Default Brushless making noise?

I just got my mamba max, BM9 brushless installed and it is making a constant squeaking noise, Is that normal? The noise is speed biased and increases. Any ideas or is this normal?

Hi, as far as I know it is normal for brushless motors. The rumor depends on the way the ESC (any ESC) gives throttle to the motor.

It's not just mamba - my Quark33 makes as much noise as my mamba.

The motor sound is one of the tools I use to hear how hard the motor is working, if I get in a bind, I know when to let off before breaking something.

ok, thanks for the info. I'll play with it this week and see. I have NiMH on it now but will change to Lipo this week.

That is one of the differences between sensored and sensorless
