I am building a helicopter and would like to use a linear servo like the one on the right in this picture. The exact same servo has been removed from the left side, revealing two strips, one bare copper and the other one black with variable resistive properties. The black one is connected to positive voltage on top, ground on the bottom.
The back side of the slider on the servo is touching these two strips, causing a variable voltage input on the microcontroller on board. I need to get me one of those black strips, and having searched for membrane resistor/potentiometer, I can not find anything that will suit my circuit. It is supposed to be about 20mm long, and the only thing I can find that actually looks like something I need is this one from SparkFun but that is obviosly to large.
All help on the mather is greately appreciated
