|  brushless question....
I know that brushless motors arnt generally used in crawlers due to there low speed short comings. However I am running a wheely king trans and was wondering if I put the gear reduction unit on it, which comes out to 174:1 drive,will that let my brushless turn enough rpms to work smoothly?

Short answer is, it depends. On alot of things actually. Post up the setup you're planning on running. There are alot of knowledgeable people on this site. And welcome  Also, this prolly belongs in "electronics" |

Brushless is the preferred motor in the Losi Comp Crawler but that is worm drive. The biggest problem is cogging and that is easily solved by running a sensored motor. Non-sensored would NOT be the way to go.

i think you may still be cogging even at low speeds... this is why sensored brushless is preferred all the time for crawlers  if you have a sensored brushless system, you will have no issues whatsoever. but you may get a little bit of cogging at very very low speeds. |

Sorry for the noob question but what is the difference between sensored and non sensored? How do I know which one I have? Thanks again for all the help. Also I have a brushless motor, wheely king trans and axial axles. Thanks again |

Sensorless, is like a guessing game.. It just gives power according to how much it thinks the motor should get, Thus, causing the motor to have no idea how much RPMs should be applied, as well as where the shaft is at, causing uneven low speeds. Sensored (has an extra port on the back)  Sensorless  | |

Oh OK. What I have is sensorless..... maybe I should try to trade for a brushed set-up. Any suggestions on a good reliable brushed motor and each? thanks for all the |
