FHSS 2.4GHz 4CH Receiver R2104GF by Futaba  [R2104GF]

Miniature 4CH FHSS Receiver for Small Models

The Futaba R2104GF is a 4-channel receiver engineered for FHSS operation at 2.4GHz, intended to provide a simple, dependable radio link for radio-controlled models. It functions as the bridge between a Futaba transmitter and on-board control devices, supplying channels for steering, throttle and basic auxiliary control.

The small form factor supports neat installations where chassis packing is tight and wiring clearance is limited. When installing, keep the antenna away from heavy current cables, fasten the receiver with light foam tape or velcro, and complete the transmitter binding process before finishing the build.

Use the receiver as the stable input source while you configure travel limits and rates from your transmitter. With four channels the R2104GF handles common servo and ESC setups without expansion, and its FHSS link helps sustain signal integrity in typical model operating conditions.

With a compact footprint and standard four-channel layout, the Futaba R2104GF is a practical receiver choice for compact electric models where space and weight are at a premium.
