Product overview
The Zhuhai SV Tech Co., Ltd. AXR 9492 MG-D is a mini servo for fixed-wing control surfaces and mechanisms with restricted installation space. Its architecture combines a brushless motor, stainless steel gears and two bearings in a 23 × 12 × 26.8 mm body weighing 22.2 g. The hardware configuration includes a 250 mm cable and PWM control at 333 Hz. Integration requires room for the output shaft, mounting holes, connector and servo-arm linkage; increasing arm length reduces the force available at the linkage.
The servo accepts 4.8–8.4 V, with performance specified at four test voltages. At 8.4 V it delivers 13.5 kg·cm stall torque and a no-load speed of 0.062 s/60°, while rated torque is 4 kg·cm at 7.4 V. Stall torque cannot be used as a continuous-load rating. Control setup also requires attention: the reference pulse is 1520 µs, while the angle mapping places center at 1500 µs. Center and usable travel must match the controller and delivered version, with supply capacity reserved for transient current.
