Storage Box for Radiomaster 4in1 + JR Adapter

This purpose-built storage and transport box securely holds the Radiomaster 4-in-1 module together with its JR bay adapter. Ideal for all users of TX16s or TX15 ELRS transmitters, that use the optional 4in1 module.

It’s designed for pilots who routinely swap modules or want a safe, organized way to protect their gear in the field, in a backpack, or on the workbench.

The bottom tray cradles the module+adapter assembly and the antenna in dedicated pockets. A spring-loaded push-click retention system keeps everything firmly locked in place, yet releases effortlessly with a natural finger press.

The protective cover snaps on using flexible latches and matching notches, providing a secure closure without requiring force. Finger cutouts make the lid easy to remove.

Everything is optimized to be

• rugged enough for transport
• precisely sized for the 4-in-1 + JR adapter combo
• simple to open and close

A tidy, reliable way to keep this delicate transmitter module set together and protected.
