My latest email with FS reveals it is hardware limited. My version is 1.0. I'm not sure what version they are on now.

They are going to mail a new main board out to me so I can swap it out. They say this will allow the multi model memory to bind to different receivers.

So I guess if this is holding you back it should be fixed on the latest versions of the radio. I'll let you know how mine is working when I get the new board in.
