RP3-H/CRSF ESC telemetry still unstable.

Running the latest Spirit GT firmware with the new wiring. The initial connection now works every time and I'm getting telemetry from both the receiver and Spirit GT/ESC. However the ESC telemetry occasionally drops out during flight (sensor loss warning), and then never recovers until I reboot everything. Receiver sensors continue working.

The question is what telemetry ratio am I supposed to be using with Spirit GT? When using Rotorflight with a CRSF receiver, part of the RF configuration is setting the telemetry ratio to match the ELRS setting in the transmitter. For Spirit there is no such setting, is it supposed to auto detect or am I expected to use a certain ratio? The latest revision to the wiki page has no information on this.

I'm experiencing the same. Initialisation is always stable now, but i keep getting sensor lost warnings now and then from spirit sensors. I would also like to know what the recommended packetrate is, next to telemetry ratio thats best for stable telemetry.
