Introduction
As you are about to see, the Blade mCP X truly is an ultra micro heli experience unlike any other. Its advanced flybarless design reduces drag on the rotorhead and significantly boosts cyclic control response. This, combined with its
exceptionally lightweight airframe, delivers a level of power and responsiveness that eclipses that of any ultra micro
heli you have flown before.
Inverted flight, loops, flips, rolls, funnels, hurricanes – the mCP X can do it all, indoors or out, with power to spare. If
you’re transitioning from a basic CCPM or fixed-pitched heli, you’ll find the mCP X is a great way to get used to flying
more agile CCPM helis without having to invest a lot in expensive equipment or repairs.
Before you take the first flight, though, please take time to read through this manual and watch the included DVD.
Both contain important pre-flight information as well as useful tips on binding your transmitter that will help ensure
your first flight is a great one.

Battery Warnings and Guidelines

120F/49C
Always use a
charger compatible
with batteries.

Always charge
Batteries away from
flammable materials.

Never leave
charging Batteries
unattended.

Never charge
damaged Batteries.

Never Alter
Batteries.

Never touch or
use hot Batteries.

The Battery Charger (EFLC1006) included with the Blade mCP X has been designed to safely charge the
Li-Po battery.
CAUTION: All instructions and warnings must be followed exactly. Mishandling of Li-Po batteries can result
in a fire, personal injury, and/or property damage.
• By handling, charging or using the included Li-Po battery you assume all risks associated with lithium batteries.
• If at any time the battery begins to balloon or swell, discontinue use immediately. If charging or discharging,
discontinue and disconnect. Continuing to use, charge or discharge a battery that is ballooning or swelling can
result in fire.
• Always store the battery at room temperature in a dry area for best results.
• Always transport or temporarily store the battery in a temperature range of 40–120º F. Do not store battery or
model in a car or direct sunlight. If stored in a hot car, the battery can be damaged or even catch fire.
• NEVER USE A Ni-Cd OR Ni-MH CHARGER. Failure to charge the battery with a compatible charger may cause fire
resulting in personal injury and/or property damage.
• Never exceed the recommended charge rate.
• Never discharge Li-Po cells to below 3V under load.
• Never cover warning labels with hook and loop strips.
WARNING: Only use an E-flite 6V power supply with this charger. DO NOT use a 12V power supply or
property damage and injury could occur.

Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V, the battery may be damaged and may no longer accept a charge. The mCP
X 3-in-1 control unit protects the flight battery from over-discharge using Low Voltage Cutoff (LVC). Before the battery
charge decreases too much, LVC removes power supply from the motor. Power to the motor decreases  and the LED on
the 3-in-1 control unit blinks, showing some battery power is reserved for flight control and safe landing.
When the motor power decreases, please land the aircraft immediately and recharge the flight battery.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. Before storage, charge
the Li-Po battery to full capacity. During storage make sure the battery charge does not go below 3V.
NOTICE: Repeated flying to LVC will damage the battery.

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 mCP X 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® DSM®
technology equipped aircraft transmitter to the receiver for proper operation.
NOTICE: Use the Non-Computer Radio binding instructions if you are using a DX4e or DX5e transmitter
with the mCP X BNF.



Binding Procedure for Computer Radios:
1. Disconnect the flight battery from the helicopter.
2. Power off the transmitter and move all switches to the 0 position.
3. Connect the flight battery in the helicopter. The 3-in-1 control unit LED flashes after 5 seconds.
4. Put the transmitter in bind mode while powering on the transmitter.
5. Release the bind button after 2-3 seconds.  The helicopter is bound when the blue LED on the
3-in-1 control unit is solid.
6. Disconnect the flight battery and power the transmitter off.

Note: The throttle will not arm if the transmitter’s throttle control is not put at the lowest position and the stunt
mode switch is not in the 0 position.
If you encounter problems, obey binding instructions and refer to the troubleshooting guide for other
instructions.  If needed, contact the appropriate Horizon Product Support office.
For a list of compatible DSM transmitters, please visit www.bindnfly.com.



Binding Procedure for Non-Computer Radio (DX4e, DX5e)
1. Disconnect the flight battery from the helicopter.
2. Power off the transmitter and move all switches to the 0 position.
3. Connect the flight battery in the helicopter. The 3-in-1 Control unit LED flashes after 5 seconds.
4. Push in on the trainer switch or button while powering on the transmitter.
5. Move the rudder control stick to full left after the transmitter LED lights flash twice.
6. Release the trainer switch button. Continue to hold the rudder control stick to full left until the blue
LED on the 3-in-1 control unit is solid.
7. Release the rudder control stick.
8. Push in on the trainer switch button. The blue LED on the 3-in-1 control unit flashes to confirm the

Throttle Hold
Throttle hold is used to turn off the helicopter motors if the helicopter is out of control, in danger of crashing
or both. Activate throttle hold anytime the helicopter is in danger of crashing to reduce the chance of
damaging the helicopter in a crash. Throttle hold will stop the motor in normal or stunt mode.

Throttle Hold ON (DX4e)
Press the trainer button anytime to turn throttle hold ON after connecting the
battery to the helicopter. The blue LED flashes, indicating throttle hold is ON.

Throttle Hold OFF (DX4e)
1. Make sure the AUX switch is in the OFF position.
2. Lower the throttle stick.
3. Press the trainer button three times within 3 seconds. The blue LED is solid.

Installing the Flight Battery

1. Lower throttle and throttle trim to lowest settings.
2. Power on transmitter.
3. Install flight battery in the battery holder. Connect the battery cable to the 3-in-1 control unit.
NOTICE: Do not allow the helicopter to move until the blue LED on the 3-in-1 control unit is solid.
NOTICE: Always disconnect the Li-Po from the receiver of the aircraft when not flying. Failure to do so will
render the battery unusable.

Consult local laws and ordinances before choosing a location to fly your aircraft. Select a large, open area
away from people and objects. The Blade mCP X can fly indoors in a gymnasium.
CAUTION: Please take a few minutes to familiarize yourself with the Blade mCP X primary controls before
attempting your first flight. The Blade mCP X is more responsive than other Blade micro helicopters, such as
the Blade mSR.  Seek help from an experienced pilot if you are new to collective pitch helicopters.

Takeoff
Increase throttle and allow the helicopter time to increase the rotor head speed.
CAUTION: Do not give any aileron, elevator or rudder commands before takeoff or the helicopter may crash
during takeoff.

Flying
The helicopter lifts off the ground when the rotor head reaches a suitable speed. Establish a low-level hover to
verify proper operation of your helicopter.  You will not need to set any trim; the flybarless design of the mCP X
renders trim unnecessary.
For pilots new to collective pitch helicopters, familiarize yourself with your mCP X in normal mode. Discover the
rates that fit your flying style.
CAUTION: Always fly the helicopter with your back to the sun to prevent loss of flight control.

Landing
Establish a low level hover. Slowly lower the throttle until the helicopter lands.
