Hi engineering team,

Is it possible to switch Starling 2 from Ghost Atto to ELRS?

Thank you

Yes, the wiring diagram found [here](https://docs.modalai.com/starling-datasheet/) shows how to wire an R/C. Both Ghost Atto and UART/CSRF-based ELRS receivers are supported

![pic2.jpg](https://forum.modalai.com/assets/uploads/files/1721700103640-pic2.jpg) Dear MODAL AI support team

Last month , You give me the advice  and I try to fix it.
However I hove not fix it.

I bought [Stariling2 with ghost Atto], but I can’t use it in Japan why regulated by rario raw.

So I try to change the receiver from Ghost Atto to ELRS one.

I think Starling2 support both the protocols.

I have used ELRS reciever for Starling1.

Do they have any difference from Starling1 to Starling2 at this protocol area?

Kind regards.![pic2.jpg](https://forum.modalai.com/assets/uploads/files/1721700123469-pic2.jpg)

@TOMPLA Are you saying that you swapped from Ghost Atto to ELRS and it isn't working? You have to change the RC configuration in the file `/etc/modalai/voxl-px4.conf` . Change it from `RC=GHST` to `RC=CRSF_RAW`.
