I am using this giant servo to rotate an electric prop to steer a video barge.
The servo must rotate 180* to reverse the prop.
In order to extend the angle of rotation, the web says that one should add a resistor to both sides of the servo potentiometer.
I also read that one should parallel the pot with an equal resistance in addition to the 2 series resistors.
This would make the resistance half of what it was and to get the same value as before the servo would have to travel twice the distance.
This seems logical.
Explanations and experience, please.
