Product overview
The AXR 8482 MG-D is a mini servo for fixed-wing control surfaces and mechanisms with restricted installation space. Its physical configuration combines an iron-core motor, metal gears and two bearings in a 30 × 11.9 × 26.3 mm body weighing 18.3 g, with a 250 mm cable. Installation planning must account for output-shaft location, mounting-hole spacing and connector clearance as well as the external envelope. Servo-arm length also affects selection because increasing the arm length reduces the force available at its end.
The servo accepts 4.8–8.4 V power and PWM control at 333 Hz. At 7.4 V, its rated torque is 2.4 kg·cm, while stall torque is 7.3 kg·cm and no-load speed is 0.059 s/60°. Stall torque cannot serve as a continuous-load rating; duty cycle also matters. The specified 1520 µs reference pulse differs from the 1500 µs position midpoint, so center and usable travel require adjustment to the controller and delivered version. Initial setup calls for unloaded or limited-load movement checks and supply headroom for transient current.

| Load limitation | Stall torque is not a continuous-load rating; continuous-duty selection requires consideration of rated torque and duty cycle. |
| Center position and travel | The 1520 µs reference pulse and 1500 µs position midpoint are both specified; center position and usable travel must be established for the controller and delivered version.Controller and delivered servo version. |
| Mechanical integration constraints | Integration requires allowance for output-shaft position, mounting-hole spacing and connector clearance; longer servo arms reduce available output force. |
