Due to a special method, the FUTABA FASST transmission combines the advantages of the DSSS (Direct Sequence Spread Spectrum) transmission technology with the FHSS (Frequenz Hopping Spread Spectrum) transmission. The unique FUTABA FASST system with its perfect combination of the advantages of DSSS and FHSS and the extremely high reliability and interference immunity has already convinced many pilots.

The FASST transmission has been expanded by telemetry and is called FASSTest. The advantages of the FASSTest hybrid system take full effect in the bidirectional transmission (control function and telemetry data).
