This is the Futaba R2006GS 2.4GHz S-FHSS 6 Channel Air/Heli Receiver. The R2006GS receiver auto-adapts to the transmission mode selected, whether it’s FHSS or high-speed S-FHSS mode. Plus, since it operates on a wide range of voltage, you don’t need a regulator even if you use a 2S, 7.4V LiPo pack as a power source.
