I just saw this: http://www.hobbyking.com/hobbyking/store/__62716__Turnigy_DSSS_2_4Ghz_Transmitter_Module_For_9XR_9XR_Pro_JR_Configuration_.html
and it seems to be the only module on the market that can utilise the internal antenna of the 9XR. I wanted to know if there are any users on the forum and whether it is any good? How would it compare to a FrSky module (I'm sure FrSky is better)? I also wanted to ask if the internal antenna of the 9XR is reliable. And how different is DSSS from ACCST?
As I see it, the main advantage of this module would be that receivers are cheap. FrSky receivers are pricey, and even though I have only a few models now, switching receivers can get annoying.
