PILOT OPERATING HANDBOOK
When the pilot moves the stick forwards, the rotor head tilt forwards and the
gyrocopter pitches down.
When the pilot moves the stick backwards, the head tilt backwards and causes
the nose to pitch up.
When the pilot moves stick completely forwards (in practice it is impossible in
flight
- full range only on the ground
), the rotor head disc rests on the fixed
frictional component (bent from
stainless steel) and brakes the rotor.
When the pilot moves the stick to the left, the head tilts to the left and banks the
gyrocopter left.
When the pilot moves the stick to the right, the head tilts to the right and banks
the gyrocopter right.
When the pilot pushes the left pedal, both rudders deflects left. Pushing the
right pedal causes rudders to deflect right. Deflecting the rudder right pushes
the tail left and causes the nose to yaw to the right.
The gyrocopter is equipped with an electrical trim system. This device reduces
the effort required to adjust, or maintain a desired flight attitude. Electrical
trimming is implemented by means of electrical actuators installed in the control
system. By clicking the appropriate trimmer, the corresponding actuator will
move and change the neutral position of control stick.
The trimmer release button changes the position of the actuators towards the
neutral position. This will reduce all forces generated by the trimmers on the
control stick to 0. In order to release the trimmers, the pilot must push the trim
release button and hold it for longer than one second. This changes position of
actuators towards neutral position. This will reduce all forces generated by the
trimmers on control stick. The figure below shows control stick grip.
