- 505mm Wing span. Reduced according to J3-CUP ratio, height simulator, use of super strong and super tough EPP material, electronic stability enhancement system, more precise hand feel, more stable flight, optimized structure to reduce damage.
- The propeller is designed using aerodynamic principles to provide strong power and stability. It has high efficiency, low power consumption, and long flight time. The blade is made of ABS+PC composite material, which has high strength, toughness, impact resistance, deformation resistance, and durability.
- Using the 0720 hollow cup motor, the three motors drive one main propeller, reflecting the characteristics of high torque, power, and efficiency. The specially designed high-temperature resistant magnetic steel can withstand high temperatures of 150 degrees without damage.
- Using an efficient 2g digital servo, it has the characteristics of high torque response, fast accuracy, high return accuracy, and a response speed of 60 °/0.08ms, making the aircraft precise in flight, with good tactile feel and longer lifespan.
- Using a 6-axis gyroscope which has a stable, fast, and accurate flight attitude, especially suitable for beginners in flight.
- Adopting the 2.4GHZ communication protocol, the satellite receiver can be expanded to support the DSMX DSM2 PPM S-SUS system.
- The layout of the rear three point landing gear integrates visual and practical applications, making it easy for takeoff and landing. Super tough EVA tyres are used to assist in take-off and landing, with high strength, toughness, unchanged shape, and impact resistance, ensuring the durability and safety of the aircraft.
- Standard 4-channel remote control with LCD display for battery level indication and optimized joystick output for more precise movements.
- Professional customized high rate lithium polymer 3.7V 500mah 25C battery with high discharge rate, long service life, and flight time of about 20 minutes. Normal use can reach 500+cycles.
- Dedicated USB lithium battery charger with charging balance and stable charging function.
