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.
Tail Rotor Belt
Periodically check the tension on the tail drive belt (as shown in Step 1-2, page 8) to insure that it has sufficient tension for proper
engagement. It is especially important to check this after initial test flights.
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 6–10 flights.
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, 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. A clean, well-maintained helicopter will provide you with many hours of trouble-free flight.
