15 Final Pre-Flight Check
15.1 Direction of Main and Tail Rotation
Prior to the first flight the tracking of
the rotor blades needs to be adjusted.
If the tracking is not adjusted proper-
ly, this can cause vibrations and lead
to instability of the helicopter.
Apply colored tape to the tip of one
of the rotor blades. Apply tape of a
different color to the tip of the other
rotor blade. When you are ready for
your first flight, increase the rotor
speed to just before lift-off. From a
safe distance, check the rotor disk at
eye-level. Very likely, one rotor blade
will move below the other.
Make a note of the color of the
low-moving blade. Then turn off the
motor and wait until the rotor head
has come to a halt. Lengthen the
linkage (1) of the rotor blade which
was moving low by unscrewing the
ball links somewhat. Repeat the
checking procedure until both rotor
blades move on the same level.
Prior to the first flight double-check
the direction of rotation of the main
rotor head and the tail rotor.
