Futaba S-H700 S.Bus2 Hv Brushless Heli Cyclic Servo


SKU: 01102312-3 Category:


The Futaba S-H700 S.Bus2 HV Brushless Heli Cyclic Servo is engineered to deliver unparalleled performance and reliability for high-demand helicopter applications. Designed specifically for cyclic control on helicopter rotor systems, this servo combines advanced brushless motor technology, high-voltage S.Bus2 compatibility, and precision engineering to provide precise, responsive, and consistent control over your helicopter’s flight dynamics.

Key Features:

  1. Brushless Motor Technology: The S-H700 servo features a brushless motor design that offers several advantages over traditional brushed motors, including higher efficiency, increased power output, smoother operation, and longer service life. By eliminating the brushes and commutator, brushless motors produce less heat and friction, resulting in improved performance and durability, even under extreme flight conditions.
  2. High-Voltage Compatibility: With support for high-voltage operation (HV), this servo is capable of operating at higher input voltages (up to 8.4V), allowing for increased torque output and faster response times compared to standard-voltage servos. The high-voltage compatibility ensures consistent performance throughout the entire flight, maintaining precise control over the helicopter’s cyclic movements for smooth and predictable flight characteristics.
  3. S.Bus2 Communication Protocol: Utilizing Futaba’s S.Bus2 communication protocol, the S-H700 servo offers enhanced flexibility, reliability, and ease of setup. S.Bus2 allows for digital data transmission between the servo and the receiver, enabling precise control over servo functions, such as position, speed, and torque. Additionally, S.Bus2 simplifies wiring and reduces clutter in your helicopter’s setup, making installation and maintenance hassle-free.
  4. Narrow Design: The S-H700 servo features a compact and lightweight design, making it ideal for applications where space is limited, such as helicopter cyclic control. Its narrow profile allows for easy integration into tight spaces within the helicopter’s airframe, while still providing ample torque and speed for responsive control over the rotor blades.
  5. High-Speed Operation: Equipped with a high-speed brushless motor, the S-H700 servo delivers rapid response times and precise movement control, ensuring crisp and accurate cyclic inputs during aggressive maneuvers, such as fast forward flight, aerobatics, and 3D flying. The servo’s high-speed performance enables quick adjustments to the helicopter’s attitude and orientation, enhancing pilot confidence and overall flight stability.
