Overgeared vs. Undergeared - Thermaled ESC
#35
Wow anyway.... LOL
That gearing is fine on that vehicle.. LOL don't change it unless you want to.
#1 Check the fan on the MMM, it should kick on when you first start up to verify operation, if it doesn't spin up get a replacement.
#2 Check connectors (solder joints specifically) between your ESC and battery most likely
#3 Lipo condition? Make sure you pack is up to par for what you are doing.
#4 Refresh your MMM software, update if not updated, reset to stock config then dial in again.
After those are done come back :P

Well I wouldn't go that far,, in fact that motor is rediculous overkill for a 1/8 buggy, a 550 4pole or 36x60mm 4pole is all you really need (save weight and increase run times). That motor is almost overkill for a truggy even, but with out a doubt it will be flawless on either a buggy or truggy. The prior pages of arguing are really about mute as the 2200 1y is super effecient and could can run most usable gearing options you can fit.. 12t-18t easily. That said you have to make sure you are geared properly for your track to maximize run time and lap times.

With out knowing this guy he could have a "nitro finger" and maybe overheating the ESC from that, constant blurps with amp spikes ESPECIALLY if it's not a top quality lipo can be very stressful. Even this is not likely to cause a thermal, but when combined with a fan not working properly.. it's a sure bet.

Are you saying that if I ran a big v8 in a mini cooper it would some how over heat because there is too much power it's too easy to move from "a" to "b"? That's not how it works.. you can have a ton of issues but having too much motor isn't going to be your issue. Wrong voltage, wrong Kv would be the top two, but in this case he's spot on so it's got nothing to do with the motor or gearing choices.

Yes I do have a nitro finger.
The 2200 motor is great when treated with respect. Been running one for the last 3 years.
The software is the latest.
It has plenty of airflow.
All connections "seem" be good.
This is an entirely new setup for me.
I believe that I am slightly overgeared. I need to retrain my throttle finger. I suspect the fan might have a issue. It runs when plugged in, but makes a little noise.
I appreciate all the input from everyone, even if everyone seems to disagree.
After the rain stops sometime in the next month, I will give an update.

BTW, A Tekin system is in my future, just not in my bank account yet.

All i have to say is what's already beed said. The ESC over heating and not the moter is the ESC not having enough AMPS available for it, The motor is too big or just plain not enough cooling.
If the ESC is under sized for the motor but the motor is not undersized/over geared for the truck you would get a hot ESC and not motor. Any way Good Luck.

Keep in mind 'hot' is relative:
Hot battery, hot esc, hot motor - overgeared
Cool battery, hot esc, hot motor - probably overgeared
Cool battery, hot esc, cool motor - probably overgeared
Cool battry, cool esc, cool motor - run it
Cool battery, cool esc, hot motor - probably undergeared
For bashing (and racing for that matter) with relatively steady throttle control, you should find yourself on average using 50% on the trigger/rpm of the motor. Speed runs don't count.
Hot battery, hot esc, hot motor - overgeared

Hot battery, hot esc, hot motor - overgeared and battery does not have enough C capacity of this which could also contribute to overheating on ESC
Cool battery, hot esc, hot motor - probably overgeared
Cool battery, hot esc, cool motor - probably too much motor
Cool battry, cool esc, cool motor - run it
Cool battery, cool esc, hot motor - probably overgeared.
This is as I understand motors and electronics.
