Features: The FS-A8S is a compact one-way receiver. It is designed for multi-rotor aircraft. It uses the AFHDS 2A (Automatic Frequency Hopping Digital System) protocol, and supports standard PPM output as well as has i-BUS support for up to 18 channels. The receiver is suitable for FS-i4, FS-i6, FS-i6S, FS-i6X, FS-i10, FS-GT2E, FS-GT2G, FS-GT2F RC transmitter. Changing mode (i-BUS / S.BUS) is simplier and easier.
