CAUTION
Avoid overtorqing of the pre-rotator drive! Overtorqing will occur if RPM/power
is fed excessively or abruptly. In case of a stalling engine, release pre-rotator
button temporarily. Do not yank the throttle control while the clutch is engaged!
NOTE
Perform take-off into the wind and with least possible crosswind component.
NOTE
To avoid unintended engagement in flight the pre-rotator can only be activated
with the control stick in its most forward position, and (if fitted) the canopy
locked closed.
WARNING
In the event of pre-rotator failure, STOP and rectify the fault. Do NOT attempt to
pre-spin by hand, as this involves considerable personal risk if the engine is
running.
4.9 Take-off Run
Check engine has reached full power for take-off. Otherwise, abort take-off
Commencing the take-off run with high rotor rpm (280-320) and the stick fully back
means that there is a high starting drag load. The aircraft has to accelerate to approx.
50mph (depending on loading) to take off, and achieve the rotor rpm for the loading
conditions.
Therefore, to minimise the drag and enable maximum acceleration at high rotor rpm,
move the stick forwards to approximately the mid position as the aircraft starts to
move. Monitor rotor rpm carefully ensuring that it is increasing, if the stick is too far
forwards the rotor rpm will decay, and a serious accident can be caused!
When nose comes up allow nose wheel to float at about 10 – 15 cm above the
runway by a balanced change of control stick position
Minimize lateral drift by applying appropriate lateral control stick input into cross wind
direction
Maintain directional control i.e. runway alignment with sensitive pedal input
Maintain attitude until speed increases and gyroplane lifts off (at about 50mph,
depending on loading and rotor)
Allow gyroplane to build-up speed in ground effect
CSP/VPP: With a variable pitch propeller installed, refer to the
respective flight manual supplement in CHAPTER 9 for correct power
setting and handling procedure.
