Blade 120 SR RTF/BNF Introduction
The sub-micro Blade® 120 SR is a great way to graduate from coaxial helicopters to fixed-pitch single-rotor
helicopters. Its unique Bell-Hiller head design lets you enjoy the extra speed and agility of a single-rotor heli without
giving up a lot of the self-stabilizing characteristics you might be used to. The 120 SR also boasts the lightweight
durability of a carbon fiber main shaft and tail boom. And while it’s certainly small enough to fly indoors, the 120 SR
is big enough to fly in the backyard with a bit of a breeze. You can also adjust its control response rate and control
sensitivity for extra control authority when flying outdoors.
The Blade 120 SR ready-to-fly (RTF) model can be up and flying in the time it takes to charge the battery.
The Blade 120 SR bind-and-fly (BNF) model can be up and flying in the time it takes to charge the battery and bind
it to your transmitter.
Troubleshooting
If you encounter any difficulties with your Blade120 SR please refer to the troubleshooting guide at the back of the
manual. If you still encounter difficulties, see page 19 to contact the appropriate Horizon Product Support office.
In order to provide the best possible product, some parts may vary slightly from those shown.

Transmitter and Receiver Binding
If you purchased an RTF model, the transmitter is bound to the model at the factory.
To bind or re-bind your 120 SR to your chosen transmitter please follow the directions below:
Binding is the process of programming the receiver of the control unit to recognize the GUID (Globally Unique
Identifier) code of a single specific transmitter. You need to ‘bind’ your chosen Spektrum™ or JR® DSM2 technology
equipped aircraft transmitter to the receiver for proper operation.

A
Binding Procedure Reference Table
1. Refer to your transmitter’s unique instructions for binding to a receiver.
2. Make sure the flight battery is disconnected from the helicopter.
3. Power off the Blade MLP4DSM or your chosen transmitter.
4. Connect the flight battery in the helicopter. The 5-in-1 unit LED will begin to
flash. (Typically after 5 seconds).
ON B
5. Put your transmitter into bind mode. If using the Blade MLP4DSM
transmitter, push the left control stick vertically into the case until it clicks,
while powering on the transmitter.
6. Make sure transmitter controls are neutral and throttle is in low position.
7. The 5-in-1 unit status LED light will go from a flashing to a solid light. After
5 to 10 seconds the light will become solid indicating the receiver is bound
to the transmitter. Note: If the LED does not go to a solid light, refer to
Troubleshooting Guide at back of manual.
Additional Binding Information
Prior to each flight, power on your transmitter and wait about five seconds before you plug the flight battery into the
receiver. This allows time for the transmitter to scan and secure two open frequencies. If you plug the flight
battery in too quickly and miss the link, the receiver may inadvertently enter bind mode. If this occurs leave the
transmitter on, then disconnect and reconnect the flight battery.
Please avoid binding near large metal objects (furniture, vehicles, etc.), and binding with the transmitter too near
the aircraft. Please bind with transmitter at least 50cm (2 feet) from aircraft.
5-in-1 Control Unit Function Description
The unique Control Unit installed on your 120 SR is a lightweight combination of main motor electronic speed
controls, mixer, gyro, servos and Spektrum DSM2 compatible receiver. The 5-in-1 unit is also equipped with a
status indicator LED.
The following text describes how to make sure of arming, control unit operation and motor control:
❏❏ Before each flight, ALWAYS power on the
transmitter before connecting the flight battery to
the 5-in-1 unit. After each flight keep control of
the helicopter by disconnecting the flight battery
from the 5-in-1 unit before powering off the
transmitter.
Note: Installing the flight battery before powering
on the transmitter can start the Binding
process. Please see the Transmitter and
Receiver Binding section of this manual for
more information.
❏❏ The 5-in-1 unit will arm motors when the throttle
stick is in the lowest possible position, and the
throttle trim is also at the middle or a lower than
middle position (the middle position is indicated
by a longer than usual beep/tone). If this is the
first test flight, or a test flight following repairs,
also center the rudder, aileron and elevator trims.
IT
FR
❏❏ With the transmitter turned on and the transmitter
LED glowing solid RED, it is safe to connect the
flight battery to the 5-in-1 unit.
❏❏ Connect the flight battery to the 5-in-1 unit.
❏❏ After the flight battery is connected, the 5-in-1
unit status LED should glow solid RED within a
few seconds.
Note: DO NOT move, sway or pretend to fly the
helicopter after connecting the flight battery.
This movement can stop unit initialization
and gyroscope calibration. If the helicopter
is moved before the 5-in-1 unit status LED
glows solid RED, disconnect then connect
the flight battery to the 5-in-1 unit.
❏❏ When the 5-in-1 unit status LED glows solid RED,
the control unit is initialized and ready for flight.
Also, as long as you set the throttle stick and trim
to the correct positions during the initialization

