7. RUDDER:
On earlier models, the rudder stops are not adjustable. The rudder travel should not
change if this part of the airplane is not damaged. If these need to be adjusted, it can be
done by welding on to the end of the stops to decrease the travel and filing the stops off
to increase the travel. On later models these stops are adjustable by screwing them in
and out.
Check the rudder travel for 21° ±1° right and left.
8. ELEVATORS:
Elevator control movements are up 25° ±2°, down 21° ±1°. Stops are located on the
vertical tail rear spar just inside the inspection plate. Proper cable tension is 25 to 40 lbs.
9. ELEVATOR TRIM TAB:
Elevator trim tab movement is 14° ± 1° up, 25° ± 1° down for s/n 3-43 and for s/n 44–
94 is 8° + 2°/-1° up, 25° ± 1° down. (With wheel type trim control, if installed, movement
is 11° ± 3° up, 25° ± 1° down.) If adjustment is needed, it may be done at the turnbuckles
located just aft of the trim control. Proper cable tension is 15 to 25 lbs.
10. RUDDER TAB:
This tab is interconnected with the aileron system to automatically coordinate aileron
and rudder controls for simplified handling in the air. (It may be used as a rudder trim tab
to make the airplane trim in cruise.) This tab may be ground adjusted by changing the
position of the tab cables where they attach to the aileron cables located just over the
front doors on the inside of the airplane. Normally, the tab should be streamlined with the
rudder when the aileron and rudder controls are centered.
The tab travel is 48° ±4° right or left. Proper cable tension is 5 to 10 lbs.
CAUTION: Make sure tab is free at extreme aileron travel.
NOTE: The "Rudder Trim Control" on the instrument panel pulls on a spring attached to
the right rudder pedal. It is not connected to the tab on the rudder.
