Tuning Electric?????

[mustbnitro]

I just finished my Feiago and mamba powered 8ight-t and took it out today. I am convinced, this thing is fast, yes I can pull a wheelie with a truggy. I am wantint a few pointers at tuning though.
Set-up:
Stock Mamba Max settings w/ 12V cutoff set
Spectrum DX3.0
Feigao 9XL

Problem:
I have not set-up an electric in over a decade! I have to pull down about a 1/4" on the trigger and it just takes off, trigger pull before movement, also no easing into power. I don't want to lose power, just be able to ease into it and yet have full throttle if I want it. Not to mention the brakes lock it up.
-What do the radio settings effect?
-Mamba settings?
throttle curve(i know what it is, but any hint on a race curve set-up)?
punch?
timing?
anyother settings that help?
I am lost and need help tuning so i can actually be able off-road rae and not drag race which is waht it is like. I'm lost. Thanks!