process, the ESC or motors will be armed. Use
caution because after arming, rotor blades will
turn at throttle stick input.
Note: If the 5-in-1 unit status LED does not glow
solid RED, please review the following:
• When the 5-in-1 unit status LED is off
completely, you do not have a positive RF link
between the transmitter and receiver. Make
sure transmitter batteries and the flight battery
are fully charged. Make sure the transmitter
is powered on and that the transmitter LED
glows solid red. If the transmitter is powered on
and functioning properly, disconnect the flight
battery from the 5-in-1 unit, then reconnect the
flight battery. The 5-in-1 unit should initialize
and arm properly.
• When the 5-in-1 unit status LED glows solid
RED, but motors do not respond to throttle input,
there may be a positive Radio Frequency (RF)
link between the transmitter and receiver, but
the throttle stick and throttle trim may not be
set to the correct positions.
Make sure the throttle stick is in the lowest
possible position, and that the throttle trim is
set to the middle or a lower than the middle
position. The 5-in-1 unit may then arm the
motors within a few seconds.
Control Test
Test the controls prior to the first flight to ensure none of the servos, linkages or parts were damaged during
shipping and handling.
Turn the transmitter on first and lower the throttle stick completely. Then, plug the battery into the battery lead of
the 5-in-1 unit.
Transmitter Mode Legend
The colored arrows correspond to the following transmitter modes:
MODE 2
MODE 1
Note: Position helicopter to view the swashplate from behind the helicopter.
Move the elevator stick on the transmitter
forward and aft to check elevator pitch control.
When the elevator stick is pushed forward,
the left-hand servo linkage should push the
swashplate upward.
With the elevator stick pulled back, the lefthand servo linkage should pull the swashplate
downward.
Move the right-hand stick left and right to
check aileron roll control. When the aileron

If at any time during the test the controls respond in the opposite direction, reverse/change the direction of
operation of the flight controls. Follow these steps to change the direction of the various flight controls:
1. B
e certain that battery is disconnected from the battery lead of the 5-in-1 control unit and the transmitter is
turned off.
2. P ush down on the appropriate digital trim button on the transmitter for the control you would like to change
the direction of. For example:
Top elevator button
Elevator channel normal
Bottom elevator button
Elevator channel reversed
Left aileron button
Aileron channel normal
Right aileron button
Aileron channel reversed
Left rudder button
Rudder channel normal
Right rudder button
Rudder channel reversed
3. Continue to hold the appropriate trim button while turning the transmitter on.
4. Hold the digital trim button down for approximately five seconds, until a series of beeps/tones are heard
confirming the selection.
5. Connect the battery to the 5-in-1 and complete the flight control test. Confirm that all controls operate in the
correct directions.
If you decide to use an E-flite LP5DSM transmitter, position your channel
reversal dip switches as the figure on the right. If you’ve confirmed proper
control operation of your Blade 120 SR, unplug the flight battery.

