THETA THS921A High-Voltage Micro Servo
The THETA THS921A is an upgraded high-end micro servo designed for pilots who demand exceptional precision, torque, and speed in a compact format. Fully high-voltage compatible and engineered with outstanding centering performance, it delivers reliable, crisp control for even the most demanding maneuvers.
This servo is ideal for 450-class helicopters such as the Goblin 380, T-Rex 450, GAUI X3, KDS Chase, and any model with a rotor disc under 420 mm. Its high efficiency and responsiveness also make it a great choice for small to midsize airplanes.
