Product overview
The AXR 8860 MG-D from Zhuhai SV Tech Co., Ltd. is a standard servo for model steering, control surfaces and mechanical actuation. Its configuration combines a coreless motor, stainless steel gears and two bearings in a 40 × 20 × 40.4 mm body weighing 80 g. A 300 mm cable provides connection reach. Integration requires matching the supply, signal pulse widths, mounting holes and servo-arm connection, with the final mounting drawing and interface version established before mount fabrication.
The servo accepts 4.8–8.4 V and uses PWM control at 333 Hz. At 8.4 V, its stall torque is 70 kg·cm, no-load speed is 0.11 s/60°, and stall current is 8 A; rated torque is 22 kg·cm. Continuous-load sizing must consider rated torque and duty cycle. The 1520 µs reference pulse differs from the 1500 µs positional midpoint, so neutral and usable travel depend on the controller and delivered version. Initial setup should use reduced or removed load, with supply margin for transient current.
