Prerotation and Take-off
x
(If prerotation belts were replaced, it is recommended to powder them with talc)
x
Set brakes on
x
Unlock control stick
x
Check control stick movement range
x
Set control stick in neutral position
x
Set throttle to idle
x
Pull prerotation engaged until Bendix turn on (characteristic sound)
x
After Bendix turns on, hold prerotation lever on in position until rotor accelerate to 100
RPM
x
Firmly continue pulling prerotation lever until rotor RPM stop accelerate(this means
prerotation system has been synchronized)
x
Set prerotation to fully engaged
x
Set throttle lever so the rotor RPM reach 150RPM and then pull the control stick ~10cm
and hold on until rotor reach 180-200RPM
x
Set prerotation to fully disengaged
x
Make sure the prerotation mechanism is deactivated.
x
Release the wheel brake.
x
Pull the control stick backwards and gradually accelerate.
x
At a speed of 40 km/h (22 kt) gently lift the front wheel, observing attitude of gyrocopter.
Prerotation lever is a red lever in central console. Bendix mounted on gyrocopter is
mechanical type.
CAUTION:
After setting prerotation lever to prerotation position, prerotation clutch is engaged
Bendix is turned on and rotor is accelerating. It is forbidden to apply prerotation.
CAUTION:
The gyrocopter tends to lift off the ground prematurely. Attempt to keep the front
wheel about 10 cm above the ground. The front wheel lifted too high can lead to an
unintended take-off at insufficient speed and too large rotor angle, which can lead to an
ascent at a dangerous angle. The machine nose has a low projection(below horizon
line), therefore it is essential to watch the height above the ground.
x
Increasing the throttle, watch for the momentum from the propeller and compensate it by
using the rudder pedals.
x
The lift-off speed is
about 85÷90 km/h (46÷49 kt). After lift
-off, accelerate the gyrocopter
just above the ground to the
speed of 105÷110 km/h (57÷6
0 kt).
