How to make better RC controls

I've seen a lot of vehicles with subpar controls. I'm able to forgive it, since circuits are complicated and scary. This level, an RC module with a reverse-compatible slider that also accepts A/D, attempts to explain some of them. Just follow the wires in and out of the graphers and dbuggers that let you see their values to see what the components do.

The one on the right is exactly like the one on the left, just without the debugging.
