Hi, all. I'd both Frysky R9 slim plus OTA with the following build with FPORT connection (Inverted)

(Master)

smartport - TX1 (FC)
VCC - 5 volt (FC)
GND - GND (FC)
SBUS IN - SBUS OUT(SLAVE)

(SLAVE)
SBUS OUT - SBUS IN(Master)
VCC - 5 volt (FC)
GND - GND (FC)

Is this correct?
Master receiver is working fined, but it won't worked (motor won't spin) when I unplug master and leave the slave to take over the control.
I'm using Jumper T18 with previously defined bind under same receiver '00' for both.
Telemetry Ch 1 to 8 (ON) = Master
Telemetry Ch 1 to 8 (OFF) = SLAVE

How to fix it, TQ.
 
Questions about those r9s are asked here occasionally but I don't think members here use that protocol so they never get answered lol.
If you figure it out let us know.
