Do not place any small loose articles in the baggage
compartment. All baggage must be stowed in containers such
as packs, suitcases or bags. A small article, if misplaced, could
bind up a control linkage causing loss of control of the aircraft.
6-8 CONTROL SYSTEM
The primary controls are of a conventional 3-axis design using dual
stick controls for pitch and roll and dual rudder pedals for yaw.
Positive travel stops are provided for all primary controls.
The large Fowler flaps are manually actuated by a lever mounted
between the seats. A thumb-operated button releases a spring-loaded
locking pin from a detent in a ratchet plate, allowing the lever to be
moved to the desired position. The ratchet plate has three positions for
flap extensions from 0° to 35°.
The elevator, aileron and flap control interconnections are by cables to
bellcranks, with a pushrod connecting each bellcrank to its control
surface. The rudder is controlled by cables directly to the rudder
actuator yoke. The aileron and flap control cables are routed in such a
way that they need not be disconnected when the wings are folded.
The Sportsman elevator trim system uses a large trim tab in the
elevator. Standard elevator trim is manually operated by a cockpit-
mounted trim wheel; electric trim is optional.
