i have hesitation with the motor, its my 1st time to use Speed passion with my elec.
my question is when im running with sensor wire the motor is making sound just like a whistle, but i dont see any problem with the motor performance,
but when im running without the sensor wire there is no whistle sound, is it normal when im running with sensor wire?

by the way my esc settings is default setting according to esc manual,

and i also connected all wiring connection properly.

thank you.

I actually noticed the whistling with one of my motors a while back,it turned out to be a shot bearing,so I replaced the bearing and no more whistling,but,your sensor wire thing has me stumped.
Try oiling the bearings and see if that helps,and the only thing I can think of without the sensor wire connected,the motor wouldn't be as fast,thus no whistle from the alleged bearing?
Hope this helps.
