Hi

I can only let you know part of it.

xxxx KV means, each the motor will turn at xxxx RPM at 1 volt. So if it is 3000KV, means at 7.4V. It will spin at 3500 x 7.4V RPM = 25900 RPM. I guess then people covert it back to RPM what say 10T brushed motor RPM etc.

For the ESC, the A is the max current that the ESC can handle, it depended on not just the motor but the gearing the car will run (loading), if your whole system draws more then the ESC and handle, you will in the risk of killing the ESC.

but I don't know about the torque lah, sorry
