over heating?

[ka1fornia]

so I was playin with my wraith today and my motor was so hot I couldn't touch it. I don't understand how it is over heating. My current set up is:

HH brxl esc
HH 35t expert motor
2s lipo 5000mah
spur is 80t
pinion is 17t

I think my gearing is fine but I could be wrong.
my only guess is that the motor needs a rebuild. I've been using the motor for 6 months now. That is all I can really think of. Also my gear mesh is fine and I have not added any wheel weights. Let me know what you guys think. Thanks

There going to ask, what kind of wheeling are you doing? Crawling, trails, mud, etc.

[ka1fornia]

Seeing as it only goes about 4mph max speed it's mostly crawling but I do trailing as well. I'm thinking because it only goes 4mph when I am trailing or trying to hill climb a little the motor is at max rpm for so long because it's so slow...

I just ordered an 87/15 and I will be running the stock motor for now. I am curious to see how slow it is going to be.

[ka1fornia]

that is going to be pretty slow, before i bought the HH 35T expert i was running the stock 20 on 80/17 and it was probably about 5-6mph. your gear ratio will be higher though so will be slower. It's awesome for crawling but i'm a little tired of the slow speed now...been running this set up for 6 months or so now...maybe longer

[Scott410]

Yea, I figured it would be real low.

I over heated my motor doing some crawling the other day , so I figured I would get some crawling gears and play around. I can also see how the 80/15 combo does, 80/20 is just to high for what I like.

I doubt anything was wrong with the motor in that short of a time till you got it hot. Your geard for around 4.7:1 and you need to be closer to 5:1-5.5:1 to stay cool.

I run those motors in 3 of my scalers and they usually last 2-3 summers before needing a rebuild and I subject them to a little water every now and then.

The thing is it just started over heating and i've had this set up for awhile without any problems. Today I took apart the motor and cleaned it up with some electric motor cleaner. It was quite dirty in there so next time I go out I'll be checking temps again. I couldn't imagine going lower in gearing. Like i said it's max speed is about 4mph. I would die if i had to go slower haha! Hopefully the cleaning will help...time will tell. thanks friend..
