Descent and landing

Hi, I’ve had this heli for a few days. My first and must say its a beauty and very fiesty too. Not using auto governor and mostly on realistic settings, taking off and landing is 50% successful up from 0% just a few days ago. Once in the air, its quite tame and flies nicely almost like on auto pilot once properly trimmed.

So I am just curious to find out what settings should be used for descent and landing. For me, it starts off in a very slow controlled descent which out of nowhere transforms into a scary roller coaster ride closer to the ground. I was under the impression that ground effect is supposed to cushion an aircraft but i find controlling it under ground effect much more difficult than when higher up. Please dont judge, am very new to helis.
Thank you
