Maximum and minimum pitch:
Now adjust the maximum and minimum pitch values using the setup of the 3 axis stabilisation system (chapter XII – p.44).
At first adjust the maximum value by adding the 6 mm lock 0394b to the 12mm lock 0394a and adjusting the way
electronically such that the swash plate rests on the 18mm strong support at maximum pitch. The minimum is determined
symmetrically to the other side. It can be checked by putting only the 6mm lock under the swash plate.
The adjusted collective way of +/- 6mm according to the dead centre position corresponds to a blade altering angle of approx.
+/- 13 degrees. This is a good allround value which does not overload the motor and offers well-balanced flight properties.
Extreme pilots can increase the value later to a certain extent, however I consider 15 degrees to be the absolute limit. While
hovering you will have great difficulties in keeping the helicopter at a height. It can also result in mechanical problems
regarding the rods at a pitch of more than 13 degrees at full cyclic deflections. In every case always make a test and add full
cyclic deflection at maximum pitch positions. Then look if the rods or the swash plate collide at a certain position. It is normal
that full cyclic deflections in the pitch end positions lead to an uneven movement of the swash plate because due to the large
angle differences the servo arms move in extremely different ways. However, this is not problematic because at these pitch
values you usually do not add any full cyclic deflections.
Finally clip the rotordisk 0103 into the 5mm hole of the centre hub now .
