This RC boat shaft support kit includes a 4mm flexible shaft assembly with brass tube, Teflon liner, and a 70mm strut mount, designed for high-speed electric model boats. The complete set provides reliable power transmission and smooth operation for custom builds and upgrades.

The flexible shaft measures 350mm in length and includes a 75mm hardened shaft head with 10mm thread, available in both CW and CCW configurations. The brass tube (300mm) and Teflon liner (300mm) reduce friction and wear, ensuring durability and efficiency during extended use.

The 4mm strut support (70mm length × 29mm width × 31mm height) is made of durable metal and comes with essential components including thrust washer, prop shaft coupler, and bullet-style nut for secure propeller mounting.

Ideal for O-class boats, shrimp boats, and other RC hull types, this shaft system offers precision alignment, reduced vibration, and reliable performance for hobbyists and competitive RC boat racing.
