I'm beta tester of Litchi for Mavic Mini. I realized Focus mode is a great improvement over standar DJI Fly app.
I tested Mavic Mini Litchi aplication Focus feature at this amazing six hundred years old castle at Spain. Prior that entering Focus mode you have to place a POI marker at map view. As soon as you start Focus, Litchi takes control of Mavic Mini yaw and Gimbal camera tilt. That way, you can slide, get closer/away, go up and down and Litchi will take care your subject is always well framed. You only have to relax and fly looking for the best point of view. Overall traking is very smooth. Take into account I'm flying almost one kilometer away. Focus setup screen allows you to decrease stick sensitivity for achieve better results.
I used a Mavic Mini CE model. 5.8Ghz band at channel 159. Litchi beta for Android version 4.18.8 Beta-G build 3630
Hello there R. Thank you for reaching out and for sharing this video that you have created and for this information about the Litchi application. Nice flying and just a reminder to please use the recommended DJI application ( DJI Fly application ) when flying your DJI Mavic Mini to ensure stability and comparability during flight and 3rd party applications like Litchi can void the warranty of your DJI Mavic Mini. Thank you and safe flying always.
