I just thought of an idea for making a servo for steering... I'm not 100% sure
this will work, as I don't have an angle sensor, but here you go:
You'll need a fixed width font:

Note that just behind the Micromotor there is a space of 4 plates which equal 2
stud width... Two of those plates are the motor lead brick, and the other 2 are
spacers so that the plates on top & bottom that will hold everything together
will fit.
Like I said. I don't know If this will work, but if nobody understands what I
mean here, I'll try to LDraw it, if somebody emails me.
