The Blade®CX4 marks a new era in coaxial performance with several new features to improve your flight experience. You’ll find that with its large size, the CX4 is easy to fly and well suited for novice heli pilots. Hinged
and rubber over-molded main blades offer safer operation, and the landing gear is rubber mounted to help absorb
rough landings, reducing the chance of broken parts from minor incidents. The CX4 sports a modern full body
fuselage, including an LED spotlight and flashing navigation tail light for those low-light missions around the house.
A 3S 800mAh Li-Po battery provides the power, and a DSM2®5-channel transmitter with matching Spektrum™
AR6100e receiver enables you to fly several CX4 helis at the same time without fear of interference. This manual
includes important information you need for successful and safe operation of the CX4, so take some time to read
the following pages before you plug in the battery and go fly.

not damaged e.g., swollen, bent, broken or punctured.
2. Connect the charger to a 12V power source, noting proper polarity.
3. The RED LED flashes.
4. Connect the battery balance lead to the charger. The balance connector is keyed to prevent reverse polarity.
