c) Checking the Rotor Blade Retainer
To allow the 4 rotor blades (1) to orientate themselves at a
180° angle to each other during operation, the screws of
the four blade retainers (2) must not be too firmly tightened.
If you pitch the model helicopter to the side by 90°, the rotor
blades must be able to fold slightly downwards as illustrated
in the figure.
d) Installing the Flight Battery
Push the charged flight battery (1) according to the figure,
from the back up to the stop into the battery holder (2) at the
bottom of the model.
The battery cable with the BEC plug (3) and the balancer
connection cable (4) must point back in flight direction.
