17. Optimizing the flying characteristics
If - after a few flights - you develop a feeling for your helicopter, you can carry out first optimizations.
Setting the alignment
To achieve accurate control and flying characteristics, the two rotor blades must to be running at the same level within
the rotor rotation plane. One rotor blade should be marked with a strip of coloured adhesive tape to allow you to check
and also adjust this alignment. Increase the rotor speed with the helicopter on the ground to the point where the
helicopter is about to take off. If you now look at the rotor rotation plane from the side, you will immediately see if the
blades are running at different heights (A) or accurately on the same height (B).
Caution!
When the rotor head has stopped, disconnect the flight battery from the speed controller before making
any adjustments to the rotor head to prevent the mechanical unit from starting unintentionally.
The rotor blades are controlled from the back via a mixing
lever (1) with a linkage (2) which can be adjusted in length.
If the respective rotor blade (3) is too high, the linkage of
this rotor blade must be lengthened. This reduces the
angle of attack of the rotor blade and thus causes it to be
lower due to the weaker lift.
To do this, carefully unhitch the lower ball-headed eyelet
(4) of the linkage and turn the eyelet by one revolution
anti-clockwise away from the linkage. Reattach the eyelet
and make sure the linkage fits correctly.
Operate the helicopter again and check whether your
adjustment has been sufficient. You can alternatively
shorten the linkage of the blade which is running too low.
This results in a greater lift of the blade which will
consequently run higher.
