Hi Guys,

I can shed some light on the differences between sensored and sensorless esc designs.

Essentially, sensored designs are old technology. There is a Hall sensor in the motor (wasted space) to provide information as to motor position to the controller. The problem there is, that there is NO flexibility in how the motor is run. You cannot adjust the timing as a programming function, and to be the most efficient and powerful, the timing needs to be adjusted on the fly - not possible in a sensored system. Braking also suffers in proportionality as well.

A sensorless esc (which will run either type of motor) relies on the back EMF of the motor, as interpreted by the software, to know where it is. Basically, the better the software, the better the controller's "feel" to the user. This also opens up nearly every aspect of how the controller works to adjustment and tweaking for your personal set-up. Timing advance, brake strength, PWM switching frequency, throttle curves - you name it, it can be adjusted. The best sensored controller is always not as efficient as the best sensorless controller. And in electrics - efficiency means heat generated from wasted power. The motor will run cooler with more power, and the controller will run cooler as well (and be smaller with no need for heatsinks).

i think youre have to get a 8t hacker to compare to a 10t brushed the hacker will have about the same speed(at 6cells) but will more torque then the v2

Shawn

All that you said is very true but i have yet to see a sensorless system with a throttle as smooth as the novak.Im sure that sensorless will eventually take over(maybe) but imo its not there yet for 6cell car use.

Mike Mayberry was running some kind of brushless setup in his micro, definately fast, maybe even overpowered.

Brushless motors are new to R/C, not the rest of the world...

I think Mike's car was very much over powered. He flew down the straight but couldn't seem to get the handling down.

I was gonna ask how it worked, glad you like it. Spread the word, maybe I'll become the electronics supplier to all the RC community

We'll get you a good commission check Every one! If you live in San Diego and need a TV, go see Randy @ Sears in El Cajon! (How was that? )

Hello !

I am thinking of pruchasing a brushless sytem and want to run it in a XXX-S or a TC3.
I hav not had any contac to brushless systems so I thought for the beginning it would be easy to buy the novak system.
What are the alternatives to this system ? Is there something cheaper, better, smaller ???
