Designed for use in aircraft, car, boat, and helicopter models. Unlike conventional servo arms, they are made of long fiber composites for added strength. Longer versions have increased throw allowing for greater movement in controls.

Includes
4 short, 2 long servo arms that extend in one direction from the servo center
One long arm that extends in two opposing directions from the servo center
One 3-arm horn
