In recent updates I have been introducing to FPV Air 2 it's own track editor!
The track editor has a unique interface design aimed at allowing pilots to quickly and easily create unique tracks for practicing new lines.

Making new lines to practice on keeps your skills flexible and dynamic which is much better suited for real life racing events where the track often needs to be learned fresh at each race.
You can watch the short tutorial video I've made explaining how to use the features of the editor here;
