Features: Integrated design of 6-axis (3 gyro + 3 acc); MEMS sensor for self-stability and self-balance. 4 flight modes: Normal Stabilization, 3D Attitude Locking, Self-balance and Gyro Deactivated Modes. 3 control behaviors: stable, normal and sport modes. Separate dual aileron and elevator with dual input supported. Easy-to-use program card which supports both Simplified Chinese and English. Independent gyro gain adjustment and gyro ratio selection for each flight mode. Separate adjustments of servo travel limit to both sides of neutral. Mixing functions of delta-wing (flying-wing) and v-tail. More advanced configurations can be customized such as servo operating frequency, gyro response rate, gyro switch, level offset, stick centering and stick dead band. Specifications: Gyroscope: +/- 2000 dps Accelerometer: ±4g Input Voltage: DC5V~9V Supported Servo Type: 1520s analog and digital servo Operating Temperature: -40'F~85'F
