Product overview A 7.1 multifunction main board designed for 1/16 scale RC tanks. This board is compatible with radio controller versions 7.1 and 7.0 and serves as a direct replacement to restore or upgrade core tank control functions. Key benefits Restores full tank control: Replaces a malfunctioning main board to bring back remote steering, drive, and auxiliary functions. Compatibility focused: Built to work with 1/16 RC tank models that use 7.1 or 7.0 radio controllers, reducing integration steps. Simplifies repairs and upgrades: Swapin replacement helps avoid costly purchases of a model when electronics fail. Reliable operation: Designed for consistent signal processing and multifunction coordination for common tank behaviors. Main attributes Function: Multifunction main board for centralized control of a model tank s electronics and peripherals. Compatibility: Works with 1/16 scale RC tank models using radio controller versions 7.1 and 7.0. Fit: Sized for 1/16 tank installations to align with existing mounting points and wiring harnesses. Performance: Handles command input from compatible controllers and routes signals to motors, servos, and attached modules. Installation and use Direct replacement: Designed for straightforward removal of the old board and installation of the board with existing connectors and mounting. Diagnostic aid: Use when the original board shows intermittent control, unresponsive channels, or fails to power peripheral systems. Maintenance tip: Inspect connectors and wiring while replacing the board to ensure performance and longevity. Typical applications a hobby 1/16 RC tank after a control board failure to restore full remote operation. Upgrade or an older board to ensure compatibility with a 7.1 or 7.0 radio controller being used for competitions or rehearsed runs. Use in workshop projects or custom builds where a multifunction control board is required for drive and turret systems. Why choose this board This main board provides a practical, compatibilityoriented solution for maintaining or upgrading 1/16 scale RC tanks. It focuses on restoring reliable control and simplifying the replacement process so models can to operation quickly.
