Hello, I'm new here on the forum.
I'm also new to RC helicopters.
I bought a second hand radio controlled helicopter and transmitter.
But I can't turn it on.
I launch the helicopter and then the radio transmitter, but there is no connection between them.
I guess there is a way to pair them but I couldn't find how.
I can't even find the model of my rc helicopter.
Thank you for your understanding, but I'm really barefoot.
I will upload pictures and a video of my RC helicopter.

Hi r_Osen,

The radio control (Tx)  is 2.4Ghz and Receiver on the Heli is 27Mhz. They are different hence they wont bind together. I am not sure is there is a way to do that. May be you should have a transmitter with same frequency.

I paid attention today too.
If I find a remote from some cart or helicopter and change the crystal will it go.

in a 2.4 gz transmitter there is no any crystal fitted . you need to find a 27 mhz transmitter with same frequency.

in 2.4gz there are so many different protocols & you will need to have tx & rx of same protocol.

If you are new comer to Hobby , I suggest to buy new things from reputed seller.

There is a 50% chance that it will work, if you find a same 27mhz remote.

Best thing to do is to take the heli to a toy repair shop, they may have these toy grade transmitters, which may work with your heli. Esky Transmitter is a good investment for now, don't feel bad about it. if you can arrange a ESKY receiver later you can use it on any RC model once you get into this hobby.

Hope this helps. Take care
