Hard wired controllers

Hi!

I require your help regarding a problem I’m encountering.

How do you change a hard wired controller to a wireless rc controller

Thank you so much in advance for your help!

You replace the wire with a radio.
To get a more specific answer you will need to ask a more specific question.
There are various types of radio control (rc) transmitters and receivers that can be used. What you need and how you do it depends on exactly what you are trying to do.
