It is important to check that all screws, nuts and bolts
are properly secured after each day of ying. It is
alsosuggestedthatyouperforma“quick”inspection
between each initial test ight for approximately the
rst 6 to 10 ights.
Main Rotor Head
Periodically check the main rotor head dampeners to
maintain maximum rotor head performance.
When reassembling the main rotor head, 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.
Washout Base
Lubricate the washout base using light oil every 10
–15 ights to ensure smooth operation and reduce
wear. Inspect the washout base every 50–75 ights. If
excessive wear is noted, replace as needed.
Tail Pitch Slider
Lubricate the tail pitch slider using light oil every 5–10
ights to ensure smooth operation and reduce wear.
Check Ball Link Wear

securely to the control balls. If there is excessive play

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 ight time to 3 or 4 ights
betweencharging.Ifmoreighttimeisrequired,
