Battery Warnings and Guidelines
While the 1S 3.7V DC Lithium Polymer Battery Charger (EFLC1103)
included with your Blade mCX has been specifically designed
to safely charge the included 1S 3.7V 110mAh Lithium Polymer
Battery (EFLB1101S), you MUST read the following safety
instructions and warnings before handling, charging or using the
LiPo battery.
Note: Lithium Polymer batteries are significantly more volatile than
the alkaline, NiCd or NiMH batteries used in RC applications. All
instructions and warnings must be followed exactly. Mishandling of
LiPo batteries can result in fire.
By handling, charging or using the included LiPo battery
you assume all risks associated with lithium batteries.
If you do not agree with these conditions, return your
complete Blade mCX model in new, unused condition to
the place of purchase immediately.
• You must charge the included 1S 3.7V 110mAh LiPo battery in a safe
area away from flammable materials.
• Never charge the battery unattended. When charging the battery you
should always remain in constant observation to monitor the charging
process and react to potential problems that may occur.
• Find a suitable area for flying
Flying Checklist
Please note this checklist is not intended to be a replacement for the
content included in this instruction manual. Although it can be used as
a quick start guide, we strongly suggest reading through this manual
completely before proceeding.
• After flight, the battery must be cooled to ambient temperature before charging.
• You MUST use the included 1S 3.7V DC LiPo Charger (EFLC1003)
ONLY. Failure to do so may result in a fire causing personal injury
and/or property damage. DO NOT use a NiCd or NiMH charger.
• Always turn the transmitter on first
• Plug the flight battery into the lead from the 5-in-1 control unit
• Allow the 5-in-1 control unit to initialize and arm properly
• Fly the model
• Land the model
• Unplug the flight battery from the 5-in-1 control unit
• Always turn the transmitter off last

• If at any time during the charge or discharge process the battery
begins to balloon or swell, discontinue charging or discharging
immediately. Quickly and safely disconnect the battery, then place
it in a safe, open area away from flammable materials to observe
it for at least 15 minutes. Continuing to charge or discharge a
battery that has begun to balloon or swell can result in a fire. A
battery that has ballooned or swollen even a small amount must
be removed from service completely.
• Store the battery at room temperature in a dry area for best results.
• When transporting or temporarily storing the battery, the temperature
range should be from 40–120 degrees Fahrenheit. Do not store the
battery or model in a car or direct sunlight whenever possible. If stored in
a hot car, the battery can be damaged or even catch fire.
• Do not over-discharge the LiPo flight battery. Discharging the
battery too low can cause damage to the battery resulting in
reduced power, duration or failure of the battery entirely.
LiPo cells should not be discharged to below 3V each under load. In
the case of the 1S LiPo battery used for the Blade mCX, you will not
want to allow the battery to fall to below 3V during flight.
The Blade mCX’s 5-in-1 control unit features a soft low voltage
cutoff (LVC) that occurs when the battery reaches 3V under load.
When the soft cutoff occurs, the ESCs of the 5-in-1 unit will reduce
power to the motors (regardless of the power level you have set with
the throttle stick) in order to prevent the voltage of the battery from
dropping below 3V. This reduction in power usually requires that
you land the model immediately, at which point you should power
down the model and unplug the flight battery.
And while it is possible to power the model up and to fly again
after the soft LVC occurs, this is NOT recommended as continued
discharging to the soft LVC will cause permanent damage to the
LiPo battery that results in lost power and duration when using
the battery for subsequent fights, or failure of the battery entirely.
Continued attempts to further discharge the battery may also result
in loss of control while the motors are running as the voltage of
the battery may drop below the minimum operating voltage of the
receiver and other electronics.
helicopter begins to require more throttle than typical to maintain
hover or flight, you should land the helicopter immediately.
Routinely discharging the battery to the soft LVC can still cause
permanent damage to the battery.
Note: When the battery power/voltage is getting low you will typically find
that significant rudder trim and/or rudder stick adjustments are needed
to prevent the helicopter from spinning. This usually occurs before soft
LVC, and indicates a good time to stop flying.
If you have any further questions or concerns regarding the handling,
charging and/or use of the included Li-Po battery pack, please contact
Horizon Support Team at 877-504-0233.
Battery Charging
It is important that you only charge the included 1S 3.7V 110mAh
LiPo Battery (EFLB1101S) with the included 1S 3.7V DC LiPo
Charger (EFLC1003). Attempting to charge the battery using
another LiPo charger or non-LiPo compatible charger could result
in serious damage. Please familiarize yourself thoroughly with the
Battery Warnings and Guidelines section before continuing.
Please follow these steps to charge the LiPo battery with the included
charger:
• Remove the cover on the bottom of the charger and install four of the
included AA batteries, noting proper polarity. Replace the cover after the
AA batteries are installed.
• Slide the battery into the slot on the charger. The endcap of the battery
has been specifically designed to allow the battery to be slid into the slot
easily one way (usually with the label on the battery facing outward) to
prevent reverse polarity connection. However, please be sure to check
for proper alignment and polarity before proceeding to the next step.
Also, it is not recommended that you fly to the soft LVC every
time you fly. Instead, you should be aware of the power level of
the battery/helicopter throughout the flight, and if at any time the

