Thank you guys, The TRIPLTEK Mini is not an upgrade for any of the TRIPLTEK tablets. For the TRIPLTEK 7 and 8 users who enjoy flying with a large display, the TRIPLTEK 9 is the natural upgrade because it is a professional tool with the most powerful system and the best display of all other Tripltek devices.
The TRIPLTEK Mini is for drone users who want a small portable true sunlight-readable display instead of the DJI RC(no sunlight readable) or the RC PRO, so they can edit, upload videos to social media immediately, transmit live video, use third-party apps to check the weather, maps, places to fly...
With the advantage of a bright display, portability, and a device that will work with all your drones as opposed to the DJI RC or DJI RC PRO.
Also, the DJI RC2 costs about $370, so for $200 more you can have the TMini with the features of the DJI RC PRO which costs $1200, and use it for many other tasks, like as a monitor for a DSLR camera, GPS navigation for bike, or any outdoor activities.
