· Adopts a 2-axis nonorthogonal mechanical stabilization structure and is able to carry a payload equipment at a maximum weight of 40g.
· Thanks to the high-torque motors with IMU temperature control and carrier AHRS fusion, the C-40D provides a stabilization accuracy at ±0.05°.
· With the Headtracker, the C-40D provides an immersive highquality first-person control experience.
· Supports Headtracker, UART (private protocol & MAVLink), S.BUS, CRSF and PWM control.
· Can be mounted onto multiple carriers, whether downward or upward.
· 7.4~26.4 VDC wide voltage input.