• Gently press the battery and its connector into the charge jack/connector
located at the bottom of the slot on the charger. Again, be sure to check
for and to achieve proper polarity before making the connection.
• After you make the connection successfully, the LED light on the charger
will turn solid red, indicating that charging has begun.
• It will take approximately 30–40 minutes to charge a fully discharged (not
over-discharged) battery. As the battery nears full charge, the LED light
will begin to blink. When the battery is fully charged the LED light will blink
approximately every 20 seconds or will go out entirely.
Note: The LiPo battery included with your Blade mCX will arrive partially
charged. For this reason the initial charge may only take 15–20 minutes.
Note: You can expect to charge the LiPo flight battery approximately
15–20 times before it will be necessary to replace the AA batteries in the
charger. Replacing the included batteries with alkaline batteries will extend
the AA battery life.
Installing the Flight Battery
Once the LiPo battery has been fully charged, it’s ready to be installed in the
helicopter.
Install the battery in the helicopter by sliding it into the battery mounting
supports/slots just below the main gears. Slide the battery into the slots
with the label facing downward and the connector oriented toward the back
of the helicopter.
Note: Be sure to slide the battery into the slots until the endcap of the
battery comes into contact with the rear battery support. This will allow
you to achieve the correct center of gravity for the best overall flight
performance. However, also be sure that the battery is not pushed far
enough forward that it will make contact with the servo gears as this could
cause damage to the gears and a potential crash.
Transmitter Preparation
Please make sure you have fresh/charged batteries in your transmitter.
If applicable, set your transmitter model to Airplane. JR/Spektrum
transmitters servo settings should be set to default (normal) servo direction.
Futaba transmitters (equipped with Spektrum modules) may require you to
reverse the throttle channel.
Transmitter and Receiver Binding
Binding is the process of programming the receiver of the 5-in-1 control unit
to recognize the GUID (Globally Unique Identifier) code of a single specific
transmitter. It will be necessary for you to ‘bind’ your chosen Spektrum
DSM2 technology equipped transmitter to the receiver/5-in-1 for proper
operation.
The following is a list of some of the Spektrum DSM2 equipped transmitters
and modules that will bind to the receiver/5-in-1 of the Blade mCX:

Control Test
Although in most cases your transmitter of choice will offer full and proper
control of the Blade mCX BNF with ‘standard’ settings (standard airplane
mode, servo reversing set to normal, travel adjustments set to 100%, etc.),
you must test the controls prior to the first flight to ensure none of the
servos, linkages or parts were damaged during shipping and handling and
that the controls function in the correct directions.
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.
Note: The connectors on the battery and battery lead are keyed to prevent
reverse polarity connection. However, if you force them together in the
wrong orientation and with the wrong polarity it is still possible to damage
the battery and/or 5-in-1 unit. To help further prevent a reverse polarity
connection, one side of the endcap on the battery and the connector on
the battery lead of the 5-in-1 unit will have a red dot. The connectors are
oriented for a proper polarity connection when the red dots are on the same
side (usually toward the top of the helicopter).
Move the elevator stick on the transmitter forward and aft to check elevator
pitch control. When the stick is pushed forward, the right-hand servo (when
viewing the helicopter from behind) should pull the swashplate downward.

The following checklist contains the steps you must follow to ensure proper
arming and operation of the 5-in-1 unit, as well as proper motor response:
• Each time before you fly you should ALWAYS turn the transmitter on before connecting the flight battery to the 5-in-1 unit. Never connect the flight battery to the 5-in-1 unit before powering the transmitter on first. After each flight, be sure that you always disconnect the flight battery from the 5-in-1 unit before powering the transmitter off.
Mode 2
Mode 1
Note: The only time you should connect the flight battery to the
5-in-1 unit before powering the transmitter on is when you are
binding the receiver of the 5-in-1 unit to the transmitter. Please
see the Transmitter and Receiver Binding section of this manual for
more information.
If at any time during the test the controls respond in the opposite direction,
it may be necessary to reverse/change the direction of operation of the
flight controls. Follow your transmitter instructions to change the direction of
the various flight controls:
Once you’ve reconfirmed the flight control directions, all controls should be
functioning properly. However, if you continue to encounter any problems
with your Blade mCX responding properly to the transmitter, do not fly. Call
the Horizon Support Team at 1-877-504-0233.
• The throttle stick MUST be set in the lowest possible position, and,
for most transmitters, the throttle trim must also be set to the
lowest possible position in order for the 5-in-1 unit to arm.
If this is the first test flight, or a test flight following repairs, you should also
center the rudder, aileron and elevator trims.

The unique 5-in-1 Control Unit installed on your Blade mCX 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.
Note: It is extremely important that you do not move or sway the
helicopter once you connect the flight battery. If you do move the
helicopter while the 5-in-1 is initializing, disconnect the flight battery from
the 5-in-1 unit and repeat the initialization process.

• When the status LED becomes solid red, the 5-in-1 unit is initialized and
ready for flight. Also, as long as you had the throttle stick and trim set the
correct positions during the initialization process, the ESCs/motors will
now be armed. Use caution as both rotor blades will now spin with throttle
stick input.
Note: If the status LED does not become solid red, please review the
following:
• If after blinking red the status LED becomes solid red, but you have no control of the motors, you have 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. Check to be sure that 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. If you now have control of the motors, proceed to the next step of the checklist.
• If the blinking red status LED keeps flashing, you do not have a positive
RF link between the transmitter and receiver. Check to be sure that
the transmitter has been powered on and that the LED indicator on the
transmitter is glowing solid red. If the transmitter is powered on and
functioning properly, disconnect the flight battery from the 5-in-1 unit, then
reconnect it. Now the 5-in-1 unit should initialize and arm properly.
Note: In the event you inadvertently enter Bind Mode, the LED will
be flashing red continuously. If this occurs, cycle flight battery while
the transmitter is on (If previously bound).
If your 5-in-1 unit will not initialize and arm after following the guidelines as
listed above, call the Horizon Support Team at 1-877-504-0233.
• Once you have placed the helicopter in a safe area, free of obstructions, and are clear of the rotor blades, you can safely
begin to power up the model to check for proper operation of the
motors.
• Advance the throttle stick upward slowly, just until both rotor blades begin
to spin. DO NOT attempt the fly the helicopter at this time. Note the
direction that each of the rotor blades spins. When viewed from the top,
the upper main rotor blades should spin counter clockwise and the lower
main rotor blades should spin clockwise. If either set of rotor blades is
operating in the wrong direction, disconnect the battery and reverse the
polarity of the corresponding motor’s input power leads.
correct, it is best to confirm that both rotor blades respond properly to
rudder control inputs.
With the rotor blades spinning at a low level of power, move the rudder stick
all the way to the right. This should cause the speed of the upper main rotor
blade to increase, and the speed of the lower main rotor blade to decrease.
Next, move the rudder stick all the way to the left. This should cause the
speed of the lower main rotor blade to increase and the speed of the
upper main rotor blade to decrease. If both rotor blades are not responding
properly to rudder input, simply swap the locations of their motor plugs on
the 5-in-1 unit.
After confirming that both rotor blades are rotating in the correct directions,
and are responding properly to rudder inputs, your Blade mCX is ready
for flight. However, please be sure to review the following sections of the
manual BEFORE proceeding with the first flight.
Understanding the Primary Flight Controls
If you are not familiar with the controls of your Blade mCX,
please take a few minutes to familiarize yourself with them before
attempting your first flight.
The throttle stick on the transmitter controls throttle (climb/descend). 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 stick upward will increase the speed of the main rotor
blades. Increasing the speed of the main rotor blades will cause the model
to climb.
Note: The E-flite MLP4DSM transmitter is shown for reference only.
Mode 2
Climb
Mode 1
• After confirming that the direction of rotation for both rotor blades is
18
19
Decreasing the speed of the main rotor blades by lowering the throttle stick
will cause the model to descend.
Mode 2
Moving the stick to the right will turn (yaw) the nose of the helicopter to
the to the right about the axis of the main shaft. This is accomplished by
increasing the speed of the upper main rotor blade while decreasing the
speed of the lower main rotor blade.
Mode 2
Nose Yaws Right
Mode 1
Mode 1
Descend
After lifting the model off the ground you can balance the throttle by
carefully moving the throttle stick up and down so the model will hold a
stationary hover without climbing or descending.
Moving the rudder stick to the left will turn (yaw) the nose of the helicopter
to the left about the axis of the main shaft. This is accomplished by
increasing the speed of the lower main rotor blade while decreasing the
speed of the upper main rotor blade.
Mode 2
Nose Yaws Left
Mode 1
The rudder trim can be used to help keep the nose of the helicopter from
rotating to the 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 the left-hand rudder trim button) until the nose
stays as close to straight as possible.
The elevator stick controls pitch fore/aft. Pushing the stick forward will pitch
the nose of the helicopter downward, allowing the helicopter to be flown
forward.
Mode 2
Helicopter Moves Forward
Mode 1
20
21
Pulling the stick backward will pitch the tail of the helicopter downward,
allowing the helicopter to be flown backward.
Mode 2
Helicopter Moves Backward
Mode 1
Moving the aileron stick to the right will roll the helicopter to the right,
allowing the helicopter to be flown to the right.
Mode 2
Helicopter Slides Right
Mode 1
The elevator trim can be used to help keep the helicopter from drifting
forward or backward when in hover with no elevator stick input. For
example, if the helicopter drifts forward when in hover, add back/up elevator
trim until the helicopter hovers as level as possible with no forward drifting.
Moving the aileron stick to the left will roll the helicopter to the left, allowing
the helicopter to be flown to the left.
Mode 2
The aileron trim can be used to help keep the helicopter from drifting left or
right when in hover with no aileron stick input. For example, if the helicopter
drifts to the right when in hover, add left aileron trim until the helicopter
hovers as level as possible with no drifting to the right.
Once you’re familiar with the primary controls of the helicopter, you are
almost ready to fly.

