Radiolink AT9 Controller

I’m having some trouble getting to know my Radiolink AT9 Controller, specifically the switches. the 3 Position SwC gives me three flight modes, but none of the other switches register anything in APM planner when selected. The controller has 8 switches – it would be great if I could assign a flight mode to each one, but it isn’t clear how to do this.

Well, I figured it out. Turns out, you have to learn Chinese first.
