We pre-install many maps and elevation files to make AIR³ ready to fly.
It's easy to free up memory. Just go to /XCTrack/Map/RoadMap for AIR³ 7.1 and 7.2 or /Android/data/org.xcontest.xctrack/files/Map/RoadMap for AIR³ 7.3 and delete the maps you do not need. You will quickly get a lot of free space ! Watch the video on maps and elevation files to quickly get acquainted with these topics.

Alternatively, you can also get a 128 Gb SD-card with pre-installed maps of the world .
