Just wanted to add to this. Deadzones in general on analogs are not adjustable. Not on foot or in vehicles and it makes things exceedingly difficult.
It's already a huge disadvantage to go against M & KB users with an analog controller. No deadzone makes it significantly harder.
Flying a helicopter with a dual analog, the left and right ananlog having no deadzone make the first 50% of the controller do nothing. Really hurts the mobility imo. Thank you for adressing this issue.

There are already half a dozen topics, stating this problem..

No. This happens. I can be just going along and out of nowhere my whole rover arm just falls off.(Has happened twice) Also it happens with my Radiation detection unit very often.

Likewise, confirmed.
