Alright,

R204GF-E not binding up to the 4PX, I have 2 new ones here and nothing.

The Receiver menu choice you pick S-FHSS and it is not like the T-FHSS where you link it with a timer and it stores and displays the link ID.

The receiver will only look like something is going on in S-FHSS mode when turning it on as it flashes green. Then after following the instructions after turning on transmitter and receiver you press and hold the link button on receiver, the green flashing goes away and off. Nothing happens, tried a few seconds hold to like 30 seconds.

Any ideas?
