I'm looking into getting a 6XHS on the HAM band for some experiments. I was wondering if anyone knew if there were extra dormant channels on the 6X that could be tapped into? Has anyone ever seen the frame output from a 6X on a scope? If it absolutly doesn't, does anyone know of any cheap 6 channel computer radios out there that do? I just need a simple transmitter for a heli, with as many extra channels (switched or proportional I don't care) that aren't used by the radio as possible for custom controls that I don't want the radio itself to "know" about, just transmit.
