Servo Savers are basically servo horns or arms that are designed to take the brunt of a large jolt so that your servo geartrain does not! They have a U-shaped spring inside that takes the shock instead. We highly recommend them for any servo that repeatedly takes a beating! This one is for Futaba servos, white. 1 Each Servo Saver (futaba) SASSS2$5.99 Copyright © 2003-2008 E-Clec-Tech. All rights reserved.
