Ok, that helps me.
Armed with this new idea (for me) I set up a model in the Taranis using PPM with 4 channels and a 14ms frame rate (4ch x 2.2ms + 4.7ms). I configured the RFU and the X10+v2 to communicate using SBUS. It worked! The RFU bound to the XPS transmitter module and the X10+v2 had a solid green light, and servos plugged into channels 1 through 4 on the X10+v2 operated smoothly.
Then I tried the same PPM 4-channel and 14ms configuration in the Taranis with a DragonLink transmitter module. The SBUS output from the DragonLink receiver to the X10+v2 seemed to work a little better this time as the X10's green led was showing random less frequent single blinks about twice per second - not a steady 10x per second blinking like when I fed the DragonLink transmitter module directly from the Taranis with SBUS. The servos worked relatively smoothly, but there was still some notchiness and I think that some control data was being lost.
So thanks to your advice I got the RFU to pass good SBUS on to the X10+v2 (and presumably other devices) provided the XPS transmitter module is fed with an appropriate frame rate.
With DragonLink I tried multiple settings including SBUS and PPM and varying the number of channels but I could not get it to deliver a good SBUS signal to the X10+v2. DragonLink is no longer supported so I'll probably never know how to work with their SBUS implementation.
