### RSSI_SCALE setup method
To calculate the rssi offset and scale, check the rc value at full signal (`rssi_fullsig`) and at almost no signal strength (`rssi_nosig`).
Then, calculate the offset and scale values using the following formula:
```
rssi_offset = 1000-(rssi_nosig) / 10
rssi_scale = 100 * 1000 * (rssi_fullsig - rssi_nosig)
```
Examples are:
| RC System | RC value at full strength | RC value at no strength | `rssi_offset` | `rssi_scale` |
|:----------|:--------------------------|:------------------------|:--------------|:-------------|
| Graupner | `1900` | `1100` | `-10` | `125` |
Then set these values via CLI:
```
set rssi_offset = -10
set rssi_scale = 125
```
