Thanks a lot for the code, it will be interesting on my larger scale RC's i'm sure
For the moment, i've found a difference in measurement of the resistance of the controller/motor couple when running forward, backward, braking and still. So i'm digging in this direction for the moment with a resistor bridge to "see" the resistance in the arduino and interpret it.
About the turbo overrun, interesting idea, but we need to know the conditions where this can be observed to reproduce it, i don't like to randomize. Maybe trigger the "flame" at the beginning of acceleration (from still to movement), at the release of the accelerator, and if braking some random trigger (we are not braking so much time
) until stop. This can be as tricky as the brake light
Your blog is in my favorites, interesting ideas
