Features: FS-i6X automatic self-correcting AFHDS two-way FM digital system, dot for matrix backlit LCD screen, can be equipped with a variety of fixed-wing/glider and helicopters. Digital proportional radio control system is designed for all radio control models, giving you superior for protection against interference. Multi-channel frequency hopping, 2.408GHz to 2.475GHz system bandwidth range, each transmitter and receiver has its own unique identification ID that, once paired, it can reduce interference from other transmitters. Dual gain antenna, make signal transmission more stable, strongly, enhanced directional stability. Constructed with high sensitivity and low power consumption components, which reduces power consumption while maintaining high receiving sensitivity, and significantly improves battery life.
