I am planning on mounting the VOXL-flight 90 degrees on its side. Where can I find the location of the onboard IMU and am I able to input an offset in QGC for the board to give the flight controller a better idea of where the IMU is? I know there is an orientation offset but what about a location offset in the X and Y direction?

IMU's can be found [here](https://docs.modalai.com/voxl-flight-datasheet-imus/).

Through QGC, the offsets can be adjusted: [here](https://docs.modalai.com/px4-calibrate-sensors/)

You'll have to configure the extrinsic files as well to match the rotation of the board
```
/etc/modalai/extrinsics.conf
```
Hope that helps!
