Brushed motors need comm cuts and brush replacement every 5-10 runs.

Brushless just need a good oiling every now and then.

Plus brushless is more efficient. And can go real fast.

No.
In the long run its cheaper. Esspecially if you get a comm lathe for the brushed motor.

will there be a decrease in power when the brushes wear out in the motor?

okay, that explains why may electric cars seem to be getting slower as the day goes by [&o], thanks for the help
can the speed controller in the e-revo handle brushless motors?

I know it depends on the car, but about how much does the brushes cost to be replaced every 5-10 runs?

No, the speedo in the E-revo is a bog stocker EVX-2 for the two brushed titans that come with the E-revo.

Brushless motor ESCs are totally different to Brushed ESCs as the motors work differently. However brushless ESCs sometimes work with brushed motors, Castle Creations MM esc for example, will run both brushed and brushless motors. However it requires the ESC to be set in a different mode, and failure to do this will destroy the ESC.

Brushless ESCs are far more complex, hence the reason brushless ESCs are almost always more expensive than brushed ESCs, and hence the reason that releasing an RTR brushless vehicle is a big deal.

ok thanks for the help, these brushless motors may be the nail in the coffin for nitro.

Brushed is cheaper to run but expensive to maintain...need a comm lathe

Brushless no comm lathe needed, and the motors last a while, the only thing you need to replace is the front bearing every 300 runs.

Default RE: brushed VS brushless motor

yeah the reason i am asking all these question is because i am debating about getting an e-revo when it is released but i hate the titan motors they put in there. I really do not want a mamba max or Nue motor because i can't spend that much money[:@]. Will the side winder work for that? i really do not care or want anything to go above 30 or 40 MPH. i am driving in parks or my yard most of the time so anything above 40 is over kill.
