kinda in the same route there... getting an electric kit. its good to have more options to play with...
electric is nice since there's an indoor track but only allows electric kits to run - no more worries about rain or shine..
others may give you better insights but my best answer to your question:
- brushes in brushed motors are required to have contact from your supply or battery to your commutator. with power delivered to the commutator thru the brushes, the armature can now produce the magnetic field which can turn the whole rotating assembly thru its axle - this is with the help of the fix magnet at the case.
the brushes have a slot relatively stationary with the motor case with a spring pushing it towards the commutator. and since it is in constant contacts with the commutator which is part of the rotating assembly of the motor.
brushes tend to wear out upon use since friction (plus heat) is constantly applied on it while motor is turning.
sorry for the long post but hope you get an idea...
