Default brushless endbell timing and rotation

hey all, just wondering if it matters to a brushless motor, which direction it rotates for forward drive, when you can adjust the timing off the endbell, i know it matters with brushed motors so i was curious if brushless was the same

also, can you run the same motor, in reverse rotation, with a sensored hookup?

Yes timing is dependent on rotational direction of the motor. However you can run it in reverse but if you want to add timing you would have to retard the timing on the can. You can also run it in reverse with the sensor cable.

ok, so if i zero the endbell, the motor wont care about running in reverse rotation and adding esc timing?

I read that Not all motors are apparently 0degrees when actually set at zero, but someone else will know the answer for sure.

I dont think that the timing would work from the esc if you just reverse the direction. Like the motor timing it is directional, and some features are based on rpm. If you reverse the singal from the radio (like i think you would be doing) I dont know if the esc would regsiter that and retard the timing for the reverse direction. Some may, but im not sure how you would check if they do. I have never run my buggies backwards fast enought to really tell if there was any timing from the esc.

im not running in reverse...and im not reversing the direction from my radio, im trying to figure out if its safe to run a brushless motor with timing in its reversed direction, with the timing set to zero.... than if i could add timing to it from the esc

the rotation of my gearbox is reversed so in order to go forward, the motor needed to be in "reverse" rotation....

Yes that's what I meant. How would you reverse,the direction of the motor without reversing the signal from the radio?
