Sailboat servos have a different amount of rotation in degrees. The Futaba 3801 and 3802 have 140 deg. There are also sailboat servos that are drum tiype that will rotate through about 2 1/2 revolutions. Most aircraft servos rarely rotate more than about 60 deg. If you note the specs on each one it will give you the speed on two voltages, 4.8V & 6.0V, that speed is for 60 deg. With the newer computer radios the end point travel is adjustable up to the travel limits built into the servo. If you disassemble one you will find a small protrusion on the final shaft that limits the total travel. No matter what the TX you cannot exceed that limit. To get more throw the servo arm used is the answer. Longer arm, more throw. Adjustment is usually a compromise between the servo arm and the control surface arm. Several types of connections including the clevis at the control surface and adjustable attachments on the servo arm will determne the overall amount of throw.
