Pixracer R14 Telemetry on FrSky R9Slim Receiver

Hi, everyone.

I’m trying to get telemetry parameters discovered on my Taranis X9D+ connected to a FrSky R9Slim receiver on the Pixracer R14 running Arducopter 3.5.7. Everything works well when using X4RSB receiver, but not with R9Slim receiver. All devices are updated with last firmware. If someone have it working with R9Slim or have any tip to make it work, please, help me.

Thanks in advance and best regards.
