Anyone know how to start the RC service correctly in HITL simulation mode on the Starling 2 MAX with a Ghost Atto/Orca controller (using Voxl SDK 1.3)? (https://docs.modalai.com/orqa-ghost/) I noticed in the HITL there is mention of staring a CRSF rc input, but not the Atto RC input if different.

@LanSolo You can start the ghost driver by setting the following in `/etc/modalai/voxl-px4.conf`

```
RC=GHST
```

or you can start the driver manually with

```
qshell ghst_rc start -d 7
```
