Features:<\/b><\/p>\n

1. According to the scale reduction of J3-CUB, highly simulated machine, using super-strong and super-tough EPP material, electronic stabilization system, more accurate hand feeling, more stable flight, optimized structure to reduce the probability of damage.<\/p>\n

2. The propeller is designed based on the principle of aerodynamics to provide strong power and body self-stability. It has high efficiency, power saving and long flight time. The blades are made of ABS+PC composite material, which has high strength, good toughness, impact resistance, no deformation, and durability.<\/p>\n

3. Using 0720 coreless motors, 3 motors drive a main propeller, which reflects the characteristics of large torque, sufficient power and high efficiency. The special high-temperature resistant magnetic steel can withstand 150 degrees of high temperature without damage.<\/p>\n

<\/p>\n

4. Using high-efficiency 2g digital servo, high torque, fast response, high precision, accurate centering, response speed 60\u00b0\/0.08ms, so that the aircraft can fly accurately, feel good, and last longer.<\/p>\n

5. Adopt 6-axis gyroscope. It has a stable, fast and accurate flight attitude, which is especially suitable for beginners to fly.<\/p>\n

6. Adopt 2.4GHZ communication protocol, expandable sat. receiver, support DSMX DSM2 PPM S-BUS standard.<\/p>\n

<\/p>\n

7. The rear three-point landing gear layout integrates image reality and application, which is conducive to take-off and landing. The super tough EVA tires assist in take-off and landing. It has high strength, high toughness, non-deformation and impact resistance, ensuring the durability and safety of aircraft taking off and landing.<\/p>\n

<\/p>\n

8. Standard 3-channel remote control, with LCD display, power prompt, large and small operation rudder amount, and optimized joystick output, making the operation more precise.<\/p>\n

<\/p>\n

9. Professional customized high-rate lithium polymer 3.7V 500mah 25C battery with high discharge rate and long service life. The flight time is about 20 minutes, and the normal use can reach 500+ cycles.<\/p>\n

<\/p>\n

10. Dedicated USB lithium battery charger, with charge balance and charge stabilization function, can charge 2 sets of batteries at a time.<\/p>\n
