How do i change the RC frequencies?

I have gotten a RC helicopter from a friend but it has no controller and the IC chip is soldered in and the frequency is 40Mhz . So I was wondering how I can change the frequencies from one controller so that I can use it on my helicopter.

If you can get a 40 MHz transmitter the transmitter and receiver is not exactly 40 MHz

A 40 MHz transmitter and receiver need to be tuned to each other one or the other will need an inductor or an adjusted capacitor adjusted so they will receive or send the right signal.

On this RC receiver it is the inductor in the box.

Use a nonferrous screwdriver or Alan key to adjust the ferrite core until it receives the signal from the transmitter. (Nonferrous is nonmagnetic, most tuning keys are made of plastic.)

it is a Dongguan jiayi S006 Alloy Shark. I think that's that's brand.
Fortunately for you these kinds of things are parted out regularly. So the transmitter itself can be found for under $20.
