2.8 Flight controls
The flight controls and the wing flaps of the C42 are actuated by push-rods, torsion
tubes and cables.

The elevator is actuated via the control stick and two push-rods. Actuation direction is
reversed by means of a bellcrank on top of the fuselage tube. Elevator deflection is
limited by two polyamide spacers.

2.8.2 Trim:
The aircraft is available with a mechanical or (as an option) an electrical trim system.
In the case of the mechanical trim system, the trim tab is adjusted by a lever in the
canopy roof frame and a Bowden cable.
The trim tab of the electrical trim system is adjusted via buttons on the control stick
which activate a trim servo and rod. The circuit diagram for the electrical trim system
is to be found in Chapter Error! Reference source not found..
