Move the centrifugal weight rod (5) up and down ma-
nually and check the linkage mechanics of the blade
holders (6).
The rotor blades (7) must be easily adjustable without
any bearing play in the linkage mechanism or stiffness
or catching in any specific position.
To allow the rotor blades of the main rotor (7) and the
tail rotor (8) to orient themselves at a 180° angle to each
other during operation, the blade retainer screws of the
main rotor (9) and the tail rotor (10) must not be tighte-
ned too firmly.
The rotor blades must still be easily movable in their hol-
ders but must not wobble.
