Targethobby Flysky FGr4s V2 Receiver (2-pack) — AFHDS 3, 4-Channel for Noble NB4/Noble Pro

Overview

The Targethobby Flysky FGr4s V2 Receiver is a compact, four-channel AFHDS 3 unit designed to work with Flysky Noble NB4 and Noble Pro transmitters. This pack includes two ultra-light receivers, making it easy to outfit multiple models or add redundancy to your existing setup without adding bulk. Despite its small footprint, the FGr4s V2 delivers responsive communication and straightforward binding, so you can focus on your ride or race rather than fiddling with hardware.

Whether you’re toggling throttle on a fast car, steering a nimble boat, or exploring new control ideas, this receiver is built to slot into tight spots and stay out of the way. Its integrated design helps reduce wiring and weight, which matters when every gram counts on a small RC model.

What makes it stand out

• AFHDS 3 third-generation digital system for modern Flysky ecosystems
• Two-way transmission for bidirectional data between transmitter and receiver
• Multiple data outputs: PPM, i-BUS, S.BUS, and PWM to fit different controller setups

What’s in the package: 2 × Flysky FGr4s V2 receivers, ready to bind with compatible Noble NB4 or Noble Pro transmitters. Ultra-small and light, these units help conserve space and reduce weight on compact builds.

Practical use cases

Install one receiver in a high-performance RC car to keep steering and throttle inputs crisp, while a second unit can be deployed in a boat for independent signaling or as a spare link if you’re testing new configurations. The built-in antenna minimizes wiring, and the compact size makes it easier to tuck the module away in crowded compartments. With PPM, i-BUS, S.BUS, and PWM outputs, you can tailor compatibility to your existing controller ecosystem and future-proof your setup with AFHDS 3 features.

Benefits in context

• Smaller footprint and lighter weight help maintain balance on small vehicles
• Two-way transmission can improve responsiveness and diagnostic feedback
• Multiple output formats enable flexible integration with different receivers and controllers
• Two-pack provides a convenient solution for dual-model setups or backup
