I picked up a firma 130 amp ESC and was looking at this motor on Amazon

Spektrum Firma Brushless Motor, 3150Kv, 4mm Bullet, SPMXSM1000​

Would this be a good fit with my ESC? I’m not looking for anything radical my main objective is to run a larger pinion gear than stock and not overheat the electronics. If it goes a little faster that’s an added bonus but not my main concern. Also looking for some thing that is more plug and play and not wanting to swap out connectors on the ESC. Last question is my stack big rock has a motor fan and it looks like the wire to plug that fan in is not included on my new ESC. Thank you
 
that’s too high of a kv for running 4s, especially if you are planning on gearing up. Look for a motor in the 2200-2400kv range for running on 4s
 
That seems like it would be a lot of torque for a 3S truck. If I get that low of a KV rating and gear up when that be about the same as keeping what I have now? I’m new to this and trying to understand how this works. Thank you for your response
 
Cheap ole 3665,3670,3674,4068 all work good..I like the 4068-2650kv
