When building models, be they planes or boats or robots, the ubiquitous motor of choice is the brushless motor. The reason for this is power and longer run times. A motor with brushes has current running through them into the center of the motor. After a time, friction can cause wear, resulting in the brushes needing to be replaced. The brushless motor relies on magnets to turn the rotors, causing little to no wear. Another benefit of brushless motors is the fact that you can upgrade the magnets on the motor, giving it more power.

Instructions
1
Remove the motor from its mounting screws. A screwdriver works well for this application. If it does not come easily, don't be afraid to use force.

2
Secure the motor in a vice and remove the rotor. Be careful not to damage the stator and the bearings. The stator and rotor are located on the back of the motor mounted on green card. The rotor is wrapped with copper wire.

3
Remove the existing magnets from the inside of the motor. The A screwdriver will work well for this application. Place the new magnets in their place. Secure them with epoxy glue. Let dry overnight before continuing.
