Default Are brushless motors faster than brushed?

i am curious to get back into 1/10 electric touring cars. i used to have a cheapo hpi sprint, and a bunch of minis. i have heard that a comm lathe is essential electric cars these days. i also hear that the maintenance of brushed motors can be frustrating too. we all know that if you put ANY brushless motor system in a 1/18 scale car, it will turn into a rocket and have incredible run times. i was curious to know if the same thing applies to 1/10 touring cars?

basically, i want to know if brushless motors are ridiculously faster than brushed motors in 1/10 touring cars too. i mean, do you really see the huge speed and power gain in 1/10 brushless systems as you do in 1/18? or is it mainly elongated run times?
thanks

It depends. There are some brushed motors that are still faster than brushless. The Novak 4.5 Motor and the Reedy 4 Star will be about equivalent or faster than most 7-8 turn motors.

So yes and no.

yeah get the 4.5 by novak or wait for the new mamba system

from what i have herd, the mamba for 1/10 will be better and more programable than anyother system

you can also hook it up to ur computer and ajust our rpm, and all that

The 1/18th brushless systems are much more powerful than their brushed counterparts because they aren't restricted by rules. They are also so much better because the 1/18th brushed motors are very primative compared to modern 1/10th brushed systems.

Non-ROAR legal 1/10th systems from Lehner, Hacker, Feigao, and others are very powerful. I wouldn't say that they blow away today's brushed systems, but they are very comparable with much, much less hastle.

I beg to differ. Have you tried a Reedy Mini Max, or a Beast mod motor, or how about Trinity's Cobalt? All have outstanding rip and top speed. Also they are just as tune-able as any 1/10 scale motor. I race with a brushed motor...by choice over the brushless. I will agree, they have ridiculous top speed, but I have yet to see one that is as smooth and controllable as a good brushed.

As for waiting for the Castle Creations 10th scale version of thier brushless system, I wouldn't hold my breathe. Its' release has been delayed for a long time now. Hopefully they are doing the right thing by fixing bugs in the system before it gets released to the public.

I raced this past Sat in Mod truck off road and I was passing a few of the other vehicals. I was using the Novak SS+ with 5800 brushless system which is 8.5 turn bushless. So that one is real fast. I have a GTB 5.5 I have not had a chance to race it yet but cant wait. It should be really fast.

ok, this is really clearing some things up.

when the brushless system says that it is 5.5, 6.5, 8.5, etc, what does this mean? is it the rating for the motors? is it like brushed motors, the lower the wind, the faster the motor?

i will be parking lot racing most of the time, and even when i do club race, there are no restrictions. i am looking for a brushless system comparable in speed to a 11-13 turn brushed motor. what do you all recommend?

also, are brushless motors any harder on your drivetrain than brushed motors?

#1a The number of winds...
#1b YES
#1c YES


#2 5.5=10
6.5=12
8.5=18 or 19

#4 YES

#5 5.5 or 6.5

#6 NO

thanks, i think i understood your answers. here are some more questions for you.

is it hard to control the throttle when using a brushless motor system? do they give you any more punch off the line compared to a brushed motor? do they heat up as much as a brushed motor? if i get a brushless system, can i go back to using 3300's and still get good performance, or do i still need to stick with the latest high capacity batteries?

sorry for the question seige, but you have piqued my interest.

#1 No , linear thottle is more predictable & smoother as well , not to mention it will always be the same, run after run, race to race...

#2 Will be the same as a "fresh" or "new" brush motor...

#3 YES, In fact , because of better efficiency, the 3300`s will perform very good ...

#4 Will have no problems using the newer cells like 3800 or 4300 ect....

Default Dang !

If you gear the motor correctly , Temperature`s will be similar to brush designs...

If you are asking is it mroe effiecient and will it produce longer run times with the same given battery capacity and setup to have the same or very equivalent power to the brushed motor in question?

Yes. They are more efficient and will run longer.
