Here is what I did with my sphere. I sold my Air2S and I decided to design a frame for the mini 3pro. I see people mount the sphere as it is on the mini 3 Pro but I wanted to reduce the distance between the lenses and also to be lighter. Altogether is 124g including the battery. The original frame of the sphere is 219g so I save like 95g which for the mini 3 is a big difference. Leave a comment if you like.
I did some test flights and I may need to change the position of the top camera because I didn't get enough satellites. When I am done with testing and I have good results I will make a kit and a tutorial available.
