Parameters related to brake

Final deceleration of the last way point is rapidly brake is applied.

Is there a parameter to relieve this?

WPNAV_LOIT_MINA : min acceleration in cm/s/s. Higher values stop the copter more quickly when the stick is centered, but cause a larger jerk when the copter stops…

This should be the parameter you are looking for.
