The HoverAir X1 ProMax has some new features, thanks to a firmware update. Version 8.0.17 Side Track now has auto correction. Also, to use Co-Pilot in Side Track, you need to disable auto correction. Co-Pilot now works in all modes, however, in automated flight modes, co-pilot seems to be more of an interruption. You can view stats in real time and you can overlay them after the fact.
