NOVUS FP – REPLACING THE TAIL SHAFT AND TAIL ROTOR
Use a flat blade screw driver to carefully pry the tail rotor from the tail rotor shaft.
Slide the tail drive gear off of
the shaft. Slide the tail rotor
shaft out the opposite side of
the tail rotor case. Slide the
new tail rotor shaft into the
tail rotor housing. Slide the
tail drive gear onto the shaft
(the step faces inward) and
press the tail rotor onto the
shaft, ensuring that the two
protrusions on the tail rotor
line up properly with the tail
drive gear.
NOVUS FP – REPLACE THE TAILBOOM
Loosen the tail boom screw
and unplug the tail motor wire
from the E-Board. It will be
necessary to cut the motor
wires near the tail motor where
the heat shrink tubing has been
applied. While holding onto
the tail motor connector at the
front, slowly slide the tail boom
out of the frame and off the tail
motor wires. If you notice any
damage to the tail motor wires
it will be necessary to replace
the tail motor wire harness.
Slide the tail motor wires into the tail boom and reinstall the tail boom onto the
helicopter. On the old tail boom, remove the lower tail motor retention screw and
remove the tail motor gear box assembly. Run the tail motor wires through the tail
motor gear box assembly. Ensure that the tail boom is pressed far enough into the
main frame and tighten the tail boom screw on the main frame. Ensure that the
tail gear box assembly is pressed far enough onto the tail boom and ensure that
the tail rotor is vertically aligned with the main shaft. Tighten the lower tail gear
box retention screw once you are certain that everything is correct. Re-solder the
tail motor wires to the tail rotor wire harness and install heat shrink tubing. Ensure
everything is correctly installed and all bolts have been tightened.
