Thanks Ed. Now I have to think again :)

Buley, Just so you have the frame of reference firmly in your  mind.  For example, you could  either have the amp meter labeled  with the first order effect  - Lower Pitch /Higher Pitch   or  second order effect  Higher RPM/Lower RPM.  Since it is engine rpm  that I would be primarily interested in, I (if I had a variable  pitch prop) might label the meter with Higher RPM/Lower RPM or  perhaps Increase RPM/Decrease RPM rather than lower pitch/higher  pitch (the latter requires some mental manipulation).  Just a point  of view.

Kelly, I was thinking mounting it vertical. Low pitch down, High   pitch up ? same with the switch.

Bulent,
   Forgot to note that you need to label one side of the ammeter   "pitch increase"
and the other side "pitch decrease"......With a single sweep   ammeter you would
not always know where you were in pitch if you forgot which way   your switch
was wired ("Now was that up or down for more pitch??")......

Bulent,
   When prop is at midpoint of pitch there is essentially no  load  on the motor.
When you add pitch the ammeter needle swings one way (from 0  to ?  amps).
When you reduce pitch you are reversing polarity of the D.C.  motor  and it
turns opposite direction and loads the ammeter to the opposite  side........
