XK A600 with 3G6G modes?

I could have sworn last night I found an A600 build....

Does anyone have one that they can share, or, can I use the DR template and add 3G6G mode to a switch?

I'd be interested as well. I can't even get the XK A600 to bind despite going through both fine and coarse frequencies. I'd be curious to know how to do that along with switching to 3G/6G modes. I'm assuming it is on Ch5 like the other futaba transmitters?

I had no luck getting mine to bind either
