New to RF. Have NX10 TX which I cannot get to 1) Calibrate (throttle stick won't register at all) and 2) I cannot get all 8 available controls mapped to a config file. I updated TX firmware to 3.13B. I've looked through forums and downloaded Flightengr's tutorials on controller setup but I cannot edit any of the "base" controller config files (e.g. SpektrumNX Series (WIRED USB), Spektrum Receiver (7+ch) to fully map NX10 switches to the config file. I'm using the wired USB connector (No dongle). Perhaps not understanding the relationship between TX models, TX control assignments within a model and then RF controller assignments. Any enlightenment on the overall process or the nuances of controller editing and configuration would be appreciated.
