receiver will remain solid for 1-2
minutes while the calibration takes place. Do not move
the helicopter until the calibration is completed. If the
LED begins blinking rapidly, an error has occurred. Begin
the calibration procedure again, starting with step 1.
9. After the calibration is successfully completed, the receiver
LED will blink slowly (2 seconds on, 2 seconds off).
10. Power the helicopter off.
11. Reconnect the main motor and tail motor wires.
12. Perform the trim ight procedure.
13. During subsequent ights after the trim ight, the helicopter
should return to within 5 degrees of level consistently.

Post-Flight Inspection and Maintenance Checklist
√
Ball Links
Make sure the plastic ball link holds the control ball, but is not tight (binding) on the ball. When a link
is too loose on the ball, it can separate from the ball during ight and cause a crash. Replace worn
ball links before they fail.
Cleaning Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush or
a dry, lint-free cloth.
Bearings Replace bearings when they become notchy (sticky in places when turning) or draggy.
Wiring Make sure the wiring does not contact moving parts. Replace damaged wiring and loose connectors.
Fasteners
Make sure there are no loose screws, other fasteners or connectors. Do not over-tighten metal
screws in plastic parts. Tighten screws so the parts are mated together, then turn the screw only
1/8th of a turn more.
Rotors
Make sure there is no damage to rotor blades and other parts which move at high speed. Damage
to these parts includes cracks, burrs, chips or scratches. Replace damaged parts before ying. Verify
both main rotor blades have the correct and equal tension in the blade grips. When the helicopter is
held up sideways, the main blades should support their own weight. When the helicopter is shaken
lightly, the blades should fall.
Tail
Inspect the tail rotor for damage and replace if necessary. Verify the tail motor bolts, tail rotor adapter
bolts and tail motor mount bolts are properly tightened. Inspect the tail boom for any damage and
replace if necessary.
Mechanics
Inspect the main frame and landing gear for damage and replace if necessary. Check the mainshaft
for vertical play and adjust the locking collar if necessary. Verify that the main gear mesh is correct
and that no tight spots exist in the 360 degree rotation. Inspect all wires for damage and replace as
necessary.

shakes in ight
Damaged rotor blades, spindle or
blade grips
Check main rotor blades and blade grips for cracks or
chips. Replace damaged parts. Replace bent spindle
Random movements in
ight Vibration
Verify the receiver is properly attached to the
helicopter. Inspect mounting tape for damage. Verify
that no wires are contacting the receiver. Inspect and
balance all rotating components. Verify the main shaft
and tail rotor adapter are not damaged or bent. Inspect
mechanics for broken or damaged parts and replace
as necessary
Tail oscillation/wag or poor
performance
Damaged tail rotor, main gear
mesh, loose bolts, vibration
Verify that the boom support bolts are tight and the
plastic boom support ends are properly adhered to the
boom support rods. Inspect the tail rotor for damage.
Verify that all bolts on the tail assembly are properly
tightened. Verify main gear mesh and ensure no tight
spots in the mesh through full rotation. Replace any
damaged or worn components
Drift in calm winds Vibration, damaged linkage,
damaged servo
Under normal operation the transmitter trims should
not require adjustment and the center positions are
memorized during initialization. If you nd that trim
adjustments are necessary after take off, verify the
balance of all rotating components, ensure the
linkages are not damaged and make sure the servos
are in proper working condition
Drift in wind Normal
The model will drift with the wind but should remain
level in ight. Simply hold the cyclic stick in the neces-
sary position to keep the model stationary. The model
must lean into the wind to remain stationary, if the
model remains level then it will drift with the wind
