D.red (Differentiation reduction)
If you use the aileron differentiation, the aileron effect is strongly
affected by the deflection of the ailerons. Justification: a further
excursion of the one aileron is almost impossble and the control sur-
face moving downward does not reach the "normal" position.
In order to restore this reduced aileron effect, the "differentiation
reduction" reduces the degree of the aileron differentiation.
A 0% value means that the "aileron differentiation" programmed in
the transmitter is held. A value equal to the set percentage of the
aileron differentiation means is completely removed in maximum
butterfly function (with flaps completely out). In case of a reduction
value bigger than the set aileron differentiation will be removed
completely before the full deflection of the flap control stick.
Elevator curve (Brake -> Elevator)
If the flaps extend through the brake control as described previously
in the "Brake settings" menu, the speed of a model is often adversely
affected. The exteded flaps usually produce a tail or nose moment,
the model will react gaining or loosing altitude.
With this mixer, the potential tail or nose moment can be avoided by
a correction value mixed on the elevator. Push the SET button, then
change to the manu page of the 6-point curve mixer "Brake -> ELE".
Programming
The offset you set in the line "Brake offset" of the menu "Model
type" has an effect on this mixer:
When the set offset value is exceeded, the green, vertical bar in the
graphic display, indicating the position of the brake control, moves
away from the edge of the graph. The brake flap control travel auto-
matically respreads to 100%, as described in the "Model type" menu.
The neutral point of the mixer always lies at the left edge of the
graph, independent of the set offset.
Now adjust the Elevator curve in the direction of the opposite end
end points. Set this 6-point curve mixer according to the same prin-
ciple described for the curve mixer in the "Throttle curve" menu.
