XBus programmableservo S8911BL 2K BIG BLOCK type with increased gear thickness is now available.Top case and gears have been redesigned to increase servo durability. New Topcase has been integrated with iron bushing to prevent shaft movement while thehigh torque stress distortion is occurring. This new iron bushing inside thetop case will avoid gear wear or damage as well. The metal iron gear alsohas been improved by increasing the thickness of the gears. Distortion caused byrepetitive movements is greatly reduced. It also contributes to the further extensionof the longevity of brushless servos.
