Hi,

I ran the ```voxl-configure-mpa``` command on our Starling 2 drone (SDK 1.5.0). Unfortunately, I didn’t realize that this command also resets some of the PX4 parameter configuration files, and since then the drone seems noticeably more unstable in flight.

When we got the drone, I pulled the /data and /etc/modalai folders to my local machine since I thought these will contain the important configuration.
From the command output, I can see that it also overwrote the following files (among others) in the /usr/share/modalai/px4params/v.14/ folder:
- platforms/VOXL_2_defaults.params
- platforms/D0014_Starling_2.params
- other_helpers/starling_2_indoor_position.params

My questions are:
1. Is there a way to restore or recover the previous parameter files that were on the drone before running voxl-configure-mpa?
2. I found the [GitLab repository](https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-px4-params) with parameter files, but it seems to only contain the new defaults (the ones that replaced my old configs). Where did the original parameters that shipped with the drone come from?

Thanks a lot for your help!

@saegsali If you have the param file saved you can either load it through QGroundControl or with `voxl-configure-px4-params --file $NAME.params`

Hi @tom,

Unfortunately, I don’t have a QGC file with the parameters. Do you know where the original parameters come from when the Starling 2 drone is shipped? Are they the ones from the voxl-px4-params repository?

Thank you in advance!

@saegsali These are all of the param files loaded on Starling 2 (D0014) by default:

They can be found here, organized by folder:
