Is there any way to increase the resistance of the sticks on the controller (not the software settings)? For elderly people who have decreased sensitivity, they are having problems with telling which way they are actually pressing the sticks, for example they cannot tell whether it is just forward or forward + left because the spring that forces the sticks to return to the central location is not stiff enough (they simply cannot tell if they are pressing the stick at all).I have seen things like this


but of course, a direct ability to set the spring tension would be much better. Is there a screw that could be used to modify the tension?
Thanks

Couple of videos showing how to set the spring tension in the older DJI controllers, but likely the same process in newer ones too.





You'll have to take off the rubber feet held on with double-sided tape to get the thing apart and take off the ribbon cables around the USB and HDMI port area in the later controllers.
