Features: 
1>Adopting flybarless design, canceling the traditional balance bar structure, electronic stabilization system, more accurate hand feeling, more stable flight, optimized structure to reduce the probability of damage. 
2>The propeller is designed with aerodynamic principles to provide strong power and body self-stability. 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 durability. 
3> Use 050 strong magnetic core motor, with large torque, sufficient power and high efficiency. The special high-temperature resistant magnetic steel can withstand high temperature of 150 degrees without damage, and the 6061 hard aluminum radiator is installed to further improve the service life. 
4> The tail-locking motor uses a special 8520 coreless motor, which has the characteristics of high temperature resistance,stable tail-locking, and it is not easy to be damaged after long-term work. 
5> Use high-efficiency 4.3g digital steering gear, high torque, high precision. With the characteristics of accurate centering and response speed of 60°/0.05ms, the aircraft can fly accurately, with good hand feeling and longer life. 
6> Adopt 6-axis gyroscope. It has a stable, fast and accurate flight attitude, especially suitable for beginners to fly. 
7> Adopt the air pressure height-fixing module, integrated algorithm, limit the climb and descent speed, make it easier for beginners to grasp, greatly reduce the probability of aircraft damage. 
8> Landing gear The main frame is made of PA66+GF (nylon + glass fiber) composite material, which has high strength, high toughness, non-deformation and impact resistance, ensuring the accuracy and durability of the whole machine. 
9> The case is made of PET blister material with increased thickness and toughness, which has good elasticity and toughness and is not easy to crash. 
10> Standard 4-channel remote control, with LCD display, power prompt, large and small operation rudder amount, and optimized joystick output, making the operation more precise. 
11> Professional customized high-rate lithium polymer 3.7V 700mah 20C battery with high discharge rate and long service life. The flight time is about 20 minutes, and the normal use can reach 500+ cycles. 
11> Dedicated USB 7.4V lithium battery dedicated charger, with charge balance and charge stability function.
