|  brushless motors
can someone explane the differents between censored and censorless brushless motors and how to wire a censored motor

It's actually sensored and non sensored motors. This may help you out in your search.

Sensored motors use an extra cable (the sensor harness) to connect the motor to the ESC. The motor has hall-effect sensors built in that send signals to the ESC, so that it knows how the rotor is positioned, and which way the motor is turning as soon as it moves. Sensorless setups aren't really sensorless. They use back-EMF from the 3 windings to work out which way the motor is turning. When the motor isn't turning, the ESC doesn't know where the rotor is, so it doesn't know which way to spin the motor when you hit the throttle. The motor has to be spinning to generate the signals. This means that sensorless systems usually suffer from cogging (motor hunting back and forth, stuttering) when you pull away. Makes low-speed control tricky. Not good for crawling. |

so clockworks you would say that sensored brushless motors are better then non sensored ?

Cheaper Lighter Less to go wrong For aircraft, light weight and reliability are important, so all the aircraft setups that I've seen are sensorless. Low-speed running is pretty much irrelevant in a plane. For cars and trucks, driveability is more important than saving a bit of weight, so sensored is better. | |

reason why am asking i just brought a brand new trinity 10.5 for my brushless ESC with sensored input but the motor seems to do more shuttering then a non sensor brushless motor i have like my 5.5 has more torque than the 10.5 motor which doesnt make sence it has the same pinon i used or the other motor which is 21p
