Futaba introduced FHSS (Frequency Hopping Spread Spectrum) systems in 2010, to offer modelers a less expensive way to enjoy 2.4GHz dependability.
Other advantages include extremely low latency, exceptionally fast frame rates, transmitters with no external antennas and low-cost receivers with Easy Link convenience.
As the name implies, the transmitter signal of an FHSS system literally hops from frequency to frequency in a pseudorandom sequence. The combination of frequency hopping with Futaba's advanced algorithms creates 100% frequency security.
Futaba FHSS and S-FHSS systems are also compatible with models that display the FTR (Futaba Transmitter-Ready) symbol. It means that the model's factory-installed receiver is FHSS-compatible and can be linked and used with an FHSS transmitter you already own.
