I just finished up a Gelande II cruiser build using an Axial AE5 ESC and a RC4wd 35T Motor.
I have a pretty loud high pitched motor whine that takes away from some of the enjoyment of driving such a scale truck.
I was going to try a different motor but after doing some reading it seems the PWM frequency of the ESC can also cause the whine.
The AE5 has a PWM frequency of 1kHz. My SCX10 has an AE2 with a PWM frequency of 6kHz with an Axial 27T motor and is much quieter.
Does anyone have any experience in how to reduce the amount of low throttle motor whine? Should I change the motor or ESC or make the biggest difference?
