ESC getting hot
I have a stampede with the Xl-1 esc(which is crappy, i know) and just upgraded from the stock Stinger motor(20t) to a Speed Gems Arcornite 19t. The Xl-1 now gets ridiculously hot, but the motor and batteries are not very warm. I have it running 18/87. So what is the problem? I am new so anything will help, thanks.

RE: ESC getting hot
No, the motor does not get hot. What might I switch to? A 17t pinion? Or should I keep going down until the heat starts to go away?

RE: ESC getting hot
Ya, try a 16 or 17 tooth to see if that helps. Also make sure nothing is binding in the drive train and that your gear mesh is not set too tight. How hot is it getting? Is it too hot to touch the heat sinks and hold your hand on it?
Sorry, I just noticed that I missed where you said the motor wasn't hot in the 1st post.

Oh yeah, the gear mesh is the spacing between the pinion and spur gear right? Yeah, I'm pretty sure it's properly set up, with just a little wiggle room in there.

RE: ESC getting hot
if the motor is not hot then its not really geared wrong. An esc can get hot with different motors. Ecpecially going down in size. The esc has thermal protection against heat so if it were to overheat it will cut off till it cools down but its not good to keep running it hot time after time. It is capable to handle down to a 17t standard motor but the 19t that you now have is a modified motor. The esc cant handle a modified motor because of the advanced timing. You can use the xl-10 esc that can handle down to a 10t motor and even modifieds.

RE: ESC getting hot
So I have to buy a new ESC, great. When looking at ESC's will it specifically say whether or not it can handle a modified motor? What is the different between modified and not anyways? Thanks.

RE: ESC getting hot
It has to do with timing. Standard motors have 0 timing. Modifieds have advanced timing. Most are advanced more than 10 degrees. It would be cheaper for you to get a different 19t motor. You can get a 17t double wound motor way less than a new esc. A 17t will get you down to the esc limit and the double wound gives more torque to compinsate for gearing and larger tires. Rule of thumb is to keep your pinion 2 teeth lower than the turns of the motor you are using. So if you had a 17t motor you would need a 15t pinion. A double wound is better for the larger tires and taller gearing. A single wound motor will not have as much torque but will have a better top speed. If you want a good cheap motor you can go with a fireball 17t double. Speed gems also have other motors that are standard but with double wound.

RE: ESC getting hot
I was just trying to recommend the cheapest way to bring down the temps. Gearing down will help the ESC to not have so much load on it, but the best way would be to get a better ESC.

Yes regearing would help but then that pretty much makes the motor change useless because you will lose the speed that you wanted to gain in the first place. I think the cheapest thing at this point is get a standard double wound motor and sell the one he just bought. A better esc will cost up near 75.oo. A good motor will cost about 25-30.

Hey for $3 for a different pinion it's worth a try before swapping motors or the ESC.

RE: ESC getting hot
Will my speed improve any with a better ESC? I don't mind having to upgrade it, although I wish I had some of this information before I made a poor purchase.

Yes true. My sons stampede has a trinity speedworks caliber 14t double wound modified with heatsink, robinson racing spur, steel tranny gears and the traxxas xl10 esc. Talk about fast. It would keep breaking the rear axles so I installed Jato axles and have not had a problem since.

RE: ESC getting hot
Well I probably just go ahead and get an Xl-10, something I was going to do eventually, just didn't think anytime soon. The Arcornite performs decent enough and I have not messed with the timing yet, so I should see some improvements. The Xl-1 just gets too hot. I did not know about the HZ things. Thanks for all the info.
