CONTROL SYSTEM

GENERAL
All control surfaces are cable operated from the front or rear seat. An X4130 steel torque tube connects the
front and rear control sticks for coordinated longitudinal control.

The two sticks are mounted on a second X4130 tube supported by fibre bearing blocks on front and rear
ends for coordinated lateral control. A bell crank attached to the rear of this tube actuates the mechanism
producing aileron control. Pulleys, sectors and aileron hinge attachments are ball bearing providing a
minimum of friction in the system.

AILERON
The rigging load on the aileron system is 45 to 55 pounds and can be adjusted at the sides of the cabin
enclosure or top by opening the slide fastener and adjusting the turnbuckles.

RUDDER
Rudder tension is spring loaded through springs attached to the rudder pedal and floor frame. No
adjustment is necessary.

ELEVATOR

Adjustment may be accomplished at the turnbuckles located just aft of the rear stick. Rigging load should
be 45 to 55 pounds.

ELEVATOR TAB
A slide fastener opening in the top of the cabin provides access to the tab friction control knob. By tightening
or loosening the knurled knob, the desired amount of friction may be applied to the tab control adjustment
arm. Rigging load of 15 to 20 pounds may be adjusted at the turnbuckles located immediately fore of the
tab assembly on the left elevator.
