X10+v2 and ELRS

[XPS]

If you have the X10+ setup to control the failsafe positions then that is what will happen during a failsafe. The only issue you might run into is what the receiver itself does. I have seen various receivers continue to send a the SBUS packet with its own failsafe positions when the signal from the transmitter is lost. There is nothing the X10+ can do about that because the input signal is what it monitors.
