Operating principle and design
The KST X12-708 is a digital HV servo drive designed for the most demanding aircraft modeling and drone applications. It is powered by a high-speed brushless motor, which ensures fast start-up and precise positioning. The device operates at 1520 μs / 333 Hz, which guarantees the fast response required for accurate operation of cargo release systems and gimbal control on drones.
The servo drive housing is compact in size and made of durable materials that provide structural rigidity and efficient heat dissipation. All-metal gears ensure durability and resistance to the shock loads inherent in hard drone landings. Due to its low weight (only 20g), this servo is ideal for use in confined spaces of racing drones and light model aircraft.
