Run esc and brushless motor from power supply?

[BrianG]

Depends on how the supply handles overcurrent situations and whether it is a linear or switching supply. Some may simply shut down. Some may blow an internal fuse. Some may exhibit drooping output voltage. In all cases, the ESC (motor actually) will try to pull what it needs to do what is being asked. To have the ESC "stop" once it reaches X current requires the ESC have some kind of built-in current-limiting and then program it.

Whatever you do use, I would add a large (~6-8A) Schottky diode across the regulator circuit. When you apply brakes to a motor, it will generate a reverse-voltage, and if this voltage is higher than what the supply is outputting, the regulator circuits could fry depending on how they're designed. Adding the diode to a switch mode supply may be a bit tricky and is more complex than can be described here. However, if using a linear supply, you would add a reverse-biased diode across the regulator circuit (anode to the PS output, cathode to the rectifier). That way, if the voltage from the ESC does get too high, that extra power will be shunted directly to the rectifier.

Thanks BrianG for your input, I still don't have the Power supply, but plan on purchasing a switching supply, as i will be shipping it abroad, doing some research got to know that the linear power supplies are bulky and weight a lot, so i will get a switching supply. something like this
Universal DC 12V 30A Regulated Switching Power Supply

I like your idea, a fuse could be my best bet. maybe i can torque control the Mamba Monster to limit the current also.

The diode idea seems great, but excuse me did not understand the second paragraph... no worries appreciate it a lot, will give me a lead on some research....

If all goes well might add another power supply in parallel as bruce750i suggested for heavier milling cuts. (an identical one would be a safe bet.)
