Please read my comments about the PCB I have used. If you buy a RF Tx/Rx without a motor driver then you have to buy motor driver board separately and plug it into the RF tx/rx PCB. All in one PCBs are also available. Every RF Tx/Rx PCB look different as it depends on the maker. But they all work just the same. You just need to ensure that you get the one with motor driver in it or get motor driver separately and plug it. I will post another video on how to connect these, soon
