I'm starting to use Litchi more, and absolutely love it. I had some questions that their help/web site doesn't seem to answer, and wanted to know if anyone knew a good resource: 1. When designing your mission, are the altitude inputs relative to where the drone takes off, or is it sea level/something else? 2. I've read the very clear warning that P3S will not return to home if contact is lost in most of the Litchi modes (which is insane). To be clear, the drone will RTH if the signal is lost in a waypoint mode mission (unless you specify otherwise in the settings), correct? Having any drone sit and hover when contact is lost is absolute suicide, and that part of the Litchi/P3S combo is what makes me hesitate to send it out too far. 3. Any recommendations on using interpolation vs other methods, such as POI? I believe you have to manually input the gimbal angle using interpolation, so not sure how anyone would know that if they're designing the mission on their computer 4. Finally, is there a setting I'm missing for dynamic RTH? I don't want the drone to land where it took off from - I want it to land where it detects the RC is currently.
