This latest Firmware really wasnt ready for prime time and looks like they changed a bunch of setting values. Pan is jerky just like other comments.

How do I go back to the previous firmware, I cant find instructions.

The lates firmware is unusable

Went back to previous firmware and everything working like normal.  Correct, the latest firmware is unuseable unless you like jerky motion.

It seems that the people of DJI are not aware of the problem

Its hard to believe they tested this before putting it out.

this is very interesting

I really hope that they just didn't test it. On the other hand, I'm afraid that they will leave it like this and then release new RS3/RSC3 that will "fix" the problems...
