13-1/2" rotor span, 7-1/4" high, 17" long, flying weight 8-1/2 oz. The Coaxial Comanche is complete and ready to fly and includes a 4 channel 72 MHz FM transmitter, a 4-in-one mixer/controller (electronic gyro, mixer, motor controller, receiver), two motors, two servos, 7.4V 800 mAh Lithium battery and Lithium battery charger. Charge the flight battery, install the included 8 AA batteries in the transmitter and fly. Easy enough for a beginner but will bring a smile to even a seasoned chopper pilot. The 72 MHz radio, motors and servos are hobby quality products that will provide many hours of service. Durable design bounces rather than breaks in most crashes; comes with a complete spare set of main blades and we stock spare parts. Has wheels for a realistic look and for easy landings and take-offs. Tail fan adds realism but is non-functional; canopy is tinted to hide electronics.
