I haven't been into RC in 6 years, and am just now getting back.... Yeah!~ So, with this brushless stuff... what do these numbers MEAN? I know 17.5 is like 27turn brushed, 13.5 is like 19 turn etc... but the numbers are?

thanks!

Originally they claimed that the brushless number represented half the number equal to a brushed motor. So a 13.5 was supposed to be the same as a 27t.. but as we found out early on, a 13.5 was much much faster. A 6.5 motor, one of the most popular for offroad in my opinion is more like a 9t brushed than a 13t. Another way they rate them by KV value.. this number multiplied by the number of volts applied is the RPM the motor will yeild.

Thanks Jerome! so the numbers are almost arbitrary... I asked the question at my LHS today and they had no idea. Long live rctech.net

I would have to check but I think a 13.5 would have 13.5 turns of wire on each pole in the can. Like I said I would have to check. So the number does mean something just not in comparison to a brushed motor.

just look at em like u did ur brushed stuff, just a different scale. soon comparison to brushed will be gone b/c ur only real reference pt (save for 540 can racing) will be brushless motors.
