At least they are using the acronym in the accepted way (FHSS has always meant "frequency hopping spread spectrum")
Futaba S-FHSS uses the TI CC2500 chipset (as per Hitec/FrSky/Graupner (I believe)/Corona/et al). It's configured to use 2-FSK modulation and it hops over 31 channels.

So no DSSS.


As a side note, does anyone know of any peer reviewed papers on long range links using 2.4GHz with different modulation techniques?
