Your absolutely correct Mario, in its day it was a high tech ESC, The orange one has an additional wiper on it to give a more positive brake. The green set up was the simlpest form. Its how we ran our throttles in the early race cars. If you wanted reverse you set a micro switch behind the brake so the wiper would switch it. A pain to set up some times since radios did not have end point adjustments (no computer radios).

Bricknick, This idea comes from slotcar racing, instead of holding it in your hand and using the trigger to move the wiper accross the resistor we used a servo. You've probably seen a slot car controller with a heat sink sticking out the top, that would be the orange set up. The orange one has an extra barrel with with an aluminum heat sink through it.

I was actually looking for old servos, I want to do a 360 servo conversion, I haven't found a tutorial on how to do one and I'm sure what I'm doing since I've never done one. I really didn't want to butcher a new servo. So I'll use these and put the throttle barrels back in the box!
