Do you perhaps mean "motor stick" rather than "motor shaft"? The propeller shaft is the wire hook that attaches to the front of the rubber motor.

Is this a biplane to be flown in the Wright Stuff event for the Science Olympiad competition?

If it is, or if it is intended as a duration model, then I would put the lower wing above the motor stick at a distance of 0.5 to 1.0 wing chords above the motor stick and the upper wing 1.0 wing chords above the lower wing.

Others probably can give you a better answer.

  Ok, just to clarify on things:
  The "motor shaft" is the component of the plane which contains the
  propeller. Also the wings and the fin are attached to this shaft.

  So my question is this, what should the vertical distance between the
  motor shaft and the lower be?
