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 dampners, apply a light coating of oil to the
dampners 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 oiled lightly every 5–10 flights to help
reduce wear.
Washout Base
Lubricate the washout base using light oil every 10 –15 flights to insure
smooth operating and reduce wear. Inspect the washout base every 50 –75 flights.
If excess wear is noted, replace as needed.
Tail Pitch Slider
Lubricate the tail pitch slider using light oil every 5–10 flights to insure
smooth operation and reduce wear.
Check Ball Link Wear
Check to insure 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 insure 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 plyers to tighten the ball race if needed.
