* Do not fully tighten at this time. These bolts
will be secured in Step 5-10.
**Note: For increased tail boom mounting
strength, it is suggested that the
2 halves of the tail boom carrier be
sanded on a flat surface using
80-100 grit sandpaper. By removing
material from the inside flange,
a more positive tail boom connection
can be achieved.

Slide the tail boom through the
tail boom carrier and engage the
tail drive belt over the front pulley.
Be certain to note the correct
rotation (direction shown below).
Set the belt tension per the
directions below.
Secure bolts completly
after inserting the tail
boom, making sure that
the tail output shaft is
exactly 90° to the
main rotor shaft.
Tail Output
Shaft Pulley
Rotate the tail drive belt in the direction
shown before installing it onto the front
pulley. It is extremely important to install
the belt in the proper direction to insure
correct rotation of the tail rotor blades.
Belt tension should be set so
when pressing with your finger,
the sides of the belt do not come
in contact with each other. If
unsure, it is always better to set
the belt tension too tight than
too loose.
