parallax servo and propeller part 2

shmow

how do i keep track of the servo's position (return to original position) if there's lag or slippage after several rotations?

If you are concerned that the requested position has slipped from the desired position, you need some position sensor. Try looking up rotary encoders, or Beau's very cool way to ask the servo itself for its position
