The elevator compensation must actually be acquired through flight, but in our example
the values 25 for half extended and 50 for full are a good start. The elevator goes down
around 16mm with full flaps, and only 8mm with half flaps. This therefore results in a
linear function. In principle, any curve can be simulated with the two compensation
values. This makes sense if for instance half extended flaps generate considerably
more lift than fully extended flaps. The value for the latter would then be changed from
50 to 40 or similar. This is indicated by the curve under these input fields. If one of the
values has a different sign than the other, a red triangle between the two fields alerts
you to this.
In the "Inner flaps" sub item, we now mix the maximum value for spoilers with "120". We
ascertain the correct offset of the inner flaps on the model by beginning with half the
travel either from -1100 or +1100. In the sample model, we came to -600. The servo is
practically at the "stretched" travel end, putting the flap exactly in the profile. If this is not
the case, readjust from -600 in small increments.
We have now done the basic settings and will continue by programming the three
designated flap phases. Flap phase 1 remains empty as the "Basic setting", flap phase
2 sets the flaps to half with the fixed value of 500 for spoilers, and flap phase 3 sets full
flaps with the fixed value of 1000. This "center position" does not necessarily have to be
half the travel. Here, less (often helpful in the early stages) can sometimes be "more".
However, 1100 is the maximum; the servo travel is then fully exhausted and the flaps
are at 90 degrees. For safety reasons, we prefer to leave a bit of a "buffer". We leave
the unused flap phase 4 completely empty.
