Sensor Wire Question
Ok this may sound like a dumb question but please enlighten me...
I'm still learning all about the brushless setups after being out of the hobby for many years....I just got a Maclan Pico 1/10 Sensored ESC and I have a Reedy S+ 17.5t motor. I just realized there is no sensor wire that came with the motor or the ESC. The ESC does have a mode called "Full Sensored/Smart Sense"....with smart sense mode it allows you to run a sensorless motor or in the event of a sensor wire malfunction.
My question is, do I really have to run a sensor wire? What are the pros/cons and if I should run it, does it have to be a specific type of sensor wire for this particular motor? I'm about to install my electronics tomorrow along with a Sanwa RX-482 receiver (MT-S Radio). I want to make sure I'm doing this all right the first time and not learn a costly lesson later.
Thank you!

Not all sensored ESC's can handle a non sensored setup.
A sensorless setup is basically also sensored but then the coils of the motor will sense the position of the magnetic rotor. Problem with that is the rotor need some rotating speed to produce a high enough voltage pulse in the coil that can be read by the ESC. That is why the motor cogs when you want to drive slowly away..
Sensored setup will move the detection to so called HALL sensors (electronic magnetism sensors), they do not nee a small rotation speed to sense the rotor and can even sense the position when standing still.
Sensored will give a more smooth start and control over the motor. And you can mechanical adjust the timing by rotating the sensor board whil with a sensorles it can only be done within the software of the ESC.
