BONUS: Receive a 950mah battery for longer running time in addition to the regular battery AND free shipping! Features Coaxial, counter-rotating rotor blades that make hovering easy for first-time pilots Flight ready—no assembly required Test flown at the factory to ensure proper setup out of the box Interference-free 5-channel E-flite transmitter with built-in Spektrum 2.4GHz DSM technology Advanced 4-in-1 control unit including 2.4GHz DSM 6-channel receiver, main motor ESCs, mixer and gyro Two feather-light S60 Super Sub-Micro Servos—just 6.0 grams each 2-cell 7.4V 800mAh Li-Po battery pack with Charge Protection Circuitry 2-3 Cell DC Li-Po Balancing Charger and AC Adapter Most parts compatible with the Blade CX Overview The Blade CX2 takes the excitement and beginner-friendly flight stability of the original Blade CX and adds Spektrum 2.4GHz DSM radio control that lets you fly anywhere, anytime without ever having to worry about interference. It's the first ready-to-fly RC aircraft of any kind to come with this extraordinary technology built in. In addition, the 4-in-1 control unit has been updated with improved gyro and tail control that gives the Blade CX2 even better tail response while minimizing drift. Two feather-light S60 Super Sub-Micro Servos provide powerful, precise cyclic control. Topping it all off is an aggressive new body design that looks fantastic in flight and is unlike anything else out there. When it comes to micro heli fun everyone can enjoy, you simply can't beat the value and performance of the Blade CX2. The Blade CX2's coaxial, counter-rotating blades cancel out the rotational torque that makes hovering a conventional heli so diffcult. Instead of a tail rotor, the Blade CX2 uses differential rotor speed for tail control so the inherent stability of the counter-rotating blades is preserved in all phases of flight, making this a heli just about any first-time pilot can enjoy. No assembly is needed and there is nothing left to buy. In addition to the 2.4GHz DSM 5-channel transmitter and 4 “AA” batteries, the Blade CX2 also includes a rechargeable 2-cell 7.4V 800mAh Li-Po battery pack with Charge Protection Circuitry, DC Li-Po Balancing Charger, AC charger adapter and a step-by-step instructional VCD that helps ensure your first flight is a successful one. E-flite also offers a number of aluminum option parts for the Blade CX2. The Blade CX2 is the first ready-to-fly aircraft of any kind to come with advanced 2.4GHz DSM radio control technology built in. With DSM you never have to worry about interference from other RC users, nearby 2.4GHz devices or commercial transmission towers. There is no tuning and no channels to select. Just power up and fly. The optional Training Gear Set (EFLH1205; sold separately) makes learning to fly the Blade CX2 even easier than it already is by adding more stability and helping to prevent blade strikes.
