High pitch whine noise, ack?!!

[Robbob]

maybe im tone deaf but in all the years ive raced and using almost every ESC out there, im yet to hear a whining noise come from one.

got a brushed Mamba and mines quiet, nothing coming out of it thats annoying.

but it cant be as bad as some of these brushless motors ive heard in crawlers. not thats an irritating noise, it makes me just want to push the drivers finger full boot just to try and get rid of the squeel. :lol:

some of the newer lowend escs(stock axial,tazer,etc) are pretty quiet but every novak and tekin ive ever had make the high picthed whine at low speeds way back in the day it drove me nuts but now i dont even notice. to me it was always kind of like a ford leaking oil it it doesnt do it something is wrong

My Tekin FXR-Pro's don't make any noise

x2 Confirmed. All I hear is transmission and servo noise. ESC is totally quiet except for the beeping it does on startup.

So only one person has a quiet ESC?

How about the BEC theory, anyone running that and notice noise or not?

my goat is quiet with cc bec but hitec 5995 whines.
