need help for the spirit gt with aero firmware in conjunction with a graupner mx20 and gr 16 receiver. in the channel selection, i selected channel 5 for bank switching and assigned a triple switch to channel 7 on the transmitter.
However, I cannot control the free channels 6 and 7, regardless of which channels I select in the transmitter. Would like e.g. use channel 6 or 7 for the global gain. What should I do?
Greetings Peter
