I am still not convinced that Futaba is doing true FHSS. All evidence points to hopping DSSS. Different deal.
Futaba's own application for FCC approval claims that FASST is DSSS.
afaik from very limited knowledge, all the alleged FHSS model systems are not FHSS, but DSSS that changes channels rapidly, which is technically different from FHSS. What they heck, they work superbly well, however it is they are achieving it.
