Hi and thanks. First, my fat thumbs typo corrections. RC servo or a RC speed control for locomotion. I have been working on an AeroQuad for a while and was able to make everything function as expected. But that was easy as I didn't learn anything on writing code with it. I have nothing, as far as code is concerned written. I am an admitted rc addict and can make anything radio controlled. This project is due as soon as I can finish it. My son donated a small rc car for the test platform XD .
