The FGr4S receiver is the ideal support when using a Flysky remote control. The receiver makes use of a technology used by several Flysky transmitters - the automatic frequency hopping digital system (short: AFHDS3). With a bidirectional transmission system via the antenna, this receiver is specially designed for the installation and output of PWM/PPM/i-BUS and S.BUS signals. All AFHDS3-capable transmitters are supported.
