Features and Benefits

• High precision and stability thanks to the digital controller, ensuring correct operation under intense loads and during rapid maneuvers.

• All-metal gears increase wear resistance and extend lifespan compared to plastic counterparts.

• Very fast response — 0.05 sec/60° at 7.4 V makes the DS145MG ideal for helicopter tail control, glider control surfaces, and racing FPV drones.

• Aluminum case provides structural rigidity and efficient heat dissipation, reducing the risk of overheating during intensive flights.

• 2S LiPo support (4.8-7.4 V) allows the servo to be operated without an additional BEC in many configurations, simplifying the electrical circuit and reducing the overall weight of the project.

The KST DS145MG 23G servo is recommended for applications where compactness, low weight, and high speed are important: FPV drones, flying wings, gliders, helicopter models, and other RC aircraft. Thanks to the combination of high speed (0.05 sec/60° at 7.4 V), sufficient torque (4.2 kg·cm at 7.4 V), and reliable mechanical components, the DS145MG provides smooth, precise, and durable control of control surfaces.
