# Payload Swapping on Herelink (IGC 1.3 and Earlier)

{% hint style="warning" %}
**Note:** This process only applies to the Herelink GCS running IGC 1.3 and earlier. IGC 1.4 removes the need to conduct the following steps. See [Installing IGC section](https://docs.inspiredflight.com/inspired-documentation/products/inspired-suite/inspired-ground-control-igc/how-to-update-install-igc) for more details.
{% endhint %}

**This process is mostly automatic, but has two manual exceptions detailed below:**

1. First, manually adjust the [**Herelink Settings**](#how-to-update-herelink-settings) to suit the payload. Buttons profiles are saved to the device, simply select the corresponding profile, and your IGC controls will update to match the payload. Then change the W axis channel for Joystick settings. 
2. When switching from LR1 to Vio or vise versa, IGC will alert the user with an on screen prompt that a new payload has been detected. [**Tap the "Apply Payload Params" button**](#how-to-apply-payload-parameters-on-igc) to allow the swap feature to progress.
