CAUTION
Avoid over-torqueing of the pre-rotator drive! Over-torqueing 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.
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 min. 5400 RPM for take-off. Otherwise, abort take-off
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
When nose comes up allow nose wheel to float at about 10 – 15 cm above the
runway by a balanced reduction of control stick back pressure
Maintain attitude until speed increases and gyroplane lifts off
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.
WARNING
Gyroplanes are fully controllable at very low speeds without exhibiting any
signs of wing stall or soft flight controls, as it would be perceived in a fixed
wing aircraft. However, operation ‘behind the power curve’ may have fatal
consequences during take-off, initial climb or in any other situation within
ground proximity. Always allow aircraft to build-up safe climb speed before
allowing it to gain height.
