You can slow the YAW rate even more with this:
BEFORE you begin installing, if you have the current version of DJI Assistant 2, rename the directory it is installed in.
C:\Program Files (x86)\DJI Product\DJI Assistant 2
A or whatever you prefer.
1.1.2 installs into the same directory and will hose everything unless you rename something in the path.
1.1.2 is not capable of performing future firmware upgrades (or any from what I saw)
After you change that, make sure you update the shortcuts.
Once you get that, follow the instructions in the video to connect and turn on your controller.
Go to basic settings on the left.
Remote Controller on the top.
Control EXP on the bottom.
In here on the right, you can control the max pitch angle, max ascent, max descent and the YAW rate.
On the left, you can change the sensitivity of the sticks (not the rate).
I used this to change the YAW/ Roll sensitivity because in Sport, seems like I would sneeze on the sticks and the craft & Camera would tilt max.
Again, the controller stores these settings so it must be on for the programming.
Also, there is a screen for P & A (position & Atti modes) and then a screen for Sport.
Switch to sport mode on the controller to change the sport settings.
Settings are auto saved.
