Motor and Esc questions. FRIED!

[Thrice4500]

I am newer to this hobby and learning the basics from help and learning the hard way.

Here are my questions:


I have a axial wraith spawn. I put in a 17t pinion with a 550 size titan 12T. "For fun" and to see what would happen.

Here is what happened.... It was fast, decent torque, good top speed and seemed to be decent in the crawling speeds (no or little cogging). I never crawled anything super technical.

I was simply reversing away from an obstacle and it just quit. I have forward throttle only and no control its on or off. NO reverse. AAAAAND it goes balls to the wall with the ESC OFF..... Hmmm. Steering works still..



I know the ESC is fried... Its the axial AE-5 from the RTR kit.



Now.. explain to me why this happened, what i could change. I assume i just overloaded the ESC somehow...



In addition.... I want to go brushless but for crawling i get confused on which systems would work for good speed AND crawling without frying..


RCGEARSHOP.COM has my price range... HELP before i spend money for no reason!

i would start with trying to recalibrate the esc, id go straight to brushless because i like the power and the maintenance that almost never needs to be done to it. But if your on a budget, Hobby king x car 120a esc has some good reviews, i used the hobby wing which is nearly quadruple the price, one lasted a while and the other took a dump after updating it, but if your happy with the brushed, why not keep it with a cheap esc for now until you can get some high quality stuff like tekin or mamba that will last until your sick of the hobby

Did you run 3s? The turn limit on 3s is 18t, on 2s is 12t. Sounds like you need to recalibrate.

What were motor and esc Temps? 160 on the motor max and appropriately 120ish on esc. If you go brushless get a sensored brushless combo that is programmable. I would say 13.5 17t range may give you the speed and torque you need but I'm conservative so. Most brushless sensored stuff in not waterproof so keep that in mind. Holmes hobbies will waterproof his sensored brushless motor boards. Good quality stuff.

If your esc is newish call axial and tell them it kicked it. They warrantied mine cost me shipping the dead one in.

is too hot and it burned,maybe for too many turns of the engine
