• 4-pole brushless motor. Provides high efficiency, smooth running and incredible power.

• Colossal torque. Develops force up to 82 kg/cm at 8.4V for confident control of heavy machinery.

• Lightning speed. Just 0.11 seconds per 60 degrees at 8.4V guarantees instant response to commands.

• Maximum reliability. CNC aluminum body and hardened steel gears provide durability and rigidity to the design.

• Protection from external influences. IP65 waterproofing allows the servo to be used in wet weather and when planting in wet grass.

Operating principle and design features

This is a digital HV servo drive designed specifically for large scale model aircraft and industrial applications. It is powered by an innovative 4-pole brushless motor, which provides significantly faster response and efficiency compared to traditional motors. The high-precision digital controller processes the signal at a frequency of 333 Hz (1520 µs), ensuring exceptional precision and smooth movement without jerking.

The durable, CNC-machined, aircraft-grade aluminum casing not only adds rigidity to the structure, but also effectively dissipates heat, maintaining stable performance under long-term use. The hardened steel gearbox and two precision ball bearings minimize backlash and ensure durability even under heavy use . Testing confirms that the servo drive provides fast and predictable positioning with minimal backlash and stable thermal performance during continuous operation .

Specifications and Compatibility

The servo is ideal for use in large FPV drones, cargo drop systems, gimbal rotating mechanisms, as well as for controlling the control surfaces of large model aircraft and industrial applications . High build quality and premium components ensure stable performance and durability in the harshest operating conditions.
