Be careful not to over tighten the
bolts when attaching the tail rotor
blades. The tail blades should be
able to move with a slight amount
of resistance within the tail blade
holders.
To pull the belt through the tail boom, slide a cord through
the boom and fix the belt very carefully at the cord. You can
also use a strand and bend a hook at one of the ends.
Crimping the belt damages the
tensile cords and will result in
premature failure!
Slide the tail case completely onto the boom, align it to
the Compass writing and fix it with the clamp on the rear
side. The two locking bolts ( 8 )must be screwed
completely into the case to pierce the boom. After this
step, the angle of the writing can not be adjusted any
more!
