The R7108SB may also be switched to the FASST (Multi-ch/7-ch) system that operates without telemetry.
It features bi-directional communication with a FASSTest transmitter using the S.Bus2 port. Using the S.Bus port, an impressive array of telemetry sensors may be used. It also includes both standard PWM output ports (channels 1-8) and S.Bus output ports.
