Product Characteristic:
1.The single propeller design, built-in gyro are used to increase the helicopter stability and operability. It is the best choice for beginner.
2.Aluminum fuselage design and innovative appearance make the helicopter full of attraction.
3.By using the 2.4G auto connection technology, users can operate many helicopters simultaneously with high stability.
4.Micro-computer controlled LCD remote controller brings more operation pleasure for players. By adjusting the parameter, users can randomly regulate the helicopter left/right turning speed, left/right sideways fly speed and the speed of moving forward/backward.
5.Forward/backward and sideways fly are controlled by swashplate, the helicopter is strong enough for outdoor free flight. 
6.Omnibearing remote control: go up and down, go forward and backward, turn left and right, fly left and right sideways.
7.Full proportional servo control system: full proportional servo control system provides driving force for the flight, the parameter of the servo can be adjusted which enables the helicopter to well perform the actions of moving forward, backward, flying sideways, ect.
8.Searchlight: the colorful searchlight not only makes night flight easier, but makes the helicopter look more attractive.
9.Gyroscopic stabilizer: The AVCS gyro has the strong ability to correct helicopter momentary large defluxion, and also the small, continuous defluxion.
10.Triple protection: to protect the helicopter and prevent any risk caused by the stuck of the main rotor, the main rotors will stop rotating and the helicopter will cut off electricity automatically which provides more safety to users.
