stupid question time..

Lets say I have 2 esc's.. one has a 120amp out put and one has 150amp out put.. does that translate to more power delivered to the motor or ? Trying to navigate all these esc's to figure out whats what.

thanks for any info..

Well... it can provide more power - to motors that need it. It will not shove more power down any motors' throat. Another way to put it: on lower powered motors there will be no difference. 120A was (or still is) the norm even for TC mod, etc. and should be more than enough for most applications. Oh and just the number of amps is not all that makes up a good ESC, keep that in mind, too.

makes sense. just trying to make heads or tails of the specs on these things lol

What makes up a good esc other than amps?

Mostly their firmware. Which parameters you can change (even in blinky class, without boost/turbo, there can be some interesting left), how smooth they deliver the power, strong or weak brakes, etc...

At least for racing, these mostly count more than just the number of amps (once you got enough to run the motor, that is). For speed runs, bashing, or heavy cars (e.g. 4WD SCT), these things might have less priority than amps.

Thanks, I'm trying to get into racing and its been kinda hard to pin down the difference between a $40 ESC and a $200 ESC

That is just the rating of the ESC, it must be equal or greater than what the motor/battery combination will require. The power you get will depend on the motor and battery combination you use.

Remember however, that higher price does not always equal being better (or having more options). It's important to look at each ESC (company and model) individually, its pros and cons, and the experiences people have made with them.

Depending on what type of car and/or class exactly you're going to race, you can get away with less (in some cases much less) than $200 - without giving up anything important, be it performance or setup options, etc.

On the other end of the spectrum, I daresay you'll probably not find a $40 ESC that can keep up with a $200 unit in all aspects. Up to some point, you simply get what you pay for, but then again, some products are just more expensive than others, without any apparent reason. Finding the right combination of quality, features, performance and price for one's needs can be quite a balancing task for all of us in this hobby.

I would get one that can run blinky and mod so you have more options if you decide to run a different class. SMC 120 esc is a good one for the price. About 90
