Crawler Motor " T " rating better south or North ???

[Tread Well]

Well still a newb ! I was thinking the " T " to go smaller the better for crawlers like 19T motor is better than 27T motor.Am I wrong to think so much in black and white? I am seeing some super / expensive builds with " 45t " , " 55t " motors. Whats the deal? Going south is better or north is better? Thought higher the turns faster the vehicle but lower on torque and vis a vis.Still have'nt got a grip on these.The moment you think you understood somthing you have more questions.Please help me understand this.Thankyou.

The more the turns the higher the torque, but slower speed. The less the turns the faster the motor but has less torque. That is why most on road cars run 20t and under.

Hope this helps

Just remember big=slow, that's how I used to remember when I was new at this great hobby.

+1......if looking at brushless, it's a KV rating (what RPM/volt of power) where the lower the KV the slower the motor (thus reverse of the brushed).

Low "T" brushed is like a high KV brushless, better for fast rigs.
High "T" brushed is like a low KV brushless, better for lower speeds & more torque.

A lot of crawlers end up around 35T brushed, it's a nice compromise between wheelspeed & climbing torque.

What's said above applies (mostly) to top speeds at a given voltage feed.

High turn motors are also more efficient, which means that at a given power output they use less current and run cooler.
For a crawler motor that often run at higher loads it's beneficial to have high efficiency.
If you want more peak power too, to get more top speed, just add more voltage!

13t Crawl master fromholmeshobbies.com best brushed motor I've ever got to run. It on 3s is more than plenty anything. Has it all, speed, tourque, wheel spinning power.
