Goolsky Flysky FGR4S V2 Receiver - Compact 4-Channel AFHDS3

In this review of the Goolsky Flysky FGR4S V2 receiver the bottom line is simple: this is a compact, lightweight 4-channel radio receiver best suited for hobbyists who need a reliable AFHDS 3 link for RC car or RC boat projects. The reviewer found the unit easy to bind to compatible Flysky transmitters and appreciated the built-in single antenna design that keeps installation tidy. If the priority is stable connection and minimal size rather than advanced telemetry, the Goolsky FGR4S V2 stands out as a practical replacement or upgrade for small vehicles.

Key Features

• AFHDS 3 system: Provides fast link-up and stable automatic frequency hopping for consistent control in typical RC environments.
• 4 channel output: Supports steering and throttle setups for RC car and RC boat use with straightforward channel mapping.
• Multiple output modes: Offers PWM, PPM and i-bus output options so it fits a range of receivers, servos and flight controllers that accept AFHDS3 signals.
• Built-in single antenna: Keeps the receiver compact and simple to install while providing two-way transmission capability for reliable communication.
• Ultra-small, ultra-light: Saves space and reduces weight inside small hulls and chassis where every gram counts.

Who It's For

The Goolsky Flysky FGR4S V2 is aimed at hobbyists who run Flysky Noble FS-NB4 or PL18 transmitters and need a compact receiver for RC cars or boats. It is ideal for builders replacing bulky receivers or for racers and casual pilots who prioritize a clean installation and reliable AFHDS 3 link.

Those who need advanced telemetry, long-range certified links, or integrated power management should look elsewhere; this receiver focuses on compact size, basic channel control and compatibility with AFHDS3 transmitters rather than expanded telemetry features.

Pros & Cons
