3.1.3
Assembling and Aligning the Rotor
The blades and hub of the rotor are supplied with numbers to define their orientation in the
assembly kit. By matching numerical-literal marks, insert the rotor blades into the sockets in the
hub. Fit sets of five M8x65 bolts each (with washers at both sides) clipping the hub beams with
every blade. Next, screw down all the ten nuts to the first contact.
Even out the rotor blades by using stretched string, going through the centre of the hub and
along the grooves at the blade tips. The rotor must be placed on two supports with a soft surface
(to avoid damage) so that the strained string goes about 1cm above the central opening in the hub.
If the engine is not aligned properly, it will result in vibrations. The better the alignment of the
rotor is, the greater the comfort of flight is, the smaller the vibrations and the longer the life of the
machine and its subassemblies. When the string does not overlap the hub axle, two people are
needed for help: hold down the blade tips, then push the hub in the right direction. After
alignment, tighten the nuts with a torque spanner, first 18 Nm, next 24 Nm.
The correctness of alignment must be checked in the first flight.
3.1.4
Fitting the Rotor on the Gyrocopter
CAUTION: When placing the rotor, you must stand on the fuselage only in the spots
assigned for this purpose!
•
Make sure the wheel brakes are activated (position 1).
•
Set up and immobilize with tape the control stick in the extreme front position so that the
rotor head disc rests on the brake.
•
Lubricate the master pin with a special lubricant through the central opening in the hub
(?).
•
With the help of another person (and a ladder), raise the rotor and place it on the head.
•
Insert the pin through the head and the hub (making sure the sleeves remain in their
places) and press it down to the end.
•
Tighten the nut, next unscrew it by 1/4 of a rotation and pass the safety cotter pin through
the opening at the end of the pin.
