Alright im a starter with electric cars but not a new beginner with fast r/c I used to play with on road nitro before so Please I dont want any comments saying It will be too fast start with something slower...

I would like to know which can do the job? I want Performance and Race capability mamba max set up... for my kyosho ultima RT5

Ive noticed 4600Kv 6700Kv 7700Kv... from castle creation

How do I make my choice?

once thats settled... How do I pick the right batteries for the right ESC?

eg: 2s Lipo with 5500 mah... 40c? what the hell are those numbers?
40 current? 2cells Lipo 5500? discharge rate?

May I have a chart and explanation of all this?

the more mah I have the longer It will run?

I have a 1500$ budget but I wouldnt want to buy a 200$ Lipo that will not fit my setup...

thanks for the help
