Enter the planes maximum airspeed in km/h
Enter the Average Chord dimension of the control surface.
Enter the Length of the control surface.
Select the Maximum Servo Deflection in degrees from neutral/center.
Select the Maximum Deflection of the Control Surface in degrees from neutral/center.
If the Servo has a full travel of 60 degrees, from center 30 degrees would be entered. If the
control surface has a full sweep angle of 40 degrees. From Center or the neutral point, 20 degrees would be entered.
The calculator only calculates one control surface per servo. If you are using one servo for two control surfaces, the calculated torque must be doubled.
This in many cases is common for the aileron channel.
