Frequently asked questions
How much does the AX-40D weigh?
AX-40D weighs 38g. Its dimensions are 64 x 59 x 36.2mm, so check both mass and envelope against your mount.
What power does the AX-40D need?
AX-40D accepts 7.4~26.4VDC. Power draw is 2W (Static) / 12W (Stall). Confirm your platform can supply this continuously, not just at peak.
How is the AX-40D stabilized?
AX-40D uses 2-axis Mechanical Stabilization. Published angular accuracy is ±0.05°.
What is the AX-40D controllable range?
Pitch: ±110°, Roll: ±45°. This is the mechanical travel available to the operator or autopilot.
How do you control the AX-40D?
AX-40D exposes Headtracker / UART (private protocol & MAVLink) / S.BUS / CRSF / PWM. Match this to your flight controller or ground station before ordering.
