Daily Check

After one day of helicopter flying, be certain to do the following checks!
WARNING: Make sure that all screws are securely tightened and all parts are in best condition! Damaged
Wipe off any dirt or oil deposits from your helicopter.

Wearing Parts

WARNING: When replacing defect parts with new ones, please only use Kyosho brand genuine parts.
Ball End / Linkage Ball
Replace ball ends if they come easily
off. Replace balls with the first signs of
scratches.
Ball Bearing
open-type
Replace ball bearings if their action has
worsened. Oil open-type bearings. Do
not oil sealed bearings.
Other Parts
Since engines, Ni-Cd batteries, servos and gyros also wear down, they require a regular
maintenance and eventually replacement.

Overhaul

After about 50 tanks of flight, a thorough-going overhaul is necessary. Worn components must be replaced. Components being exposed
to mechanical stress (main rotor, rotor head, tail rotor center hub) and the drive train must be overhauled in particular and be greased.
When reassembling, use screw locking compound on all screws to prevent loosening.
If your helicopter crashes
A thorough-going check is also required if your helicopter crashed, the main rotor blades hit the tail boom and other components were
exposed to any strong impact.
32
parts should be immediately replaced by new ones and loose screws retightened. Failing to do
so will inevitably result in accidents such as crashs!
Swashplate
Replace the swashplate with defect ball
bearings. Should the swashplateÕs
action not be smooth, clean it and oil
the inner balls.
Clutch
sealed-type
Replace the clutch if it does not disen--
gage or if it engages at low throttle.

MAINTENANCE

Replace gears with stripped teeth. On
this occasion, ensure correct gear
meshing.
Replace with first signs of cracks, defor--
mation or quality deterioration.
