Where did WPNAV_SPEED go?

I was wondering where “WPNAV_SPEED” went in the Mission Planner software ?

I see the variable in the “Config/Tuning” > “Arducopter PIDS” > “WPNav” section, but it is greyed out.

Has this variable been depreciated? If so, what replaces it? How do I control the ground speed to the next waypoint?

Does anyone know the answer to this??? I am absolutely stumped on this one too.


It’s not 3rd up from the bottom of ‘full parameter’ list?
