Overview

The Reefs RC SUB Micro 3.52kg SMART Servo/Winch is a powerful and versatile micro servo designed for various RC applications, including winching. Its high torque and speed make it suitable for demanding tasks, while its compact size allows for installation in tight spaces. The servo boasts a robust construction, featuring durable metal gears, a CNC machined aluminium casing, and sealed bearings for protection against the elements. The integrated SMART chip technology allows for custom programming and fine-tuning using the optional REEFS LINK programming tool.

Operating within a voltage range of 4.8V to 8.4V, this servo delivers impressive performance. At 8.4V, it achieves a torque of 3.52kg-cm (49oz-in) and a speed of 0.05 sec/60°. The 20Tφ4.0mm spline ensures compatibility with a wide range of servo horns and accessories. While a BEC is not strictly required, it is recommended for maximum performance. For multi-use installations, 49SubMicro Tabs are recommended (sold separately). This servo can also be used as a winch with the appropriate spool kit.
