Functional Description 1> According to J3-CUP scale reduction, highly simulated machine, using super-strong and super-tough EPP material, electronic stabilization system, more accurate feel, more stable flight, and optimized structure to reduce the probability of damage. 2>The propeller is designed with aerodynamic principles, providing strong power and self-stability of the body. It has high efficiency, power saving and long flight time. The blade is made of ABS+PC composite material, which has high strength, good toughness, impact resistance, no deformation and durable. 3> Using 0720 hollow cup motor, 3 motors drive one main propeller, which reflects the characteristics of large torque, sufficient power and high efficiency. The special high temperature resistant magnetic steel can withstand high temperature of 150 degrees without damage. 4> Using high-efficiency 2g digital steering gear, high torque, fast response, high precision, and accurate return to the center, the response speed is 60/0.08ms, which makes the aircraft fly accurately, feel good, and last longer. 5> Using 6-axis gyroscope. It has a stable, fast and precise flight attitude, especially suitable for beginners to fly. 6> Adopt 2.4GHZ communication protocol, expandable satellite receiver Support DSMX DSM2 PPM S-BUS standard. 7> The layout of the rear three-point landing gear, which integrates the image and the real application, is conducive to take-off and landing. The super-tough EVA material tires assist in take-off and landing. It has the characteristics of high strength, high toughness, non-deformation and impact resistance, ensuring the durability and safety of aircraft take-off and landing. sex. 8> Standard 4-channel remote control, with LCD screen, power prompt, large and small operation rudder, and optimized joystick output for more precise operation. 9> Professional customized high rate lithium polymer 3.7V 500mah 20C battery, high discharge rate, long service life, flight time of about 20 minutes, normal use can reach 500+ cycles. 10> Dedicated USB lithium battery charger, with charge balance and charge stability function, can charge 2 sets of batteries at a time.
