17 Final Pre-Flight Check
17.1 Direction of Main and Tail Rotation
Prior to the first flight the tracking
of the rotor blades needs to be ad-
justed. If the tracking is not adjusted
properly, this can cause vibrations
and lead to instability of the helicop-
ter.
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 bla-
de will move below the other.
Make a note of the color of the low-
moving blade. Then turn off the mo-
tor and wait until the rotor head has
come to a halt. Lengthen the linkage
(1) of the rotor blade which was mo-
ving low by unscrewing the ball links
somewhat. Repeat the checking pro-
cedure 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.
