When the stick goes all the way down it will turn on a preset brake of low medium or high (dependent on manufacturer and model), not proportional like you want on a car. The reverse is a programable function, it's either on or off. You would need a programming card or a complex process of plug battery in, listen for tones, stick up/down through tone menu and then stick up/down to changes settings. Usually it's quicker to swap two wires on a brushless system, swapping 2 of the 3 motor leads reverses the direction.
The motor link no longer works, but it sounds like the motor rpm was a mechanical failure rpm, the point at which the magnets fly off the rotor. Usually you don't have to worry about hitting that unless you are running high voltage or a it's a very high kv motor. So most esc's should handle the actual rpm that you will be running at.
Hi.Here is the motor link again;
Can you please tell me which esc will be good for it from ebay.
