Advice on practicing backhand drop shot from rear court

I'm new to this forum but i hope you guys could help me out.

Any thoughts on right way to practice/execute backhand drop shot from rear court?
I tried practicing this but the birdy will fly like a backhand clear (high and but near the net) :crying:.

I like to learn backhand dropshots pro single players does (flat and near the net). Thanks for the help guys!!
