RUDDER
The metal-covered rudder is attached to the vertical stabilizer at three hinge points. The
rudder control cable is connected directly from the rudder horn to the rudder pedal
adjustment channels. The left and right rudder cables route from the adjustment
channels aft around pulleys where they pass through the fuselage side skins and attach
to adjustment straps on the rudder horn. A spring-loaded balance cable is routed
between the pedal adjusting channels and forward around pivoted pulleys located on the
hopper rear wall. The rudder controls are interconnected by springs to the aileron system
so that a wing may be lifted with rudder alone. This feature provides a convenience
during cross-country flight and is an added safety feature in case the aileron system
becomes inoperative. (Fig. 7-3)
