Alaohu FS-GT3B 3-Channel RC Transmitter with FS-GR3E Receiver – 2.4GHz AFHDS Sky System

Overview of the Alaohu FS-GT3B 3-Channel System

The Alaohu FS-GT3B is a compact gun-style transmitter designed for RC cars and boats, pairing with the FS-GR3E receiver to deliver a reliable 2.4GHz AFHDS connection. Its clean interface, backlit display, and external antenna are built for on-the-go setups and field tuning. The kit emphasizes efficient power use and a straightforward binding workflow, making it a practical choice for hobbyists who value clarity over complexity.

How it works

This 3-channel system uses the AFHDS digital protocol to manage steering, throttle, and auxiliary functions. The combination offers a ground range of roughly 100–200 meters under typical conditions, with a 1024-channel resolution that supports precise control inputs. An HTM blue film negative display with a white LCD backlight keeps status information visible in bright sun or dusk conditions. An external single antenna helps maintain signal visibility during fast, dynamic maneuvers.

• 2.4GHz AFHDS for anti-interference capabilities and lower power use
• 3 channels suitable for RC Car or RC Boat applications
• DSC interface can output PPM connection simulator dongle (cable not included)

Key features and practical use cases

The transmitter features a large, legible display, a robust control grip, and a modern backlight for field work. The 2.4GHz AFHDS system supports stable operation with compatible receivers, and the PPM output option via DSC makes it easier to integrate with compatible rigs or simulators. The system has a rated 100–200m range on the ground, depending on terrain and interference, which suits casual track sessions or water-based runs.

Real-life scenarios include quick setup for a fresh RC car sprint, or a boat run along a pond where clear feedback is essential. The device’s low power consumption and straightforward diagnostics help keep operations smooth, while the compatibility note reminds users to pair only AFHDS receivers such as FS-GR3E or FS-GR3F (AFHDS_2A is not supported).
