How do the modules work? Is there a module for all of the major brand radios? So if i get a FM JR radio and get a spektrum module and the spektrum stuff eventually fails i can switch to futaba module? I have heard people talking about the modules but have never looked at them so i don't know about them.
Goran, the future is promising for module based Tx! here's pic of a Hitec module for JR Tx to come out with matter of weeks>see the thread bellow POST#9

I have Spektrum now and had no problems so far. But if i lose more than one plane due to "unexplained" circumstances (or even an explained one that i don't like

) i can just replace the module with the Hitec one and be done with it.
Hope this helps,
V.
