Today, I build a mount for the dual Garmin GSU 25 ADAHRS (Air Data and Attitude Heading and Reference System). These redundant boxes take in all the air data like pitot ram air and pressure from the static and AOA ports and feed it into the G3X system. They also have electronic gyros in them to provide attitude information.
The subpanel that these are mounted on is slanted forward a bit, so I built a mounting plate to keep the sensors perfectly vertical. I believe the sensors have settings to compensate for a tilt like this, but I figured it wouldn’t hurt things to get it as close to vertical before having to tweak things.
