Engine
After each day of flying, fully drain the fuel tank.
Then start the engine and let it idle until the engine
and the fuel line are completely burned off. It is also
suggested that an after-run oil be used to prevent
premature engine corrosion.
Check All Nuts and Bolts
A helicopter is subject to high vibration during
flight. It is important to check that all screws, nuts
and bolts are properly secured after each day
of flying. It is also suggested that you perform a
"quick" inspection between each initial test flight for
approximately the first 6 to 10 flights.
Main Rotor Head
It will be necessary for the main rotor head
dampners to be checked/and or replaced
every 30–50 flights to maintain maximum
rotor head performance.
When replacing the main rotor head dampeners,
apply a light coating of oil to the dampeners to
prolong life.
It is also suggested at this time that the rotor
head thrust bearings be lubricated using a high
speed grease. This will prolong the visibility of
the thrust bearings.
Tail Gear Case
The tail gear case should be repacked with grease
every 50 or so flights. The tail pitch slider and
mechanism should be lightly oiled every 5–10
flights to help reduce wear.
Washout Base
Lubricate the washout base using light oil every
10 –15 flights to ensure smooth operation and
reduce wear. Inspect the washout base every 50–75
flights. If excessive wear is noted, replace as needed.
Tail Pitch Slider
Lubricate the tail pitch slider using light oil
every 5–10 flights to ensure smooth operation
and reduce wear.
Check Ball Link Wear
Check to ensure that all universal links fit freely but
securely to the control balls. If there is excessive
play noted, adjust and/or replace the universal link
in question.
Battery Maintenance
Check to ensure that your batteries are properly
mounted and charged. The most frequent cause
of crashes (aside from pilot error) is battery failure
or disconnection. Be certain that your batteries
are fully charged and limit your flight time to 3 or
4 flights between charging. If more flight time is
required, purchase a reliable quick field charger.
Cleaning
At the end of each flight or flying session, wipe
down your helicopter with a clean towel or rag. This
is also a good time to inspect all parts for tightness
or fatigue. Remember, a clean, well-maintained
helicopter will provide you with many hours of
trouble-free flight.
Ball Links
Check ball links every 15–20 flights for increased
play and looseness. Adjust the ball links using pliers
to tighten the ball race if needed.
