Settings for Taranis X9D

This is to be expected!  You NEED to increase the frame rate any time you add channels.  The formula for doing this is:

Number of channels x 2.2ms + 4.7ms.

Thanks for that explanation.  Still wondering how to use the XJT-D16 protocol?  Do I select this protocol in the radio then attempt to bind with the bind button on the back of the radio.  Or is it better to just stick with PPM and increase the frame size? 
Thanks.
