Will a RC transmitter and Receiver from different brands work as long as they have the same MHz?

In general, a radio control (RC) transmitter and receiver from different brands can work together if they operate on the same frequency (MHz) and use compatible modulation types (such as FM, AM, or digital protocols). However, many manufacturers use proprietary communication protocols, which means that even if the frequency matches, the transmitter and receiver may not communicate effectively. It's essential to verify compatibility specifications from both brands before attempting to use them together.