Channel 5 affects rate settings of the 5-in-1 Control Unit.
• If using the stock MLP4DSM Transmitter, please read page 12 of this manual for Dual Rate information.
• If using an LP5DSM Transmitter, please turn the Channel 5 knob clockwise completely for the highest control
rates possible.
• If using any other DSM2 compatible transmitter, please ensure Channel 5 output is set to full travel.
Note: Test this by inducing full cyclic (Aileron/Elevator) input and moving the switch or knob. There’s
approximately 10–15% less servo travel if the Channel 5 position is set wrong.
Motor Control Test
• P lace the helicopter on a clean and flat ground surface (linoleum, concrete or asphalt) free of obstructions.
Always stay clear of the moving rotor blades.
CAUTION: K eep pets and other animals away from the helicopter. Animals may injure themselves if they
attack or run from the helicopter.
• Move the throttle stick a small amount until rotor blades turn. DO NOT attempt to fly the helicopter.
• When viewed from the top, the main rotor blades should turn clockwise.
• When viewed from the tail rotor side of the helicopter, the tail rotor blades should turn counterclockwise.
• If either set of blades turns in the wrong direction, disconnect the flight battery and contact Horizon Customer
Service for information.
• If the tail rotor turns clockwise, tail motor wiring connectors may be disconnected. Connect the wiring at the
motor in reverse so the tail rotor turns counterclockwise.
• After confirming the rotor blades rotate in the correct direction, motor response to controls can be tested.
• Adjust the throttle to a low level of power then move the rudder (left-hand) stick a small amount to the right.
The nose of the helicopter should move to the right.
• Move the rudder stick a small amount to the left. The nose of the helicopter should move to the left. If the
nose moves to the right, please refer to the Troubleshooting Guide.
• When rotors turn correctly and respond correctly to controls, your 120 SR is ready for first flight.

Understanding the Primary Flight Controls
If you are not familiar with the controls of your 120 SR, take a few minutes to familiarize yourself with them before
attempting your first flight.
Transmitter Mode Legend
The colored arrows correspond to the following transmitter modes:
MODE 2
MODE 1
When the throttle stick is in the lowest possible
position and throttle trim is set to the middle or
a lower than the middle position, the main
rotor blades will not spin. Advancing the
throttle stick upward increases the speed
of the main rotor blades, causing the model
to climb.
Climb
Decreasing the speed of the main rotor blades
by lowering the throttle stick causes the model
to descend.
Descend
Once the model is off the ground, balance the throttle by carefully moving the throttle stick up and down so the
model holds a stationary hover (without climbing or descending).
10
Moving the rudder stick to the left turns the
nose of the helicopter left about the axis of the
main shaft.
Nose Yaws Left
Moving the rudder stick to the right turns the
nose of the helicopter right about the axis of
the main shaft.
Nose Yaws Right
EN
DE
FR
IT
Use rudder trim to help keep the nose of the helicopter from rotating left or right when in hover with no rudder stick
input. For example, if the nose of the helicopter drifts to the right when in hover, add left rudder trim (by pressing
and releasing the left rudder trim button) until the nose stays as near straight as possible.
Forward
The elevator stick controls both elevator (pitch
fore/aft). Push the stick forward to pitch the
nose of the helicopter down and fly forward.
Backward
Pull the elevator stick back to pitch the tail
down and fly backward.
Use elevator trim to keep the helicopter from drifting forward or backward when hovering with no elevator stick
input. For example, if the helicopter drifts forward, add back/up elevator trim until it hovers as level as possible with
no drifting.
Move the aileron stick left to fly the
helicopter left.
Left
Move the aileron stick right to fly the helicopter
to the right.
Right
Use aileron trim to keep the helicopter from drifting left or right when hovering with no aileron stick input. For
example, if the helicopter drifts to the right when hovering, add left aileron trim until it hovers as level as possible
with no drifting to the right. Once familiar with the primary controls of the helicopter, you are almost ready to fly.

Dual Rates
Your 120 SR RTF model comes with the Blade MLP4DSM transmitter. This transmitter’s dual rate feature lets the
pilot change between high and low control rates for the aileron, elevator, rudder and throttle channels.
• When powered on, this transmitter is automatically in high-rate mode.
• Change rate modes by pushing the right-hand control stick down into the case until it clicks while the
transmitter is powered on.
• High-rate mode is shown by the transmitter’s LED glowing solid red. In high-rate mode the controls can reach
their maximum values. This mode is typically preferred by experienced pilots for maximum control authority.
• Low-rate mode is shown by the transmitter’s LED blinking continuously. In low-rate mode the controls are
reduced to a percentage of their maximum values. This mode is typically preferred by (and best for) first-time,
low-time and other pilots interested in smoother and more easily controlled hovering and flying.

