This is the Futaba R6208SB 3CH/18CH 2.4Ghz FASST S.Bus Micro Receiver. The R6208SB receiver accepts a wide range of batteries, from 4-cell NiCd and NiMH packs to 2S LiFe and LiPo packs, with no regulator required. PWM (Pulse Width Modulation) channels provide support for up to eight standard analog or digital servos. Using the S.Bus port, it handles up to 18 channels — and makes incorrect servo-channel hookups impossible. The R6208SB also features a high-speed mode that delivers ultra-fast frame rates on channels 1-6.
NOTE: High-speed mode is available only on Channels 1-6 and requires the use of digital (including brushless digital) servos. Channels 7 and 8 — which operate only in normal mode — can be equipped with either analog or digital servos.
