This servo saver is designed to protect the gears inside of a servo by twisting or breaking in the event of a large shock. These are commonly used on RC vehicles and robots that experience rough environments.
Each arm features 3mm diameter holes and should be compatible with most linkages. I have also created a version with 1.5mm holes if needed.
I DO NOT guarantee or warranty the effectiveness of this device in protecting your servos. Use with caution.
