5. AILERONS:
Adjust the ailerons to streamline position by placing a straight edge on the bottom of the
wing chordwise at the inboard end of the aileron. Then adjust the turnbuckles in the aileron
system so the control wheels are centered and there is a gap of zero to ¼ inch between the
straight edge and the trailing edge of the aileron.
Check the aileron travel for 20
° ±
1
°
up and 20
° ±
1
°
down. Adjust turnbuckles to stay within
these limits. Proper cable tension is 15 to 25 lbs.
6. FLAPS:
Adjust the first notch (0
°
) flap position to be aligned with the aileron trailing edge with the
ailerons centered. Check the flap travel with flap handle at fully retracted (handle down) posi-
tion for negative 7
° ±
1
°
up, and 24
° ±
3
°
down for second notch, 40
° ±
3
°
down for third notch.
Adjustment, if needed, may be accomplished by adjusting turnbuckles located above front
seats through headliner. Proper cable tension is 60 lbs.
±
10 lbs.
7. RUDDER:
Set-up for Installation of Rudder Cables:
Lock rudder to vertical stabilizer using a C-Clamp and two (2) padded wood blocks. Es-
tablish the rudder “Neutral Position” by measuring (and holding) a distance of 6” between the
backside of the rudder pedal(s) to the face of the interior firewall. Note: Make sure the interior
(firewall) insulation and (firewall) vinyl covering/upholstery is adequately compressed during
this initial set-up phase. A wooden spacer of the appropriate length (a 2x4 wooden block
works fine) is ideal to hold the given distance during the rudder-rigging process. Install rudder
cables and related-hardware.
Check the rudder travel for 21 ° ± 1 ° right and left. Rudder cable tension is controlled by
springs, and the cables should not be slack with the rudder centered. Rudder trim may be ac-
complished by adjusting the tension of the rudder centering springs located behind the rear
bulkhead. Keep springs as short as possible but never less than 4 ½ inches from end coil to
end coil with the rudder centered.
8. ELEVATORS:
Elevator control movements are up 30 ° ± 1 ° , down 20 ° ± 1 ° . Stops are located on the verti-
cal tail rear spar just inside the inspection plate. Proper cable tension is 25 to 45 lbs.
CAUTION - BEFORE FLIGHT whenever elevator cables are reconnected or new cables in-
stalled: Always check operation of elevators after a cable reconnect by pulling back on the
control wheel and ascertain that the elevators are in the UP position.
