FrSky Xact Coreless 5500 Series Servo is an original FrSky product from the FrSky servo range family. This page is organized for practical buying decisions, with the fit, RF protocol, channel count, voltage, compatible accessories and installation role presented clearly.
It is suited for servo-controlled RC aircraft, gliders, helicopters, cars or accessory mechanisms. The information focuses on what an end customer needs to choose confidently, without exposing supplier pricing or directing the customer away from RC-MODEL.
Available variants: [03050606] HV5501; [03050607] HV5502
Key Advantages
- The Xact series coreless servos utilize a fully CNC machined aluminum protective case and benefit from metal gears. These high-voltage servos are capable of supporting up to 8.4V and offer both high speed and torque performance. The Xact series servos are available in multiple form factors and configurations to fit many different model types especially where power, reliability, and precision are required.
- These high-quality servos support the FBUS protocol, which allows telemetry data (like real-time current, voltage, temperature, etc.) of Xact servos to be transmitted back to the radio by connecting either FBUS capable receiver or flight controller. The Xact servos offer configurable servo travel (90° / 120° / 180°). Servo travel along with other options are now available to be set via the ETHOS Xact configuration tool or the Freelink app.
- Supports F.Port 2.0 (FBUS) SBUS and PWM protocol
- High durability with metal gear and all-aluminum CNC machined protective case
- Waterproof design gives stronger durability for RC vehicles in wet conditions
- 8.4V high voltage capable operation with good speed performance
