{Noob Question} Does the lower the kv on a motor mean more torque or opposite?

Thanks

Lower kv more torque, higher kv more rpm/ top speed less torque.

Short answer......No....
But the KV does effect power. Just not torque.

I read that lower kv was more torque, am I wrong?

Have a read of this...

The turns of windings in the motor determine how much energy is dispersed so a 6t 5000kv 540 sized motor can take 11.1v but a 3.5t 540 cant because the power has shorter travel resulting in over heating but thats where the torque comes in been able to run higher voltages in lower kv motors because it compensates amp draw with voltage and the higher kv motor will do it with less volts and more amps.

So in my scx10 if I go to a 20t motor then I dont lose torque for crawler but I do gain wheel speed?
For whatever reason even after reading that I not.understanding. Ive always thought with the higher turn the more torque bcuz it holds more energy to turn it?
Sorry for being so dense im just not understanding.

that does not make sence?? Don't u mean power not torque? VxA=power

In a way that's irreverent. There are a few variables.
but if the motor size and voltage remain constant there on no torque difference in torque but there is a difference in power.
after all power is torque times RPM so if the torque remains the same but the rpm changes then there is a difference in power.
