Futaba R2104GF Compact 4-Channel FHSS Receiver  [R2104GF]

Compact FHSS 4-Channel Receiver for Tight Builds

The Futaba R2104GF is a small 4-channel receiver using FHSS 2.4GHz communication, built to act as a reliable link between a compatible Futaba transmitter and on-board servos or ESCs. It provides dedicated channel outputs for steering, throttle, and basic auxiliary functions on compact electric models.

Its reduced footprint makes installation straightforward in cramped chassis areas where clearance and wiring routes are limited. For best results, route the antenna clear of high-current motor and ESC wiring, secure the unit with double-sided foam or low-profile velcro, and confirm binding with the transmitter prior to completing assembly.

During setup the receiver serves as a stable channel source while you set end points, dual-rate, and servo travel from your transmitter. The R2104GF's four channels cover typical servo and ESC needs without extra modules, and FHSS operation helps preserve link stability in everyday RC environments.

As a space-conscious FHSS receiver, the Futaba R2104GF is well suited to projects requiring a dependable four-channel link in confined installations, simplifying tuning and basic setup workflows.
