Biggest difference between sesorless and sensored is the response time.

Sensored motors are said to respond quicker, like when you start moving from a stand still.

Also, it's said that they have more predictable low speed and breaking.

But I haven't ever used a sensored motor, I just read about the differences when I purchased my brushless. So you might want to confirm the differences by talking to someone who has actually used both.

@Driftfreek, there.

The EZrun BL system is proven to be good.
Bad side is that it's a Sensorless BL. Mainly meaning it 'stutters' at low RPMs.
Precise throttle control may be a bit harder to achieve.

And there.

@Abdul
Have you noticed if your BL system stutters when at low speed?

Yeah... It does.

It's also nearly impossible to cruise on a slow/dead slow speed.

I used to think it's just my hand, but after asking other people on other forums (knock off alert!), I found it it's because of the sensorless motor.

Do the sensorless systems stutter off the line...... YES
Are sensorless systems difficult at very low speeds....... YES

Does it really matter for drifting .........I don't drift but I would guess NO
Does it really matter for racing .......... No, Not at the standard we race at very happy

Are sensorless systems cheaper to buy...... YES
Is a sensored motor combo a better system ........YES, but we are not Pro's here.

So unless you are a Pro and are looking for that little extra bit of performance to get that little extra edge against your competition, then just get the sensorless system. They are cheap reliable and will give you all the power and fun you need.

Gregs right the advantage for drifting and racing is minimal, the only place were sensorless will give you an edge is in rock crawling where you need the motor to be smoooooth at low power, and no motor cogging! very happy

I beg to differ with the first statement sir.
It does matter in drifting.
It's called "throttle control".
Not the "bang bang bang" and "trigger-happy" technique.
In drifting, the tires have more grip at lower RPMs. <----- Tip to those still drifting here.
You just need to know when to use it.

I will agree on the second statement.
One does really need to be 'immersed in the game' to understand the benefits and disadvantages of various electronics.
