The rotorhead
Slide the carbon flybar(67377) through the rotor head. Check that it can rotate freely without binding. Rotate the flybar
26
repeatedly if it shows any sign of binding or sticking. Alternatively, carefully sand the center section of the
flybar evenly with superfine sandpaper. The flybar must rotate smoothly with no binding. Repeat
the above procedure if binding still exists.
Slide the flybar control arms (67368) onto the flybar and retain them with the 2x6 mm
bolts and nuts so that the flybar is centered and the flybar control arms are
parallel to each other. Make sure that the flybar can still be rotated easily, and
that it has just a tiny bit of end float.
Slide the flybar paddles(67371) onto the flybar until they are
flush with the outer sides of the fastening strap. Retain the
paddles with 2x6 mm screws. The paddles must lie parallel
both to each other and also to the flybar control arms. Carefully
align these items because it is very important for correct flight
performance. At the same time as aligning the paddles, you must ensure that the flybar assembly is perfectly balanced.
In order to check the flybar is centered precisely, measure the distance from paddle tip to rotor head center. The distance should
be identical for both paddles. Adjust the position of the flybar if necessary.
To balance the flybar assembly, temporarily disconnect the ball joints from the flybar control arms. The completed flybar
assembly is now free to rock on its two ball bearing pivots. Place the machine on a flat surface and observe the flybar and
Snap the two flybar control links into their sockets in the flybar control arms and onto the longer
ball arms of the upper swashplate ring. Once again, note that the flat side of the link goes to
the inside of the swashplate ball.

paddles. If the same paddle
always drops, measure again to

ensure that they are equidistant
from the rotor head center. If they
are not, correct this. If absolutely
necessary, add a piece of tape to
the lighter paddle to achieve

assembly.The assembly is
correctly balanced when the
flybar paddles sit horizontally
without any tendency to drop to
one side.Check now that all
linkages are correctly attached
and that nothing is too stiff to
move freely.
