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.

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.

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.

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

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

6. Adopt 2.4GHZ communication protocol, expandable sat. receiver, support DSMX DSM2 PPM S-BUS standard.

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.

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.

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.

10. Dedicated USB lithium battery charger, with charge balance and charge stabilization function, can charge 2 sets of batteries at a time.
