FlySky Introduces its newest 4 channel 2.4GHz system, the FS-i4X.

The Flysky FS-i4X is a beginner-friendly 2.4 GHz radio control transmitter designed for RC aircraft, gliders, boats, and helicopters. It uses Flysky’s AFHDS 2A protocol, which provides stable communication, automatic frequency hopping, and improved resistance to signal interference.

This transmitter typically offers 4 channels, with the possibility of expanding up to 10 channels through modification, making it flexible for a range of RC applications. It includes useful features such as channel reversing and channel mixing, allowing users to adjust control functions for different RC models.

Operating on the 2.4 GHz frequency band, the FS-i4X provides reliable control with a typical range of approximately 500–1500 meters in open environments. The transmitter runs on four AA batteries and is designed with low-power components to reduce energy consumption while maintaining stable performance.