Consult local laws and ordinances before choosing a
location to fly your aircraft.
When ready for your first flight, select a relatively open indoor WIND
area free of people and obstructions. While it is possible for
experienced pilots to fly the 120 SR in relatively small indoor
areas with great success, we strongly recommend an area
with at least 10-feet by 10-feet of floor space and no less than
8-foot ceilings when making your first few flights.
Once you properly trim your helicopter and become familiar
with its handling and capabilities, you will be able to fly in
other smaller, less open areas.
Flying the 120 SR
Note: In addition to reviewing the flight maneuvers outlined below, we recommend you watch Videos located
on the product page for the 120 SR on www.bladehelis.com to see many of these maneuvers and
adjustments performed by the helicopter and pilot.

• L ift the model off the ground just a few inches and concentrate on balancing the throttle stick position so
that the model holds a steady hover altitude. In some cases you may need to make a few short “hops” to
an altitude of just a few inches until familiar with the control inputs and trim settings required to maintain a
steady hover and altitude.
The 120 SR requires minor throttle adjustments to maintain its altitude in hover. Remember to keep these
throttle adjustments as minimal as possible as large adjustments could result in a loss of control and/or a
possible crash.

• W
hile attempting to establish a low-level hover, you can also check to see if any trim adjustments are
required to help keep the 120 SR from constantly drifting in various directions. If you find the helicopter
constantly drifts without any directional control input, land the model before making any adjustments to the
trim settings. Additional details regarding the location and function of the trim buttons are in the
“Understanding the Primary Flight Controls” section of this manual.
- If the nose of the helicopter drifts to the left or right, adjust the rudder trim.
- If the helicopter drifts forward or backward, adjust the elevator trim.
- If the helicopter drifts to the left or right, adjust the aileron trim.
Continue making trim adjustments until the helicopter hovers at a low altitude with very little drifting and
directional control input. If the 120 SR is your first helicopter model, seek help of an experienced pilot to trim
the model for you before making your first flight.
• With your 120 SR properly trimmed and maintaining a stable low-level hover, practice using the rudder,
elevator and aileron controls to familiarize yourself with the helicopter’s responses to control inputs.
Remember to keep the control inputs as minimal as possible.
When comfortable with low-level hovering, you can transition to hovering and flying the helicopter at
higher altitudes of three to four feet. At these higher altitudes you will become comfortable with the flight
characteristics of the 120 SR.
• If you feel the helicopter drifting out of control during flight, release all of the controls except for throttle. You
will need throttle to maintain altitude, but because of the inherent stability of the self-stabilizing single rotor
design, the 120 SR will return to a stable hover on its own, if space allows.
• Don’t be afraid to set the helicopter down on the ground quickly by lowering the throttle when
approaching walls or other obstacles to help prevent main rotor blade strikes.
CAUTION: Always fly the helicopter with your back to the sun and the wind to prevent loss of flight control.
Once you have gained experience and confidence in hovering the 120 SR, you can attempt more advanced
maneuvers including:
Forward Flight
Pirouettes
Backward Flight Spot Landings
Advanced Swashplate Settings
Skidding Takeoffs
Skidding Landings
Short Swashplate Control Balls Swashplate Ball Link
Adjustment
The Blade 120 SR comes with an adjustable
swashplate. Advanced pilots may benefit from a
more aggressive setup. To achieve a more
aggressive setup, pop off the lower rotor head
links and move them onto the longer set of inner
swashplate control balls.
Note: Always attach links to control balls
opposite each other.

Maintenance

setting
Do regular maintenance to keep your Blade 120 SR in safe flying condition.
Ball
Links
Make sure a 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 flight and cause a crash. Replace
worn ball links before they fail.
Cleaning
Make sure 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 wiring does not block 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 screw so parts are mated together, then turn 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 flying.
