Battery Warnings and Guidelines

The Battery Charger (EFLC1000) included with the Blade mSR 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 AN 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:

 For AC operation, 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 become damaged and may no longer accept a 

charge. The mSR X 4-in-1 control unit protects the flight battery from over-discharge using Low Voltage Cutoff 

(LVC). Before the battery charge decreases too much, LVC reduces power supplied to the motor. Power to the motor 

decreases and the LED on the 4-in-1 control unit blinks, showing some battery power is reserved for flight control 

and safe landing.
When the motor power decreases, 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 battery charge does not go below 3V.

NOTICE:

 Repeated flying to LVC will damage the battery. 

AS3X Flybarless Helicopter Technology

The Blade mSR X features on-board AS3X flybarless technology, first designed for the Blade mCP X. AS3X  

technology combines 3-axis gyro stabilization with a new flybarless fixed-pitch rotor head, resulting in less drag, 

fewer parts and increased performance. 
The  AS3X technology also improves tracking, stability and cyclic response for intermediate and advanced pilots. 

However, the AS3X flybarless system is not a flying aid for beginners. 

Installing the Transmitter Batteries

Install AA batteries into transmitter, noting polarity. Replace 

the transmitter batteries when the power LED flashes and the 

transmitter beeps.
