Move the two control sticks for the pitch/tail function (ill.
1a, pos. 7) and the nick/roll function (ill. 1a, pos 8) into
middle position. The trim controls for the control functions
(ill. 1a, pos. 9, 10, 11, 12) should be moved to middle
position as well. The servo arms of the three swashplate
servos (1) should now be at a 90°-angle to the casing.
Check if the swashplate (2) is parallel to the upper edge
of the mechanical unit (see auxiliary lines).
If an adjustment has to be made, change the length of the
linkage (3). Take off the linkage, turn the ball head as
needed (4) and clip the linkage (3) back on.
Practical tip:
Illustration 8
A pair of ball link pliers is a useful tool to take off and clip
on the linkage. We offer suitable ball link pliers as an
accessory.
Next, the two paddles (1) of the auxiliary rotor are checked.
The paddles must have the same distance (A, see ill. 9b)
to the centrepiece (3). They must also be absolutely par-
allel to each other and to the blade holders (2) (see
auxiliary line in ill. 9a)
To check the correct position of the paddles to the blade
holders, look at the rotor head from the side. Since each
paddle has an adjusting ring with a grub screw (4), you
can easily adjust the paddles by undoing the screw, moving
them and then tightening the screw again.
During flight, the two rotor blades must be able to align
themselves due to the centrifugal force. The rotor retaining
Illustration 9a
screws (5) should therefore only be tightened to the point
where the rotor blades can still swing downwards when
you tilt your model 90° to one side.
