Default Noise in the Monster Truck

Hi all,

I am Vic. This is the first time I play electric RC car.
I bought a HL mad truck. The problem is when I press the throttle on the controller, the car starts to move but there is a noise coming out from the car which sounds like Yeeee~~~~, sort of high pitch electricsl noise, it is disturbing. Release the throttle and it is gone.
The noise is similar when I press on my 12V electric cordless power tool.

What is the problem ?

Thank you,

Regards,
Victor

It might be the transmission OR in the gear mesh on the pinion and Spur.

It is sort of electrical resonance noise which resembles those generated from old ceiling fan speed controller, Any expert Advice ?

Thanks.

NB: It is a 1/10 monster truck.
