V-tail, rudder out of sync

Hi
I have a problem with my rudder function. When I turn right the model pitches more up than when I turn left. I am adjusting the pitch in fine tuning - dual rate where minus is down an plus is up.

But how do I adjust so that the pitching is the same for both left and right?

Antwort in Deutch geht auch, Danke.

sound like the mechanical adjustment of the ruders is not excatly the same
and I do not mean how the ruders are attached but how long the way from servo to ruderhorn is, and where the junction is linked in the servo and ruder horn

if the junction from servo horn to ruder horn is exactly the same there should not be any difference in way for both vtail ruders ot at least very little

and exactly therefor is the asymetric DR function and also in v-tail settings you van adjust a lot to compensate mechanical differences plus of cause the general servo settings

Thanks Guido. I will look into the "asymetric DR function". I do not know what it is, but I will do some reading. Also I will look into the values in "Servo Adjust" as I suspect can be of influence if the values are not the same for both servos.

Hi Regnar
In case of V-Tail asymetric Dual Rate is used to control differentiation of deflection.

Thank you Thomas

That is where I adjust so that the model does not pitch, but I can only get it right in i.e. right turns: "100% Auslenkung nach oben und 50% nach unten."

In left turns i need "100% Auslenkung nach oben und 40% nach unten." How can I achieve this?

Using dual rate does not allow you to control differentiation by direction (left / right).

A possible work around: Use two Dual Rate settings one for Rudder left, one for Rudder right. Flip between the two by setting a switch in Rudder neutral position.
