I am having a problem with Mission Planner where it will not let me set up CH7 and Ch8. My desire is to get ch8 to work as a relay on AUX 5 or 6, but I have no option to do this. This is also preventing me from getting motor inter-lock to work as well. Does anyone know what could be wrong or what I need to do?
Here is a picture of my Extended Tuning section under the Configuration Tab. Note how the option for 7 and 8 are blacked out.