Choosing a Flying Area
When you are ready for your first flight, you will want to select a relatively
open indoor area that is free of people and obstructions. And while it is
possible for experienced pilots to fly the Blade mCX in relatively small indoor
areas with great success due to its size and controllability, 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 have properly trimmed your helicopter and become familiar with
its handling and capabilities, you will be able to fly in other smaller, less
open areas.
Note: The Blade mCX is designed and intended to be flown INDOORS ONLY.
Flying the Blade mCX
Having followed the proper 5-in-1 control unit initialization and arming
procedures, confirmed proper control of the servos and motors, and found
a suitable flying area, your Blade mCX is ready for flight.
Note: In addition to reviewing the flight maneuvers outlined below,
we recommend that you watch the Instructional Video located on
the product page for the Blade mCX on www.horizonhobby.com to
see many of these maneuvers and adjustments performed by the
helicopter and pilot.
• Slowly raise the throttle stick, increasing the speed of the main rotor
blades until the model begins to lift off. Do not raise the throttle stick too
quickly as the model could climb too fast causing you to lose control or
make contact with objects above.
24
• Lift 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 it may be best to make a few short “hops”
to an altitude of just a few inches until you become familiar with the
control inputs and trim settings required to maintain a steady hover and
altitude.
As you will find, the Blade mCX 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.
• While attempting to establish a low-level hover, you can also check to
see if any trim adjustments are required to help keep the Blade mCX
from constantly drifting in various directions. If you find the helicopter
constantly drifts without any directional control input, it will be best to land
the model before making any adjustments to the trim settings. Additional
details regarding the location and function of the trim buttons can be
found in the Understanding the Primary Flight Controls section of this
manual.
If the nose of the helicopter is drifting to the left or right, you will need to
adjust the rudder trim.
If the helicopter is drifting forward or backward, you will need to adjust the
elevator trim.
If the helicopter is drifting to the left or right, you will need to adjust the
aileron trim.
Continue to make trim adjustments until the helicopter can hover at a low
altitude with very little drifting and directional control input. If the Blade
mCX is your first helicopter model, it may be best to have the help of an
experienced helicopter pilot to trim the model for you before making your
first flight.
25
• Once you have the Blade mCX properly trimmed and maintain a stable
low-level hover, practice using the rudder, elevator and aileron controls to
get a feel for how the helicopter responds to control inputs. Remember to
keep the control inputs as minimal as possible to prevent over-controlling
the helicopter, especially when in hover.

After becoming comfortable with hovering the Blade mCX at low levels of
altitude just a few inches off the ground, you can transition to hovering
and flying the helicopter at higher altitudes of approximately three to four
feet. At these higher altitudes you will be able to get a feel for the flight
characteristics of the Blade mCX when it is flying out of “ground effect.”
• If at any time during flight you feel like the helicopter is drifting out of
control, simply release all of the controls except for throttle. You will need
to use the throttle to maintain altitude, but due to the inherent stability
of the coaxial, counter-rotating blade design, the Blade mCX will simply
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.
• IN THE UNFORTUNATE EVENT OF A CRASH OR ROTOR BLADE
STRIKE, NO MATTER HOW MINOR OR MAJOR, YOU MUST LOWER
THE THROTTLE STICK AND TRIM TO THEIR LOWEST POSSIBLE
POSITIONS AS QUICKLY AS POSSIBLE TO PREVENT DAMAGE TO
THE ESCS OF THE 5-IN-1 UNIT.
Failure to lower the throttle stick and trim to the lowest possible positions
in the event of a crash could result in damage to the ESCs in the 5-in-1 unit,
which may require replacement of the 5-in-1 unit.
