Possible to adjust throttle descend?

My quad may be a bit on the heavy side. over 6lbs.

Is there a parameter to adjustment I can use to make descending more smoother or linear ?

It seems once I am at mid throttle hovering, if I pull the throttle down a bit. It starts to descend a bit too fast.

This might help you:
