Disadvantages of brushless motor：
1, friction, large loss
Old friends when playing a brush motor before encountered this problem, that is to use the motor for a period of time, need to brush, open the motor to clean the motor is time-consuming, less maintenance strength a family cleaning.
2, fever, short life
Because of the structure of motor with brush, brush and commutator contact resistance is large, resulting in the overall motor resistance is high, easy to heat, and the permanent magnet is a sensitive element, if the temperature is too high, will make the magnet demagnetization, motor performance, influence of brush motor life.
3, low efficiency, low output power
The above mentioned brush motor heating problem, largely because the current work in the motor internal resistance, so there is a great degree of power conversion to heat, so the output power is not the brushless motor, the efficiency is not high.
Advantages of brushless motor：
1, no brush, low interference
Brushless motor to remove the brush, the most direct change is that there is no brush motor running when the electric spark, which greatly reduces the spark on the remote control radio interference.
2, low noise, smooth operation
Brushless motor without brush, the operation of friction is greatly reduced, smooth operation, noise will be much lower, this advantage for the stability of the model is a huge support.
3, long life, low maintenance costs
