The torque figure for a servo is usually given in the specification list. Some manufactures give 2 figures, one with 4.8volts and the other with 6.0 volts. This is the normal voltage range used by the RX. A lot of pilots will use a 6.0volts because it increases the speed and torque of the servos. With an electric powered model the RX voltage is set by the ESC, and the figure will be somewhere between 4.8 and 6.0 volts.
The Torque figure is usually measured 10mm from the center of the output shaft on the top of the servo, unless stated other wise in the specifications. The further away from the center the hole in the servo arm, the less torque is supplied to the control surface. The closer to the center,the greater the torque given to the control surface. The further you move the pushrod away from the center of the servo the more control surface moment you achieve, but with less torque. The closer you move the pushrod to the center the greater the torque but reduced control surface movement.
Moving to the other end of the pushrod at the control surface and control horn. The further the hole in the horn is away from the control surface the greater the leverage will be on the control surface, but with reduced surface movement. The closer the hole in the horn to the control surface the greater the movement but with reduced leverage.
