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%.

Speculations:
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.

Or perhaps this is just how Walkera helis are? I've had several helis in which I can have a nice slow startup 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.

Comments:
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.

I really typed out a mouth-full of a first post for a minor problem like this one (I tend to do that, and I apologize). My main problem is in the first sentence. Anything after that is just my experience and information for the problem.
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. I'm aware there's a dedicated thread to this heli, but seeing that the latest post is more than a year old, I thought it'd be better if I made a new thread than to try and resurrect and old dead one.

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