HANGER 360, brilliant .<snip>...
Hangers related (main) app Autopilot<snip>..
i was keen to charge on with Litchi but some of their flight modes are suspended pending bug fixes by dji (as reported in litchi site)
The DJI firmware bug that effected some of the Litchi flight modes also effected Autopilot and Hangar 360 in the same way. So using those apps would not have avoided that issue.
However DJI fixed the bug with the release of firmware .600 so none of the three aforementioned apps are effected by it anymore. If you are still on an old firmware that contains the bug, there is no point using the other apps as a fix, because they were equally effected.
