Futaba R2104GF 4-Channel 2.4GHz FHSS Receiver  [R2104GF]

Compact 4-Channel FHSS Receiver

The Futaba R2104GF is a compact 4-channel receiver built around FHSS 2.4GHz operation, intended as a straightforward link component for radio-controlled models. It serves as the interface between a transmitter and on-board control devices, providing channel outputs for steering and throttle control on small electric models and for general servo management.

Installation is simplified by the receiver's small footprint, allowing placement in tight chassis spaces where routing and clearance are constrained. When fitting the unit, position the antenna wire away from high-current wiring to reduce noise, secure the receiver with double-sided foam or small velcro patches, and confirm transmitter binding before final assembly.

In tuning and setup, use the receiver as a stable channel source while you set end points and dual-rate on your transmitter. The R2104GF's 4 channels make it suitable for basic servo and ESC arrangements without requiring expansion modules, and its FHSS link helps maintain a robust signal in typical RC model environments.

As a compact FHSS receiver, the Futaba R2104GF fits projects where space is limited and a reliable four-channel link is required, making it a practical choice for basic electric RC model installations and straightforward tuning workflows.
