Allgemein gilt für die Servowahl:
So kräftig wie nötig, so schnell wie möglich.
Für die Taumelscheibenservos gilt:
Faustformel: Stellkraft(nicht Haltekraft!) mindestens das 2-3 fache Heligewicht; Geschwindigkeit 0,1s oder aber am besten auch viel viel schneller. Ausserdem sollte das Servo Stellgenau sein, Rückstellgenau, wenig Getriebespiel und geringes Deadband haben. Und natürlich ein Digitalservo sein, das 200Hz Ansteuerfrequenz unterstützt. Die Steuersignale vom System sollten so schnell und präzise wie nur möglich umgesetzt werden.
Note that all the speed is useless if the torque is not enough. In doubt when two servos of a series are only slightly different in speed and torque, normaly the more powerful is in advantage.
