I don't have 2.4GHz yet but am thinking of upgrading.

I understand that the Tx and Rx must be bound. I think it is also true that you only need to do this manually once - once the binding has been setup, it will be done automatically each time you subsequently turn the system on.

But what if you have multiple receivers. Say you have Rx A and Rx B in different aircraft.

You bind A and fly aircraft A for a few sessions.

You then decide to fly aircarft B. You manually bind it and then fly for a few sessions.

You now come back to aircaft A. Do you have to setup the binding againa or is it just a matter of switching on and flying.

It's just a matter of switching off the model you're done flying and switching to the new model you desire to additional "re-binding" is needed....

Just make sure you select the CORRECT model on your transmitter because with many systems, the transmitter won't do that automatically...

Been there, done that and old enough to know better.....

Just to clear something up, there's binding and linking.

Binding is the process of making the receiver memorize the GUID (Globally Uniquie ID) of the transmitter. Thats done once (maybe again when you're done setting up a model to set fail safes).

Linking is the process of powering up a system thats already been bound.

Spektrum and JR radios have whats called Model Match where in addition to memorizing the transmitter code it also memorizes the model memory number so that if you have the wrong model selected it wont link up.

Futaba and others do not, the reciever will respond to the transmitter its bound to regardless of the model memory selected.

You can bind any number of recievers to one transmitter, but you can only bind one transmitter to a reciever.

Airtronics SD10-G also has this feature, but only with the 10 channel receiver
