with my older Meepo ESC, i dont hear anything coming from the motors. had to change ESC because the Meepo ESC was stuck at 6mph. couldnt go any faster no matter what i did.
how can the Hobbywing ESC make my motors produce weird noises? did i get a defective ESC?
My backfire hobbywing makes a buzzing sound at idle through the motors. Its a good white noise machine to go to bed to.
Probably normal if its runs as expected.
