manual completely before proceeding.

First Flight Preparation

• Remove and inspect contents
• Install four of the included AA batteries in the charger
• Begin charging the flight battery
• Install the remaining four AA batteries in the transmitter
• Install the flight battery in the helicopter (once it has been fully charged)
• Test the controls
• Familiarize yourself with the controls
• Find a suitable area for flying

Flying Checklist

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

Battery Warnings and Guidelines

The 1S 3.7V DC Lithium Polymer Battery Charger (PKZ3240) included with the Blade mCX2 has been
specifically designed to safely charge the included 150mAh 3.7V 14C Li-Po battery. You may also use
the E-flite ® Celectra ™ 4-Port Charger (EFLC1004). You must read the following safety instructions
and warnings before handling, charging or using the Li-Po battery.
(RTF ONLY)
CAUTION: Li-Po batteries are significantly more volatile than the alkaline, Ni-Cd or Ni-MH batteries used
in RC applications. 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 you do not agree with these conditions, return your complete Blade mCX2 model in new,
unused condition to the place of purchase immediately.
• You must charge the included Li-Po 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.
• After flight, the battery must be cooled to ambient temperature before charging.
• DO NOT 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.
• 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 40–120º
F. 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 Li-Po flight battery. Discharging the battery too low can cause damage to
the battery resulting in reduced power, duration or failure of the battery entirely.
Li-Po cells should not be discharged to below 3V each under load. In the case of the Li-Po battery used
for the Blade mCX2, do not allow the battery to fall below 3V during flight.
The Blade mCX2'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 reduce power
to the motors (regardless of the power level set with the throttle stick) in order to prevent the voltage
of the battery from dropping below 3V. This power reduction usually requires you to 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 Li-Po
battery resulting in lost power and duration in subsequent flights, 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 may drop below the minimum operating voltage of the receiver and other
electronics.
Also, it is not recommended that you fly to the soft LVC every time you fly. Instead, be aware of the
power level of the battery/helicopter throughout the flight, and if at any time the helicopter begins to
require more throttle than typical to maintain hover or flight, 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.
