Since you misspelled Lynx, I'm wondering if you misspelled Spectra too. This is important because there are two completely different modules that work with the Lynx.

Spectra is Hitec's synthesized module that is 75MHz FM and will work with any negative shift reciever which has the appropriate crystal or synthesis. (Hitec or Futaba).

Spektrum makes the 2.4GHz DSM module and will work with any Spektrum receiver except the one for Futaba HRS.
