ESC comparison question
 

I am just wondering what the advantage is if any to running the MMM when it comes out versus the MM. If you are running the exact same motor and battery what will the advantage of the MMM be over the MM? I am just curious. Thanks

One comparison is the voltage limitations. The MMM will be able to handle the voltage. Most run the MM, but it's not really supposed to be used in the maxx's and revo's and such, 1/8th scales. It's designed for more of the lighter vehicles. The MMM is to be made for the heavier vehicles.

I understand that. But will the MMM make the vehicle any quicker with the same motor and battery setup? I am thinking it will run cooler correct?

From what I can gather (since no one has a MMM yet) it uses lower resistance higher voltage Fet's (the switches) so it should run cooler and therfore more efficiently... Either way it's built for 6S instead of 3S so if you have a problem with it while on 6S it will be "within specs" and therefore under warranty. I just want to know if it will run on 8S ;)

(and it comes with a "neu" style motor)

okay thanks for the info guys.

I agree, it should run cooler. But the esc really is not what makes a vehicle faster per say. It's voltage and motor.

It could make your vehicle faster if you have a bigger motor or taller gearing, as it has more power overhead. 70mph in a stock emaxx anybody?

I am just hoping for a good 50 mph with a Neu motor 4s or 5s and the MMM.

Neweuser, resistance is voltage drop. I wouldn't claim you would see a difference in speed (with a given motor/gears/battery/vehicle) between the two controllers, but at some point there is a difference...

I want 75mph out of my Ofna Hyper7, 6S, MMM and supplied motor... without the "flash bang grenade" effect at the end of a run :)

I never claimed you would see a difference in speed. But the esc alone will not make your truck "faster", there are variables included as you mentioned above. "motor, gearing, battery, vehicle". With the larger esc however, you could add more voltage, bigger motor, and of course a taller gearing. This also depends on the vehicle, but again, the esc alone will not give you more speed. If you use the same motor, batts and gearing in the same vehicle, how would a larger esc make you go faster?

Yes that was the question guys. Identical setup except a bigger, better ESC on one versus the other.

Lower resistance= less voltage drop, less voltage drop means more of the battery power getting to the motor, more power at the motor=faster. Yes, a better esc will make your ride faster. (That is why every advertised esc lists the internal resistance)

The resistance IMO is so minimal, that you are not going to go from 60-70mph by any means.

I agree, no 60 to 70 leaps. But let's not forget to include the better wires on the MMM what would they account for? (splitting hairs to guess at mph increases) but true to the question, blah blah, better esc is better, blah, blah.

So long as I bow out before anyone is upset... Have a good turkey day all, don't foget to get out and play with your stuff, I will.

Hehe, not saying I disagree with the resistance factor. In this case however, I would think that the minimal difference would only matter to a serious racer. In any case, a bigger, better esc is always good to have. More efficiency in general is always a good thing. Larger, shorter wires, good connectors...bibility blah blah....diggity doo dah....

If weather here prevails to be good, I would hope I can get out to run my truck one last time! Already hitting 30's F*.

Good Turkey Day to you as well :yipi:

Ya'll are right. Things like lower IR and bigger wires certainly heat, and sometimes it can be pretty significant. I've noticed gains from simply going to Deans connectors. Another aspect to look at is that the MMM will have more amp handling capabilities, so given everything is the same. Motor and battery, and you go from the MM to the MMM, you can simply gear up for more speed as well, since it won't get as hot.

I think (I hope) the most noticeable difference is going to be how smooth it is. No cogging or hesitations with a Neu motor. That would make me happy.

I think it would help a great deal.

I want to get the MMM when it comes out and I plan to run it on 5s, but what do you guys think would be best. the 1y or wait for them to come out with the 2.5d. Im leaning toward the 2.5d, but I have trouble waiting.

oh this is in an 10.2lb(no batteries) erevo.

Right On The Nose.
 

Drknow65 is exactly right. you can discuss this until the cows go home, and the only one who will really be able to see the difference is the one installing the new MMM and runing it. Yes the speed may not be a great deal better, but even so it will run faster and cooler and also longer run time wich over all is a better deal all around. Plus you won't have to push the MMM beyond its capabilities in order to get a good run out of it, hence it will hold up much longer. So the benefits of installing the MMM over the MM will definitely be worth the extra $$$.:lol: So your point is well taken and understood Sir. Good thread.

Thank you all for the comments!!!
