HOW TO: SETTING UP SERVOS

ILLUSTRATIONS BY RICHARD THOMPSON Proper control-surface deflection is the key to good flight control When the servo arm travel is not parallel to the pushrod, you have extra stress on and less control of the pushrod and servo arm. Here, with everything set inline, you have less binding and maximize the servo movement. WITHOUT SMOOTH, non-binding control-surface movements, our planes would be nearly impossible to direct. Linkage systems, including the servo, servo arm, pushrod and...
