## Notes

{% hint style="warning" %}
Failsafe **MUST** be configured once with the desired channel values (hold or no pulses are not supported) while the RX is up (wait 10+ sec for the RX to learn the config) and then failsafe **MUST** be set to RX/Receiver otherwise the servos will jitter.
{% endhint %}

Telemetry: the 2 RXs I have are sending different information in different format

* RX-5: RX\_RSSI=RSSI=sort of RSSI or link quality, RX\_LQI=number of connection lost, TX\_RSSI=RSSI from the TX perspective, TX\_LQI=percentage of received telemetry packets
* RX-9-DR: A1=RX Batt (Ratio=12.7), **RX\_RSSI=TX\_LQI**=percentage of received telemetry packets **from the TX** perspective **not RX**, TX\_RSSI=RSSI from the TX perspective, TX\_LQI=percentage of received telemetry packets
