NOTE : The throws are measured at the widest part of the elevator, rudder and aileron. Adjust the position of the pushrods
at the control/servo horns to control the amount of throw. You may also use the ATV’s if your transmitter has them but the
mechanical linkages should still be set so that the ATV’s are near 100% for best servo resolution.
