Hello Andy, first of all: "Yes", that is possible. The 2.4 GHz control systems do not all use exactly 2.400,000,000 GHz, but are distributed over small frequency sections, of which there are many authorised ones. Unlike earlier 40 MHz or 27 MHz control systems, where each individual frequency, also known as a channel, was generated with plug-in quartz crystals in the transmitter and receiver. One receiver and one transmitter had to be fitted with the same channel number and it had to be noted which belonged in the receiver and which in the transmitter. The 2.4 GHz systems usually handle this communication themselves or after synchronisation is called up using a pushbutton. These are usually protected against accidental pressing. Once synchronised, both the transmitter and the receiver remember who belongs to whom. Only renewed synchronisation changes this. This means that 2 sets of the same type can be operated side by side without influencing each other.

Yes, you can.
