Buy KST A08 V6.0 precision micro servo for your FPV drone and racing gliders!

Give your actuators exceptional precision and performance in a compact package. The KST A08 V6.0 servo is designed for high-performance models such as DLG and F5K gliders, but is also ideal for controlling light weight drop systems and yaw systems on FPV drones .

Featuring an innovative coreless motor and steel gearbox, this servo offers smooth operation and outstanding force while weighing just 7 grams. This is a significant upgrade over previous models, offering improved accuracy and reliability .

• Premium Coreless motor. Provides 20% faster response than traditional motors, ensuring instant response to commands .

• High torque. Develops force up to 3.2 kg/cm at a voltage of 8.4V for confident control of mechanisms.

• Lightning speed. Just 0.09 seconds at 60 degrees at 8.4V provides ideal dynamics .

• Maximum reliability. Steel gears and aluminum housing ensure durability, rigidity and efficient heat dissipation .

• Programmable functions. Supports fine-tuning of parameters through the KST-Tool programmer, including setting the zero point and speed.

Operating principle and design

KST A08 V6.0 is a digital HV micro servo drive based on advanced coreless motor technology. Unlike traditional iron-core motors, a coreless motor has significantly lower rotor inertia. This allows it to accelerate and decelerate almost instantly, providing exceptional positioning accuracy and fast response . Digital technology provides higher angular resolution and faster, more accurate position holding compared to analog servos .

The durable aluminum alloy body not only protects internal components, but also effectively dissipates heat to maintain stable performance under long-term use. The hardened steel gearbox and compact design ensure shock resistance and durability . Programmability via KST-Tool Card #1/ #5 allows experienced users to fine-tune the servo for the perfect installation .

Specifications and Compatibility

This servo is ideal for use as a drive for load drop systems on lightweight FPV drones, for controlling miniature gimbals, as well as for DLG/F3K/F5K gliders and indoor model aircraft . Thanks to its programming and high precision, it is an excellent choice for projects where every gram and fraction of a second matters.
