Jace,
Thanks for the link. After seeing your vids, I wonder there is a video on youtube somewhere that details a mechanism where a servo was placed on top of the steering cover--was that by any chance your work? That was definitely original!
A quick update on my progress, many parts are ordered, and currently I have gotten the geared motors. I probably will follow Avant's link info where a person have installed the small motor in a 130 can. But my only concern is the motor is only spec at 3v, and whether the over voltage will kill the motor...
Anyway, I shall keep updating this thread as we go along.
