Position the air pressure 
scale exactly as indicated in
the illustration. Make sure 
the servo remains in the 
same exact position as 
before!

Position the air pressure 
scale 

G

 (inches or millibar) 

exactly as indicated in the
     illustration. Use the 
       altimeter's faceplate 
         as an aid, and 
            permanently place
             the faceplate onto 
             the upper casing 
             as well. Mind the 
            proper positioning 
           by using the 
          positioning notches.

Mount the light on 
the inside of the 
upper casing. The 
light needs to 
protrude 0.1” 
(2.5 mm) from 
the edge.

Place lower faceplate E onto the upper casing. Then 
carefully press propeller shaft N into the shaft's opening in 
                                                              the unmodified servo. 
                                                               This needs to be 
                                                               done with great care!

Now place the 
10.000 ft indicator
