I wanted to get a 4000KV because I thought it would be faster but a guy told me on another site to get a 2000KV and hasn't explained why. Can anyone here tell me why I should get a 2000KV motor instead of the 4000KV?

What are you putting it in? Lower kv motors are more efficient.

Can't put a 4000kv motor on a 1/8 truggy, don't even try. Castle Creations recommends the 2200kv motor for monster trucks and 1/8 truggies and the 2650kv for 1/8 buggies.

If you own a 1/10 brushless truck you know that you don't want to run a 7700kv motor in it or it will really overheat because you can't gear it low enough. Same thing here.

Have you ever tried starting your bike in a high gear? Almost impossible.

You should be able to put more volts through the 2000kv and run more efficient too and it should stay cooler.
also i would imagine gearing would be easier on the lower kv motor.

Lower kv is definitely the way to go.................................like a mamba monster 2200kv or possibly one like this : http://www.hobbycity.com/hobbycity/s...hless_Inrunner

I would not tell you to get a 2000 vs a 4000 withiout know some more info. If your gearing or voltage is low enough and/or your desired speed is high enough the 4000 is the best choice. It depends on your specific set-up.

Here's a nice calc to decide which is best for you. http://www.scriptasylum.com/rc_speed/_top_speed.html

Unless you're running on road exclusively I can't see the 4000kv working at all in a 1/8 truggy. Running through dirt and grass is harder on a motor and a higher kv motor will heat up faster at the same voltage as a lower kv motor.

Like I said, put a 7700kv motor into a 1/10 4wd buggy or truck and you'll run everything too hot and you can't gear it low enough.

OK I am gonna try to get a ez run 150a with 2350 KV motor. It comes in a package deal. ALSO does anyone know where I can find motor plates so I can add a brushless motor by the spur gear? I saw this and it LOOKS like it can fit but I dont want to be the one to buy it and then my diff starts rattling because I didn't research it. I am not afraid to hack up my chassis BTW.

You never actually stated what 1/8 you're going to put this in.

Maybe fab a custom mount troop that way you can get it to fit perfect.
