Default Sensored VS Sensorless motor

What is the difference between sensored and sensorless motors. Is one better then the other. I'm I gonna see that much difference between the two that I should get the sensorless motor. I have a few sensorless motors and now but I have a chance to pick up a sensored set up for a reasonable price should I buy or stay sensorless set up. Its a duratrax 17.5T sensored motor and hobbywing 60A sensored ESC for about one hundred dollars brand new never used.

You are getting what you are paying for with that unused 100 dollar setup

Sensorless only motors are usually made with heavier rotors that are a little slower for the input power.

Sensored motors can offer more timing options than sensorless. Sensorless motors take timing measurements via software. Sensored motors take timing measurements via hardwire sensors. I prefer sensored

For most "faster" applications, you probably won't notice the difference between the two. You will notice a difference at slower speeds, the sensorless motors will start cogging on you, so if you run on a tight track (or especially in a crawler or Wraith type application) you'll want to go sensored.

I run sensored in my Wraith, but sensorless Castles in my Slash and Rustlers and have no issues with them.

They both have there advantages, in most applications a sensord motor is smoother and can be made faster than its sensor less counterpart. But generally sensor less set ups are more efficient. In mod or open classes I prefer sensor less. But in a boosted 17.5 class a sensor less 2400kv couldn't hold a candle to the sensord 17.5

A real 1409 2400 kv nue motor would be faster than a17.5 sensored boosted or not.

Il be honest i like sensored motors better than sensoredless after running my 2wd slash the sensoredless seems to clog from a stand still more ive noticed from running them.

I can find nowhere where any useful information is given about these Neu motors. They are sensorless if they are Wye wound

How much would that real NEU be compare to the 17.5T?

sensored >>>> sensorless any time, unless you just bash

I did many testings in 1/8 and 1/10 racing applications and sensored provides a better feel and performances, much smoother.

I agree with you.

Sensored is also able to give larger amounts of timing. If the software is programmed correctly, the sensorless timing will be more precise up to the limit of timing that it can apply, but the Sensored motor will out time the sensorless motor and thus be faster overall if set up correctly
