Hi, I just wanna know about coreless motor. What's the differences with stock motors.
Thank you.

its a 180 class motor and it basically has no core. the center of the arm is empty. it reduces rotational mass and it says that it produces 2-3 times more torque than other mod motors of the same size. the motor also extends battery life byy a lot. some person told me that with one motor that was slightly slower gave him 35 mins on his battery pack and the coreless gave him an easy hour of the same bashing. i still have mine but someone told me they are slow. i think with the extra power you are suppose to gear some more speed to the car, just like you do when you add neo-mags

oh and this motor was made for an 1/18 scale rs4-micro and or that new 1/18 xray

Thank you, Anthony.
Do you have any inside pics about this kind of motor?
I got curious about "basically has no core. the center of the arm is empty".
