The FlySky INr4-GYB is a compact 4-channel AFHDS 3 surface receiver designed for RC cars and boats. It features a built-in high-performance gyroscope, single-antenna bidirectional transmission, and support for battery voltage detection.

With 4 NewPort function interfaces and multiple output options including PWM, PPM, i-BUS2, S.BUS, and i-BUS, this receiver offers flexible setup options for a wide range of surface models. Its small size and light weight make it easy to install, while the splash-proof design helps protect it during everyday RC use.

The INr4-GYB is compatible with FlySky surface transmitters that support the AFHDS 3 protocol. Please note that the gyroscope function is currently only supported when used with compatible FlySky Noble series transmitters.
