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.
