Turn the core mechanic and tail boom upside down then pull the belt toward the front out of the tail boom and align it in
such a manner, that it runs straight without being twisted.
The imprinted arrows signify the moving directions of the belt strands. The
red arrow
signifies the working strand of the
belt and the
green arrow
signifies the relaxed strand. If you pull the belt into the direction of the
red arrow
, the tail blades
must rotate in the correct direction (clockwise at the front view on top of the tail rotor).
Look from the front to the tail boom. Twist the belt 90° to the left (counterclockwise) (
see circular red arrow
) until the loop
is in a horizontal position and no more vertical as shown in the picture.
Guide the belt through the two clamping flanges without twisting further until you can lay the belt over the belt disc. At the
same time slide also the tail boom into the two clamping flanges. In the picture the
red arrow
signifies the working strand
of the belt and the
green arrow
signifies the relaxed strand.
If you look from the top to the pinion shaft the pinion shaft unit will turn clockwise in operation.
If you turn the motor in the right direction, with the free wheel connecting the tail has to turn in the right direction as
described above.
Attention!
The tail boom will not be clamped for the moment.
