RadioMaster Tx16 with JR module issue

[XPS]

XJT mode is required if you need more than 8 channels. It's also a faster protocol in general, so it should be used when possible.

The issue with XJT mode though is that you can turn on/off the channels that are used. Once you have bound the receiver you can't turn on/off channels at that point (unless you rebind again after doing so).
