Electric rc motorsWith technology continuing to develop light-weight and more efficient power supplies, it’s not surprising to see an increase in the number of electric powered rc airplanes, helicopters and gliders. Combine demand with continuing drops in cost, and you soon realize that electrics are a great way to get into the world of rc.

Additionally, take a look at trends in the rc industry. Demand and adoption rates of electrics have been sky-rocketing especially with brushless motors which are now eclipsing older brushed technology. This isn’t to say one is better then the other (though some will attest). They both have their place in the rc world. Regardless, more rc pilots are looking into today’s electric technology as a clean and powerful alternative to fuel driven engines. So what’s the big difference between brushed and brushless motors? In a micro nutshell, here are a few key differences.

Brushed Motor
  • While durable in construction, they are less efficient then a brushless.
  • Have parts that will need to be replaced from wear but, are cheaper then brushless motors.
Brushless Motor
  • While efficient, they are less rugged, more complex, and more expensive the brushed motors.
  • Provides more torque and has a reduced noise level.
