Two models and one radio.

Hello,
I have two same helicopters with 3GX mrs modules and a radio. Currently I made a template copy. But the problem is that they run together. I would like to know how to make sure they do not work together.
Thank you.

I did it, but after the rX did not bind anymore. BTW I use a DSMX satellite to run with the Futaba RX . Could you tell me more about fixed ID, and can I use with the DSMX protocol?

I thank you vlad_vy. I re-tried and everything works fine with a fixed ID for each model. I think I had not waited long enough for the bind to happen.
I do not understand exactly how all this works because on page 47 of the manual it is written "If Fixed ID is set None, a transmitter-specific ID is used instead".
I thought that if I did not put a fixed ID automatically, there Would have one generated.
Thank- you for helping-me.

The generated ID for DSM is transmitter-dependent, but not model-dependent. So you really need to set it yourself. I'm not sure why we don't make it model-dependent to prevent that, but we don't.

Different protocols do different thing with IDs, from ignoring them to requiring them, so this answer may not apply to other protocols.

Thank you very much for your reply and for your work.
