Howzit, welcome back to a fantastic passtime.

Youhave a Futaba T7C which is a Futaba Advanced Spread Spectrum Technology Transmitter. It transmits a coded signal across around 30 odd channels within the 2.4GHz bandwidth.
In the hobby they call this a hopper or frequency hopping transmitter.

If the Tx is frequency hopping, the Rx needs to know where to go looking for it so it too needs to be a FASST Reciever but needs to know to look only for the coded IDof the source Tx.

Myunderstanding of howFASST works is that it sends out a burst of information containing,
1) the Tx ID so the Rx knows to respond only to it.
2) the command so the Rx can distribute to the correct channel (this much hasn't changed)
3)where to go looking next

each control input initiates the above cycle. It creates a robust solid link between pilot and aircraft.
In order to enjoy this monogamy, a receover has to be bound (married) to the Tx. To do this with a Futaba Tx and Rx is simple.
First make sure there are no other Futaba FASSTTx operating close to your Rx.
Switch on the Tx.
usng the little plastic screwdriver provided, press down the tiny button on the Rx thats labelled "LINK".
Now poewr up the Rx and hold the "LINK"button down for 2seconds and release. The LED will blink red for a few seconds then switch to green. Your Tx and Rx are now married.

If only marriage were this simple...
