Hi, I have a futaba 4PK-2.4G FASST radio with a R603FS receiver which I have no problem binding. The store sold me a Futaba receiver R204GF-E (S-FHSS) that they said would work with my radio but I can`t bind it. When I opened the package it says futaba S-FHSS/FHSS system does not work with current Futaba FASST system. If someone out there knows how to make it work I would greatly appreciate it. Thanks pete

Yep, the R204 does not support FASST so no way to make it work.

The only way to make it work is go back to the shop and get the right receiver.

Thanks for the quick response, I will take it back to the store.Love this site you guys are so helpful. Take care pete::
