Walkera 4F200 Tx/ESC settings for slow-startup?

Greetings all,

I'm looking for a way to have my Walkera 4F200 have a nice slow-spinning rotor throttle startup upon takeoff.

The Problem:
As it is right now, my 4F200 will not even give throttle response until I'm about 1/4 or 1/3 stick. Once I do get throttle response, my 4F200 will spin the blades quite suddenly and the tail kicks to the side, making my heli do a 180 before I'm even off the ground.

Things I've tried:
I've experimented with the normal throttle curve to make the "2 position" in the WK-2801Pro to be as low as 1%. It will still kick to the side pretty bad unless I make the "3 position" at 5%, which is at mid-stick (originally had it anywhere between 30% and 40%). This really won't do me much good when I try to go idle-up. Ideally, I'd like mid-stick normal throttle curve to be near 50% throttle when I decide to go idle-up, not 5%.

Perhaps this is something I need to program the ESC's settings for? If that's the case, I don't have an ESC programming card, nor have I ever changed an ESC's settings to begin with.

I'll say that this is just a minor problem I'm having with this heli that I'd like to have fixed if possible. It really does fly great when I have it up in the air, no problems.

I'm more accustomed to the way Spektrum has their computer radios setup, so the WK-2801Pro is something new to me, but I assume both radios have no differences other than where things are in the menus.

Everything on this heli is totally stock.

I appreciate any thoughts on this matter. I've heard more good things about this heli than bad.

If anyone can suggest the throttle curves they are using for this heli, that'd be greatly appreciated as well.
