As you can see, we have a new forum to discuss brushless RC motors. One reason for this is that over the next year or two, brushless motors will become a much bigger part of RC. That means many members will need advise or be able to offer their experances with them.
Second reason is that I recently purchased a Novak system and got a chance to race it this past weekend. All I can say it that it will really be hard to go back to a brushed motor.
While I've had limited exposure to brushless motors (run one weekend in offroad) I can say I feel they are smoother then comparable brushed motors. One other thing I noticed is that they don't seem to have that huge torque from low speeds, it takes them a little while to come on. That's not all bad in offroad. I would compare it to running your brushed motor ESC current limiter at 50 amps or so.
All in all, it was a very good experence with my first run with the Novak system.
