Hi @MorgannLBT –

For ArduSub to accept RC overrides you will need to make sure that mavros is the GCS. The typical way to do this is to set the system\_id to 255.

Here’s a long-ish thread discussing this: [RC override not working with SITL ArduSub + Mavros - #8 by patrickelectric](https://discuss.bluerobotics.com/t/rc-override-not-working-with-sitl-ardusub-mavros/12046/8)
