Electric R/C is different from Nitro and uses its own unique language. I came across this article which will be usefull to those interested in electrics
Please note that it is broken up into 3 posts: ESC, Battery & Motor.

Speed Control Lingo:
Firmware: The program on a speed control, radio or receiver that can be updated.
Why it matters: Manufacturers of ESC's often release software updates to make the products more reliable or add features and functions. This is usually performed by downloading firmware updates from a website & uploading to the device via USB cable.
Linear & Curves: "Linear" means the t/b work in the exact same proportion as the transmitter's trigger is pulled or pushed. Pull 50% trigger, get 50% throttle. A "curve" is used to increase/decrease that relationship. A typical throttle curve will decrease the throttle response at the low end.
Why it matters: Curves are 1 of the best ways to tune your truck for driveability. Adding a gradual throttle curve can be used to tame high-power brushless systems for off-road use.
LiPo Cutoff: A speed control setting that automatically cuts power to the motor if the battery voltage drops below a certain voltage; this is to prevent LiPo batteries from becoming damaged.
Why it matters: Lithium-based batteries can be permanently damaged if the cells are allowed to be discharged to about 2.6v per cell. If your speed control doesn't have this feature and you want to use LiPo's, then get an external cutoff or at least an audible alarm that lets you know when its time to end the run.
Punch/Traction Control: Speed control setting that basically limits the amount of current that's passed on to the motor during acceleration.
Why it matters: Adjusting punch to the highest setting that you can use without breaking traction will gain you more run time and more control. Remember that too much punch control can also limit top speed.
Start Power: The amount of current sent to a motor to get it to move from a standstill.
Why it matters: If the motor hesitates, then decrease the setting. If it still hesitates at the lowest setting, batteries with a higher "C" rating might be needed.
Trigger Dead Band: the amount of trigger travel needed before the motor responds.
Why it matters: Sensored brushless motors are incredibly responsive, so sometimes a larger dead band is needed to prevent unwanted car movement.
Drag Brake: Speed Control (ESC) setting that applies an adjustable amount of braking when the trigger is in the nuetral position.
Why it matters: Use Drag Brake to make it quicker to lock up the tires and rotate the rear end for tight turns. It also makes your brushless motors feel more like brushed motors when off-power.
