I am familiar with A & B
All I have read about C is that DJI has reduced the tx output (effectively reducing the range). This is just what people have said in response to FCC papers so I do not know it is true.
I would really like to know more about your stated differences. As for the firmware / camera speeds, I'm finding this difficult to believe if not understand.
You may be talking about firmware 1.6 which has blocked everyone from downgrading past 1.5. And as far as the camera speed, this has been adjustable from within the DJI go app for a while.
So with all that said, I really am excited to hear more about what you said !!!
