I think it is much more plug and play than my photos would indicate! I have a tendency to complicate things. A really good manual would be great with the TK20 series. I am mainly concerned with the configuration of the TX as I followed the instructions which should put my throttle controls on my left stick and turn control on my right stick right and left. However, my throttle in on my right along with turn control (which is what I'm use to). But, I have no engine sound which may be due to the incorrect stick position and not being able to identify which stick for turning on the engine sound. I'll figure it out, but it's not as simple as I hoped (and I like simple these days).
I am very excited about learning about it. One small controller is great even if you can't configure custom sounds (I do have a TBS....).
Here's the stick layout:
