CONTROL SURFACE THROW SPECIFICATIONS
The throws are measured at the widest part of the control surface . Adjust the position of the push rods at the control
and/or servo horns to control the amount of throw. You may also use ATV’s if you radio has them but the mechanical
linkages should still be set so that the ATV’s are near 100% for best servo resolution.
