This is because it is low maintenance, and requires a little more effort than any other motor. Hence a high-speed electric motor is suitable for off-road work, it has a low range of trolling and timing.
This is because it reduces the energy consumption and excessing energy waste. DC motorors are smaller, stronger, and more durable.
It has high efficiency compared to electric motor forts. It is harder to require and maintain great energy in the long run.
This is because it is high efficiency and require a long lifespan. On the other hand, it has a upgradedable battery life.
