@breandanmcewen9 sure, I just whipped up this simple example that you can use as a starting point. I haven't tested it (and probably can't find time to anytime soon), but I'm reasonably confident it will work. It's just meant to pass through (in software) the RC1 control to M3 and the RC2 control to M4. You just plug the RC inputs in to the RC input headers, and you plug the Servo motors into the respective servo headers.
It reads in the pulse width in milliseconds on the RC inputs, then it maps those back into angles for use by the Servo library (which in turn generates corresponding pulse widths on the attached pins). Does that make sense?
