Receiver Case for Futaba R116FB — Futaba FUAR3131 Receiver Case Set AR3131  [FUAR3131]

Compact receiver case for R116FB installations

The Futaba FUAR3131 receiver case set is an accessory built to house a Futaba R116FB receiver within a model's radio compartment. It supplies a dedicated enclosure that secures the unit and aids neat routing of antenna and power leads while leaving the radio electronics unchanged.

Compatibility is specified for the Futaba R116FB only, and no additional chassis or brand compatibility is implied. To install, seat the receiver in the bay, line up the case mounting points with your model's tie points or tape areas, then secure using standard methods such as double-sided tape or cable ties commonly used in RC workshops.

As an organisational aid, the case keeps wiring tidy and improves accessibility during setup or component swaps; it is intended for protection and convenience rather than altering radio performance.
