b) Checking the Rotor Blade Retainer
To allow the four main rotor blades (1) to automatically
orient themselves at a 180° angle to each other during
ight,thebladeretainerscrews(2)reachingintotheblade
retainersfromabovemustnotbetightenedtoormly.If
you pitch the model helicopter to the side by 90°, the rotor
blades must be able to fold downwards on their own as
illustratedinthetopgure.
Attention!
Do not loosen the fastening screws too much;
if you do, the tracking of the rotor blades will no
longer correspond, and the blade tips will run at
different heights.
Caution!
Only use a suitable screwdriver for tightening
screws and ensure that you do not use exces-
sive force. The threads or the screw material
may be damaged otherwise.
c) Checking the Centrifugal Weight
The centrifugal weight (1) must be easily movable, just like
the main rotor blades.
Manually move the centrifugal weight up and down on one
side(seearrowsingure7)andensurethattheballjoints
(2) can be moved easily.
The mechanics must run smoothly, but should not have
any play in their bearings.
