Compatibility:
The CORONA 2.4GHz Spread Spectrum FASST Compatible Receiver is designed for use with FUTABA’s FASST 2.4GHz transmitters; including the 3PM,3PKS,3VCS,3GR,4PK(S),TM7, TM8, TM10, TM14 and the T6EX-2.4G, 7C-2.4G, 8FG, 10CG, 12FG. The R4FA-SB and R6FA-SB receivers supply a more useful mode for users. Both the R4FA-SB and R6FA-SB support FUTABA’s FASST air system and surface system. The R4FA-SB supports 7-channel with continuous PPM (positive and negative) output ,RSSI output and S.BUS output, R6FA-SB supports 6 channel high speed PPM(HS) mode to optimize helicopter response control and S.BUS output.
Under S.BUS output mode, both R4FA-SB and R6FA-SB supply 12 proportional channels and 2 DG channels. Therefore, the R4FA-SB or R6FA-SB becomes 14-channel receivers when using S.BUS output.
